Haul trucks use external electrical power during uphill road segments
A trolley-assist system for diesel-electric haul trucks utilizes a diesel engine to drive an alternator that produces energy to power electric wheel motors.
When the trolley-assist mode is engaged on diesel-electric haul trucks, the diesel engine is bypassed entirely, and power consumption is redirected to the draw from overhead lines.
The advantage of trolley-power is that the electrical power drawn to move the haul truck is generated from a cleaner source than that of the diesel engine while also improving fleet productivity.
