Haul trucks use external 电al power during uphill road segments
A trolley-assist system for diesel-电 haul trucks utilizes a diesel engine to drive an alternator that produces energy to power 电 wheel motors.
When the trolley-assist mode is engaged on diesel-电 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 电al power drawn to move the haul truck is generated from a cleaner source than that of the diesel engine while also improving fleet productivity.

Trolley-Assist Inquiry
A trolley-assist system for diesel-电 haul trucks utilizes a diesel engine to drive an alternator that produces energy to power 电 wheel motors. When the trolley-assist mode is engaged on diesel-电 haul trucks, the diesel engine is bypassed entirely, and power consumption is redirected to the draw from overhead lines.
Haul trucks use external 电al power during uphill road segments. The intention for trolley-power is that the 电al power being drawn to move the haul truck is generated from cleaner source than that of the diesel engine.
Ideally trolley should be included in early mine planning to optimize system. Simulation with life of mine trolley assist scenarios helps pre-plan long term system modification. Experts and consultants are available to assist with planning.
There are infrastructure, 组件, and design requirements to consider before implementing a trolley-assist system.
- 悬链线系统
- 牵引变电所
- Illumination of catenary system
- 信号
- 受电弓包
Attractive payback periods of 2 – 4 years after initial investment. System maintenance is required but is offset by reduced engine maintenance. System is flexible and can be moved, extended, shortened or otherwise modified for the application.
