Deck always provides firm footing without the obstacles of rock on the ground
Deck Entrance and ladder design allows the operator to easily exit the deck area
Scaled material falls away from the operator
MacLean Bolter Proven Safety
Operator can easily sound and scale rock conditions following the 5 rules of scaling and sounding:
RULE #3: SCALE FROM GOOD GROUND TO BAD GROUND
Natural progression of bolting from deck ensures operator is always under supported ground
RULE #4: WATCH FOR UNEXPECTED FALLS
MacLean Bolter Proven Safety
Operator can easily sound and scale rock conditions following the 5 rules of scaling and sounding:
