GVW BelAZ. El camión de carga másgrande del mundo es eléctrico

La mayor parte de la gente cuando piensa en un vehículo eléctrico, piensa en un cochepequeño y sencillo que apenas puede mover su propio peso. Pero los motores eléctricos han

ido mucho más allá, y como ejemplo tenemos al impresionante camión de carga GVWBelAZ.

Todo lo que rodea a este monstruo sobre ruedas son cifras apabullantes. Cuenta con un

cuerpo de 20 metros de largo y 360 toneladas de peso. Para moverse utiliza cuatro

motores Siemens de 1.200 kW…cada uno. En total 4.800 kW (6.528CV). Para alimentar

estos cuatro mastodontes eléctricos, el GVW cuenta con dos generadores gasolina de 16litros y 1.700 kW.

Esta configuración le permite moverse hasta una velocidad máxima de 64 km/h cuando

está vacío, y transportar hasta 450 toneladas de peso en cada viaje. Una cifra equivalente a

la de un Airbus A380, y que supone mejorar un 25% la capacidad de los modelos de la

competencia.

Entre los puntos más interesantes del sistema de tracción total eléctrica, está que el

conductor puede contar con una distribución de la tracción dinámica. Esto le permiteadaptar las necesidades de potencia en cada eje en tiempo real, algo muy importante en las

difíciles condiciones en las que tienen que trabajar estos gigantes.

Otro de los aspectos que más valoran sus propietarios es la fiabilidad. Los motores

eléctricos se Siemens permiten disfrutar de un nivel de productividad elevado. Por ejemplo,

el GVW BelAZ puede seguir trabajando incluso con uno de los motores eléctricos

averiados. También importante es la cada vez mayor presión de las leyes de emisionesdentro de las minas cerradas. Un aspecto que hace que este tipo de modelos ganen terreno.

No queremos imaginar el ahorro económico de lograr hacer funcionar exclusivamentecon electricidad a estos monstruos. Ya sea con una mastodóntica batería, o mediante un

sistema que la propia Siemens está probando en Suecia, y que traslada la idea del

pantógrafo de los tranvías al transporte en carretera.

Zhodino, Belarus 

On the 25th

 of September, BELAZ celebrated its 65th

 anniversary. The customers,dignitaries, suppliers and special guests witnessed the unveiling of three new products: a90mt (100) electric drive truck, a remotely controlled 136mt (150) truck and the world’s

largest capacity mining truck, the 450mt (500) model 75710. All three trucks were

available for hands-on inspection and in-operation viewing at the BELAZ engineering test

facility.

Datos Técnicos

The 75710 was designed at the request of long time BELAZ customers. Those customersoperate trucks ranging in capacity from 130 to 360 metric tons. They demanded that the

75710 incorporate all of the design characteristics of their current trucks

•  Excellent performance and reliability provide by high performance engines fromleading manufacturers, AC electric drive systems and efficient body hoist systems

•  Good maneuverability and superior ride comfort based on optimal integration of the

truck and steering system and application of the innovative BELAZ designed

pneumohydraulic suspension.

•  Operator safety and comfort with a modern cab, hydrostatic steering, and a high-

performance electrodynamic retarder.

•  Long service life as a result of using advanced propulsion systems, latest technology

components and assemblies and high strength materials in the frame and body.

Through a combination of unique designs and engineering innovations, the BELAZ product

development experts were able to incorporate the traditional BELAZ truck characteristics

into a hauler capable of carrying 450 metric tons of material and operating in the same

footprint as its 320mt and 360mt predecessors. The model 75710 is designed to present acompact profile, achieve a significant performance increase and meet world safety

standards.

Unique design features include:

• 

450mt payload capacity by using 8 tires•  Excellent maneuverability by using two pivoted axles and BELAZ engineered

steering kinematics. The turning radius of the 75710 is 19.8 meters. (Turning radius

of a 360mt capacity truck is 17.2 meters)

•  Perfect stability without sacrificing ride comfort due to use of anti-roll bar struts inthe suspension system

•  The ability to operate at or near rated capacity in high rolling resistance

environments through the standard all-wheel drive configuration.

•  Superior dumping performance with power enhanced hydraulic hoist drive

•  Optimized fuel efficiency by operating only one of the two engines when the truck

is not loaded.

• 

High performance, reliability and safe operation are provided by a “smart” ACelectric drive system with electronic differentials and antiskid system

Performance characteristics of the 450mt truck are impressive: The ability to climbprotracted longitudinal grades to 14% and short slopes up to 18%. Maximum truck speed of

64km/h. Resistance to “bogging down” or reducing payloads is very wet or unstable soilconditions.

25% Productivity Gain: As a result of its innovative design and unique features the

BelAZ-75710 is estimated to provide a productivity gain of 25% versus the largest capacity

trucks currently in use.

Discussions are being held with a number of customers to determine where the truck will

make its debut in the dirt. Field trials are ready to begin. The sale of trucks will begin

during 2014.
