However, the mine owner should be concerned with Empty Vehicle Weight
(EVW) of haul trucks.
Machines powered by the new-generation diesel engines also provide higher productivity, better torque, less downtime, lower fuel consumption, reduced heat signatures, and optimized payload per envelope size and empty vehicle weight
ratios, according to Sandvik.
The empty vehicle weight
increased to accommodate the larger AC traction motors, front suspension and steering system components required for the larger 63 in tyres.
Payload (Gross Vehicle Weight (GVW) minus Empty Vehicle Weight
(EVW) equals Maximum Payload) follows the 10/10/20 rule; often misunderstood, the rule means no more than 10% of loads may exceed 10% above target payload and no loads may exceed 20% above target payload.
