Introducción

En Obras Civiles, muchos proyectos de movimientos de tierra exigen que la plataforma este acabada con cuidado, de tal forma que la superficie sea uniforme y plana, sin ondulaciones o surcos. Aunque un conductor habilidoso puede conseguir, en muchos casos con un buldozer, resultados mas adecuados, la Motoniveladora ha sido concebida especialmente para refinar la explanada, la superficie de la subbase en las carreteras, así como los desmontes y los rellenos, para igualar taludes de las presas de tierra y conservar los caminos de arrastre de obras. Se trata de una maquina de auto-desplazable que sustenta sobre sus dos o tres ejes. Los grandes proyectos de carreteras de los últimos años han necesitado maquinas mas pesadas y robustas, y la configuración con tres ejes ha demostrado ser la necesaria para poder soportar el potente motor que llevan y proporcionar mejor tracción, por lo que actualmente es el tipo de mayor aceptación.

Objetivos

Objetivo principal

El objetivo del trabajo es dar a conocer al curso la importancia de la Motoniveladora en obras de movimiento de tierras para la cual fue concebida.

Objetivos Específicos

Conocer e identificar sus componentes.

Comprender su método de trabajo en obra.

La Motoniveladora

En el mercado podemos encontrar diferentes Modelos de Motoniveladoras, las cuales se clasifican según su peso y potencia de acuerdo a las funciones especificas para las cuales son requeridas. Para nuestro trabajo trabajaremos con un modelo estándar de la fábrica volvo modelo G720B. La G720B es una de las máquinas más populares de la línea de Motoniveladoras Volvo. Con 15 422 kg (34 000 lb) y 164 -198 CV (122-148 kW), estas unidades ofrecen una elevada productividad en todas las aplicaciones.

Definición:

Máquina muy versátil usada para mover tierra u otro material suelto.

Su función principal es nivelar, modelar o dar la pendiente necesaria al material en que trabaja. Se considera como una máquina de terminación superficial.

Su versatilidad esta dada por los diferentes movimientos de la hoja, como por la serie de accesorios que puede tener.

Puede imitar todo los tipos de tractores, pero su diferencia radica en que la Motoniveladora es más frágil, ya que no es capaz de aplicar la potencia de movimiento ni la de corte del tractor.

Debido a esto es más utilizada en tareas de acabado o trabajos de precisión.

Los trabajos más habituales de una Motoniveladora son los siguientes:

Extendido de una hilera de material descargado por los camiones y posterior nivelación.

Refino de explanadas

Reperfilado de taludes.

Excavación, reperfilado y conservación de las cunetas en la tierra.Mantenimiento y conservación

Importante: Las Motoniveladoras no son máquinas para la producción, sino para realizar acabados, ya sea nivelación y/o refino.

Componentes de la Motoniveladora

1. Pie de la hoja vertedera

Es el extremo más adelantado de la hoja en relación con el sentido de marcha. Es, generalmente, el extremo que está más próximo a las ruedas delanteras de la máquina.

2. Talón de la hoja vertederaEs el extremo más retrasado de la hoja en relación con el sentido de marcha. Es, generalmente, el extremo que está más próximo a las ruedas en tándem de la máquina.

3. Giro del círculo

Permite una rotación de 360 grados del círculo y la hoja vertedera para adaptar el ángulo de la hoja al tipo de material o características de la aplicación. El ángulo de la hoja es muy importante porque permite que el material ruede a lo largo de ella, aumentando la productividad de la Motoniveladora.

Normalmente, una Motoniveladora desplaza el material de un lado al otro del área que se está nivelando, en vez de empujarlo hacia adelante. Este desplazamiento del material por rodadura de un lado a otro de la hoja, hasta su vertido lateral, requiere menos potencia motor que si tuviera que ser empujado. Para conseguir esta acción de rodadura hay que hacer uso simultáneamente de varias de las posibilidades de la máquina, como el giro del círculo, el desplazamiento lateral de la barra de tiro y la inclinación de la hoja vertedera. (Se dispone, como opción, de un embrague deslizante ajustable para proteger el mando del círculo de las altas fuerzas horizontales que se producen en las aplicaciones severas.

Dientes endurecidos, cortados en el exterior del círculo para máximo esfuerzo de 0palanca y mínimo desgaste. El círculo se apoya en seis puntos mediante tres placas de fijación ajustables y tres zapatas-guía ajustables, para máximo apoyo

del círculo y mejor distribución de la carga. Las placas y zapatas revestidas de DURAMIDEMR evitan el contacto entre metales y aseguran

máxima vida útil. DURAMIDEMR es un material de apoyo sintético que maximiza la vida de servicio y disminuye el mantenimiento del círculo.

Acero 1050

Gracias a la buena penetración de temple que tiene este acero, es apto para piezas de maquinas que deban soportar esfuerzos altos, longitudinales y transversales, pero sin impactos continuos.

Acero al boro

El Boro logra aumentar la capacidad de endurecimiento cuando el acero esta totalmente desoxidado. Una pequeña cantidad de Boro, (0.001%) tiene un efecto marcado en el endurecimiento del acero, ya que también se combina con el carbono para formar los carburos que dan al acero características de revestimiento duro.

Temple y revenido:

Al dar a los aceros al carbono un temple y revenido se consiguen muy buenas características cuando el perfil es delgado. En un acero al carbono bien templado o revenido, el valor del límite elástico suele llegar a ser un 75% de la carga de rotura.

5. Bastidor:

El bastidor o chasis es el elemento metalico que sirve de soporte a todos los mecanismos que llevan consigo una Motoniveladora.

6. Eje delantero

Las ruedas delanteras soportan una larga viga puente de donde cuelga la hoja vertedera. En algunos tipos de maquinas la viga va unida mediante un pivote al chasis trasero para permitir el giro en un circulo reducido, una mayor manejabilidad, y permite avanzar con el bastidor en ángulo en relación con sentido de marcha, manteniendo las ruedas paralelas. En otros tipos la unión es rígida y el control de dirección solo es posible en el eje delantero. El diseño permite que las ruedas: (a) se inclinen unos 18º a cada lado de la vertical para resistir los empujes laterales cuando, por ejemplo, la hoja vertedera trabaja en posición inclinada, y (b) trabajen a diferentes niveles para perfilar cunetas, peraltes, y otras tareas análogas . La combinación de ambos dispositivos permite que la dirección pueda controlarse sin necesidad de concentración excesiva por parte del conductor, liberando así su atención a favor de la hoja vertedera.

Mantenimiento de la Motoniveladora

Se puede definir mantenimiento como el conjunto de actividades que se realizan a un sistema, equipo o componente para asegurar que continúe desempeñando las funciones deseadas dentro de un contexto operacional determinado.

TIPOS DE MANTENIMIENTO

Según el tipo de actividad el mantenimiento se clasificar de la siguiente manera:

MANTENIMIENTO CORRECTIVO

El mantenimiento correctivo es una estrategia en la cual se permite funcionar el equipo hasta la falla y solo hasta ese momento se decide realizar la reparación o cambio de pieza.

MANTENIMIENTO PREVENTIVO

El mantenimiento preventivo es una estrategia en la cual se programan periódicamente las intervenciones en los equipos, con el objeto principal de inspeccionar, reparar, conservar y/o reemplazar componentes. Las intervenciones se realizan aún cuando la máquina este operando satisfactoriamente.

MANTENIMIENTO PREDICTIVO

El mantenimiento predictivo, es una estrategia que busca por medio de la medición y el análisis de diversos síntomas que la máquina emite al exterior, establecer su condición mecánica y su evolución en el tiempo. Una de sus grandes ventajas es que se lleva a cabo mientras la máquina está funcionando y solo se programa su detención cuando se detecta un problema y se desea corregir.

MANTENIMIENTO PROACTIVO

El mantenimiento proactivo es una estrategia de mantenimiento que pretende maximizar la vida útil operativa de las máquinas y sus componentes, identificando y corrigiendo las causas que originan la falla.

BENEFICIOS DEL MANTENIMIENTO

Los beneficios más relevantes alcanzados en una organización con la aplicación de un mantenimiento oportuno son: la disminución del riesgo, previniendo la probabilidad de ocurrencia de fallas indeseables, la mejora de los niveles de eficiencia de la instalación o equipo, la reducción de costos operativos e incremento de la producción.

Además de estos prolonga la vida útil de los equipos, cumplimiento de los requerimientos de seguridad y el mejoramiento de la imagen de la organización con un realce de la impresión de clientes y entorno, así como el incremento de la moral de los trabajadores que operan los equipos e instalaciones.

OBJETIVOS DEL MANTENIMIENTO

En el caso del mantenimiento su organización e información debe estar encaminada a la permanente consecución de los siguientes objetivos:

Optimización de la disponibilidad del equipo productivo.

Disminución de los costos de mantenimiento.

Optimización de los recursos humanos.

Maximización de la vida de los equipos.

Métodos de trabajo de la Motoniveladora

La hoja vertedera puede trabajar en diversas posiciones para:

Nivelar y reperfilar, en plano horizontal, con la hoja centrada o girada hacia un lado u otro (fig. 6.5.a.). Si la hoja se coloca en horizontal pero con un cierto ángulo respecto a la marcha el material se amasará hacia el extremo de la hoja y formara un caballón. Por el contrario, con la hoja perpendicular a la dirección de la marcha, solo se obtiene la extensión o reperfilado del material.

Nivelar y reperfilar un talud o una cara vertical (fig. 6.5.b)

Construir cunetas (fig.6.5c). La hoja vertedera se inclina, tanto en planta como respecto a la vertical, y se coloca de forma que sobresalga un poco de las ruedas, por el lado de la cuneta a excavar. Así se forma un caballón a lo largo del borde de la cuneta. Esta se va profundizando gradualmente por capas, manteniendo las ruedas interiores dentro la cuneta.

Rellenar de zanjas o desniveles (fig.6.5d.), La operación es similar a la que se realiza para formar un caballón.

Control de la hoja

Sin control, la hoja se orienta en el plano que determinan las irregularidades del terreno, pero como la hoja puede posicionarse mediante cilindros hidráulicos, el conductor puede imponer ciertas medidas de control, independiente de la posición que puedan adoptar las ruedas. No obstante, para conseguir superficies muy planas y regulares, es necesario utilizar algún dispositivo de nivelación. En las obras de carreteras, frecuentemente se instalan alambres a lo largo de la obra, y unos sensores instalados en la hoja controlan su altura automáticamente. Como solución alternativa, un rayo láser activa unas células fotoeléctricas que, a su vez, actúan sobre unos gatos hidráulicos; estos, situados entre la hoja y el chasis de la niveladora, se encargan de ajustar la posición de la hija vertedera.

Conclusiones

Con respecto a todo lo tratado anteriormente, en forma general se puede decir que este equipo es uno de los más indispensables al momento de trabajar en construcciones de movimiento de tierras en términos de acabado superficial, puesto que con la Motoniveladora se puede nivelar, modelar o dar la pendiente necesaria al material en que trabaja.

También, podemos mencionar su versatilidad la cual esta dada por los diferentes movimientos de la hoja, como por la serie de accesorios que puede tener.

La Motoniveladora es más frágil, ya que no es capaz de aplicar la potencia de movimiento ni la de corte del tractor, Debido a esto es más utilizada en tareas de acabado o trabajos de precisión.

La Motoniveladora también la podemos ver en trabajos de anexos al acabado superficial del terreno, por ejemplo, en la limpieza de nieve en caminos, para lo cual se adapta una pala en su parte delantera, que permite una limpieza ágil y oportuna en el lugar de trabajo.

Structures, Drawbar, Circle, Moldboard

Front Frame StructureContinuous top and bottom plate construction provides consistency and strength. The flanged box section design removes welds from high stress areas, improving reliability and durability, and increasing resale values for the customer.

Rear Frame StructureThe box-sectioned hitch design and cast axle mounting helps resist torsion loads and ensure structural durability. The integrated bumper ties the rear frame together as a single, solid unit, so the frame can withstand heavy-duty applications such as ripping.

Articulation HitchA large tapered roller bearing at the lower pivot carries loads evenly and smoothly. This joint is sealed to prevent contamination in this critical area. A mechanical locking pin prevents frame articulation to help ensure safety when servicing or transporting the machine.

Circle ConstructionOur one-piece forged steel circle is built to stand up to high stress loads and provide structural durability. The front 240° of circle teeth are hardened to reduce wear and ensure component reliability.

Drawbar ConstructionThe A-frame drawbar features a tubular design for high strength and optimum durability.

Aggressive Blade AngleWith a long wheelbase the operator can obtain aggressive moldboard angles so material rolls more freely along the length of the blade. This is particularly helpful when handling very dry materials or cohesive soils. Better material control gets the job done faster, requires less power and saves fuel.

Top-Adjust Drawbar Wear StripsThe patented top-adjust wear strips dramatically reduce drawbar/circle adjustment time. By removing the access plates on top of the drawbar, shims and wear strips can easily be added or replaced. This feature reduces service downtime and lowers overall machine operating costs.

Replaceable Wear InsertsTough, durable nylon composite wear inserts reduce rotational friction for maximum circle torque and longer component life. They are located between the drawbar and circle, and between the support shoes and circle. High load-resistant brass wearstrips are placed between the blade mounting group and moldboard. This sacrificial wear system can be replaced easily and helps keep components tight for fine grading.

MoldboardThe optimal curvature and large throat clearance help move material quickly and efficiently. Heat-treated moldboard rails, hardened cutting edges and end bits, and large diameter bolts assure reliability and longer service life. The moldboard side shift cylinder is positioned on the left side to eliminate snow wing interference.

Moldboard PositioningThe blade link bar design extends the possibilities for moldboard positioning, most beneficial in mid-range bank sloping and in ditch cutting and cleaning.

Shimless Moldboard Retention SystemThe unique shimless moldboard retention system reduces the potential for blade chatter. Vertical and horizontal adjusting screws keep the moldboard's wear strips aligned for precise blade control and dramatic reductions in service time.

Power Train

Smooth Shifting TransmissionThe 16M combines several key innovations to ensure smooth, powerful shifts throughout the gear range.

Electronically Controlled ShiftingThe full Electronic Clutch Pressure Control (ECPC) system optimizes inching modulation and smooths shifting between all gears and directional changes. This provides outstanding control and also extends the life of the transmission by reducing stress on the gears.

Engine Over-Speed ProtectionHelps protect the transmission and extend component life by preventing downshifting until a safe travel speed has been established.

Modular Rear Axle

The 16M incorporates a bolt-on modular rear axle design, which offers easy access to differential components, improves serviceability and contamination control, and lowers maintenance time and operating costs. The result is a rugged machine you can rely on for years to come.

Front AxleThe Caterpillar® sealed spindle keeps the bearings free from contaminants and lubricated in a light-weight oil (1). This durable, low-maintenance design reduces your owning and operating costs. Two tapered roller bearings (2) support the wheel spindle. The Cat “Live Spindle” design places the larger tapered roller bearing outboard where the load is greater, extending bearing life.

Gear SelectionEight forward and six reverse gears give the operator a wide operating range. The specifically designed range of gears ensures maximum productivity in all earthmoving applications.

Programmable AutoshiftThe operator can easily customize various shift parameters through Cat Messenger to match the specific application requirement. This optional feature automatically shifts the transmission at optimal points so the operator can focus on the work, improving safety, productivity and ease of operation.

Inching PedalAllows precise control of machine movements in any gear with low pedal effort and excellent modulation, critical in close-quarter work or finish grading.

Hydraulic BrakesThe oil bathed, multi-disc service brakes are hydraulically actuated (1), providing smooth predictable braking and lower operating costs. With brakes located at each tandem wheel, the 16M offers the largest total brake surface area in the industry (2), delivering dependable stopping power and longer brake life.

Automatic Differential LockThis standard feature automatically unlocks the differential during a turn, and re-locks once the machine is straight. A momentary override pedal can be actuated with the operator’s left heel if necessary. This helps make the machine easier to operate and provides additional protection to lower power train components.

Engine

ACERT™ TechnologyACERT Technology allows Cat engines to supply more power per unit of displacement without causing premature wear. This breakthrough technology reduces emissions during the combustion process by using advanced technology in the air and fuel systems, in conjunction with integrated electronics. ACERT Technology enhances overall engine performance while dramatically reducing exhaust emissions.

PerformanceThe Cat C13 engine meets specific performance requirements for 16M applications. Its superior torque and lugging capability can pull through sudden, short-term increases in loads, maintaining consistent, desirable grading speeds to get the work done faster without downshifting.

Hydraulic Demand FanThe hydraulic demand fan automatically adjusts cooling fan speed according to engine cooling requirements. This system reduces demands on the engine, putting more horsepower to the ground and improving fuel efficiency.

Exhaust Emissions CompliantThe Cat C13 with ACERT™ Technology meets or exceeds all U.S. EPA Tier 3 and European Union Stage IIIa emissions control standards.

Hydraulics

Advanced Electro-Hydraulic SystemThe 16M incorporates a state-of-the-art electro-hydraulic system. This technology is the foundation for revolutionary changes of the machine and implement controls. Advanced joystick controls provide unmatched controllability with precise, predictable hydraulic movements and the reliability you expect from Caterpillar.

Blade FloatBlade float is built into the blade lift control valves and is optional for some auxiliary hydraulic functions. The blade float feature allows the blade to move freely under its own weight. By floating both cylinders, the blade can follow the contours of the road when removing snow. Floating only one cylinder permits the toe of the blade to follow a hard surface while the operator controls the slope with the other lift cylinder.

Cat® XT™ HoseCaterpillar hose technology allows high pressures for maximum power and reduced downtime. Intelligent routing minimizes exposure to damage. Hose clips prevent hose rubbing and excessive vibration for lower owning and operating costs.

Independent Oil SupplyLarge, separate hydraulic oil supply prevents cross-contamination and provides proper oil cooling, which reduces heat build-up and extends component life.

Load Sensing Hydraulics (PPPC)The time proven load-sensing system and the advanced Proportional Priority Pressure-Compensating (PPPC, or “triple-PC”) electro-hydraulic valves on the 16M are designed to provide superior implement control and enhanced machine performance in all applications. Continuous matching of hydraulic flow and pressure to power demands creates less heat and reduces power consumption.

Balanced FlowHydraulic flow is proportioned to ensure all implements operate simultaneously with little effect on the engine or implement speeds. If demand exceeds pump capacity, all cylinder velocities are reduced by the same ratio. The result is improved productivity in all applications.

Consistent and Predictable MovementPPPC valves have different flow rates for the head (red) and rod (blue) ends of the cylinder. This ensures consistent extension and retraction speeds for each cylinder, and gives the operator a consistent and predictable response every time an implement control is moved.

Ether Starting AidThis standard feature helps cold-weather startups in extreme temperatures. The system monitors engine coolant temperature to prevent ether from being injected into a hot engine.

Structures, Drawbar, Circle and Moldboard

Front Frame StructureContinuous top and bottom plate construction provides consistency and strength. The flanged box section design removes welds from high stress areas, improving reliability and durability.

Rear Frame StructureTwo steel plates running the full length of the rear frame are integrated with the box section hitch. This helps resist torsion loads and ensure structural durability. The integrated steel tube unifies the rear frame and supports the engine, while helping the frame withstand heavy-duty applications.

Articulation HitchA large tapered roller bearing at the lower pivot carries loads evenly and smoothly. A mechanical locking pin prevents frame articulation to ensure safety when servicing or transporting the machine.

Drawbar ConstructionThe A-frame drawbar features a box-section design for high strength and optimum durability.

Circle Construction

A one piece forged steel circle is built to stand up to high stress loads and provide structural durability. Six bolt-on tooth segments can be individually replaced and serviced for reduced downtime and cost.

Replaceable Wear InsertsTough, durable wear inserts reduce rotational friction for maximum circle torque and longer component life. They are located between the drawbar and circle, and between the support shoes and circle. High load-resistant brass wearstrips are placed between the blade mounting group and moldboard. This sacrificial wear system can be replaced easily and helps keep components tight for fine grading.

Adjustable Rear Circle DriveAn adjustable rear circle drive makes serviceability easier and faster, and also reduces component wear by keeping components tight.

Yoke PlateFull-length yoke plate gives strength, support and protection to the circle.

Aggressive Blade AngleWith a long wheelbase the operator can obtain aggressive moldboard angles, so material rolls more freely along the length of the blade. This is particularly helpful when handling very dry materials or cohesive soils. Better material control gets the job done faster, requires less power and saves fuel.

MoldboardThe optimal curvature and large throat clearance help move material quickly and efficiently. Heat-treated moldboard rails, hardened cutting edges and end bits, and large diameter bolts assure reliability and longer service life.

Push Plate/CounterweightA front mounted push plate/counterweight can be added on the 24M.

RipperThe 24M standard ripper is made to penetrate tough material fast and rip thoroughly for easier material movement with the moldboard. The ripper includes three shanks with the ability to add four more if needed.

Hydraulics

Advanced Electro-Hydraulic SystemThe 24M incorporates a state-of-the-art electro-hydraulic system. This technology is the foundation for revolutionary changes of the machine and implement controls. Advanced joystick controls provide unmatched controllability with precise and predictable hydraulic movements, and the reliability you expect from Caterpillar.

Load Sensing Hydraulics (PPPC)The time proven load-sensing system and the advanced Proportional Priority Pressure-Compensating (PPPC, or “triple-PC”) electro-hydraulic valves on the 24M are designed to provide superior implement control and enhanced machine performance in all applications. Continuous matching of hydraulic flow and pressure to power demands creates less heat and reduces power consumption.

Consistent and Predictable MovementPPPC valves have different flow rates for the head and rod ends of the cylinder. This ensures consistent extension and retraction speeds for each cylinder, and gives the operator a consistent and predictable response every time an implement control is moved.

Blade FloatBlade float is built into the blade lift control valves. The blade float feature allows the blade to move freely under its own weight. By floating both cylinders, the blade can follow the contours of the haul roads. Floating only one cylinder permits the toe of the blade to follow a hard surface while the operator controls the slope with the other lift cylinder.

Variable FloatThe optional variable float feature lets the operator select the amount of down force the blade has when it is in float. This allows the operator to easily follow the contour of the haul road when removing only the loose material, increasing productivity and cutting edge life.

Balanced FlowHydraulic flow is proportioned to ensure all implements operate simultaneously with little effect on the engine or implement speeds. If demand exceeds pump capacity, all cylinder velocities are reduced by the same ratio. The result is improved productivity in all applications.

Cat® XT™ HoseCat hose technology allows high pressures for maximum power and reduced downtime. Intelligent routing minimizes exposure to damage. Hose clips prevent hose rubbing and excessive vibration for lower owning and operating costs.

Independent Oil SupplyLarge, separate hydraulic oil supply prevents cross-contamination and provides proper oil cooling, which reduces heat build-up and extends component life.

Safety

Operator Presence SystemThe Operator Presence System keeps the parking brake engaged and hydraulic implements disabled until the operator is seated and the machine is ready for safe operation.

Secondary Steering SystemThe standard secondary steering system automatically engages a ground driven hydraulic pump in case of a drop in steering pressure, allowing the operator to steer the machine to a stop.

Speed Sensitive SteeringThe steering software automatically provides an infinitely variable ratio between the joystick and the steer tires, resulting in less sensitive steering as the ground speed increases.

Low Sound and Vibration LevelsIsolation mounts for the cab, engine and transmission maximize operator comfort and help to minimize sound and vibration. These modifications provide a quieter and more comfortable working environment, optimizing operator focus.

Hydraulic LockoutA simple switch located in the cab disables all implement functions while still providing machine steering control. This safety feature is especially useful while the machine is roading.

Brake SystemsBrakes are located at each tandem wheel to eliminate braking loads on the power train. In addition, the brake systems are redundant and utilize accumulators to enable stopping in case of machine failure, further increasing operational safety.

Circle Drive Slip ClutchesTwo standard circle drive slip clutches protect the drawbar, circle and moldboard from shock loads when the blade encounters an immovable object. It also reduces the possibility of abrupt directional changes in poor traction conditions, protecting the machine, operator and surroundings.

Blade Lift AccumulatorsThis standard feature uses accumulators to help absorb impact loads to the moldboard by allowing vertical blade travel. Blade lift accumulators reduce unnecessary wear and help to avoid unintended machine movement for increased operator safety.

Rearview CameraVisibility is further enhanced with an optional Work Area Vision System (WAVS) through a 178 mm (7 in) LCD color monitor in the cab. Developed specifically for rugged applications, it improves productivity and increases operator awareness of surroundings.

Joystick Functions









Cat NOx Reduction SystemThe Cat NOx Reduction System captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.

Aftertreatment TechnologiesTo meet Tier 4 Interim/Stage IIIB emission standards and beyond, Cat aftertreatment components have been designed to match application needs. System components include a Diesel Oxidation Catalyst (DOC), which uses a chemical process to convert regulated emissions in the exhaust system, and a Diesel Particulate Filter (DPF) that traps particulate matter that is carried into the exhaust stream. The DOC, DPF and Cat Regeneration System are contained in a Caterpillar designed Clean Emission Module (CEM) that protects the components, minimizes the aftertreatment footprint and simplifies maintenance.

Cat Regeneration SystemThe Cat Regeneration System is designed to work transparently, without any interaction needed from the operator. Under most operating conditions, engine exhaust is hot enough to oxidize soot through passive regeneration. If supplemental regeneration is needed, the Cat Regeneration System elevates exhaust gas temperatures to remove soot in the Diesel Particulate Filter (DPF). This is a process that happens automatically, but the operator can initiate the cycle when convenient or interrupt regeneration as needed. A soot level monitor can be viewed on the Cat Messenger screen and regeneration indicator lights are integrated into the front console.Emissions Technology

Designed with Protection in MindFeatures are designed to enhance operator and job site safety, such as drop-down rear lights and a rearview camera. Among many standard safety features are laminated glass, back-up lights, and perforated tandem walkways and grab rails.

Operator Presence SystemThe parking brake remains engaged and hydraulic implements disabled until the operator is initially seated and the machine is ready for operation.

Secondary Steering SystemAutomatically engages an electric hydraulic pump in case of a drop in steering pressure, allowing the operator to steer the machine to a stop.

Hydraulic LockoutA simple switch located in the cab disables all implement functions while still providing machine steering control. This safety feature is especially useful while roading.

Brake SystemsBrakes are located at each tandem wheel to eliminate braking loads on the power train. Redundant brake systems utilize accumulators to enable stopping in case of machine failure, further increasing operational safety.

Circle Drive Slip ClutchThis standard feature protects the drawbar, circle and moldboard from shock loads when the blade encounters an immovable object. It also reduces the possibility of abrupt directional changes in poor traction conditions.

Blade Lift Accumulators (Optional)This optional feature uses accumulators to help absorb impact loads to the moldboard by allowing vertical blade travel. Blade lift accumulators help reduce unnecessary wear and also help reduce impact loading for enhanced operator safety.

Rearview Camera (Optional)Visibility is further enhanced with an optional Work Area Vision System (WAVS) through a 178 mm (7 in) LCD color monitor in the cab. Developed specifically for rugged applications, this durable camera improves productivity and increases operator awareness of surroundings.

Front and Rear Fenders (Optional)To help reduce objects flying from the tires, as well as build-up of mud, snow and debris, optional fenders can be added.Safety

Cat Regeneration SystemThe Cat Regeneration System is designed to work transparently, without any interaction needed from the operator. Under most operating conditions, engine exhaust is hot enough to oxidize soot through passive regeneration. If

supplemental regeneration is needed, the Cat Regeneration System elevates exhaust gas temperatures to remove soot in the Diesel Particulate Filter (DPF). This is a process that happens automatically, but the operator can initiate the cycle when convenient or interrupt regeneration as needed. A soot level monitor can be viewed on the Cat Messenger screen and regeneration indicator lights are integrated into the front console.Emissions Technology

Una Motoniveladora o Motoconformadora, es una máquina de construcción que cuenta con una larga hoja metálica (cuchilla) empleada para nivelar terrenos. Generalmente presentan tres ejes: la cabina y el motor se encuentran situados en la parte posterior, sobre los dos ejes tractores, y el tercer eje se localiza en la parte frontal de la máquina, estando localizada la hoja niveladora entre el eje frontal, y los dos ejes traseros. En ciertos países como Finlandia, la mayoría de las motoniveladoras están equipadas con una tercera cuchilla, localizada frente al eje delantero. La principal finalidad de la motoconformadora es nivelar y afinar bases y subbases de vialidades, asi como tambien patios y plataformas. Una de las características que dan gran versatilidad a esta máquina es que es capaz de realizar el refino de taludes con distintas inclinaciones.

La considerada mayor Motoniveladora del Mundo fue construida en 1980 por Humberto Acco, un contratista de Portogruaro, cerca de Venecia en el norte de Italia. Como no encontraba máquinas adecuadas para ciertos trabajos que tenia contratados se decidió a construirlas él mismo. Se construyo especialmente para una obra contratada en el desierto de Libia que finalmente no se comenzó por culpa del embargo Americano a Libia de 1980. La máquina se utilizó en algunos trabajos de explanación en Italia y esta plenamente operativa en las instalaciones de ACCO.Se construyó primero un prototipo y luego la máquina definitiva con algunas mejoras. Esta maquina pesa unas 200 Tm. y monta dos motores Caterpillar uno de 1000 CV. en la parte trasera y otro

de 700 en la delantera, la cual pertenece a la cabeza tractora de una mototrailla Caterpillar 657. La hoja (cuchilla) tiene una longitud de 10 metros.
