Trolley-Assist Truck Haulage is a haulage system which utilises diesel-electric haul trucks and then directs grid-based electrical power directly to the truck via an overhead catenary or “trolley-line” in much the same way as a city tram. As a result of this approach The systems are primarily installed on pit and dump ramps, where the
Longer hauls and steeper grades present an opportunity for trolley assisted haulage. Typical truck payload requires a huge power source (around 2,200 kW) that has to be efficiently used. Keeping the gross vehicle weight for haul trucks as low as possible is also important, so power consumption is limited to just ore transport.
Trolley-assist haulage was never popular because of pit layout limitations and inflexibility, but it was used successfully at a few mines around the world. Yet, the concept of electric wheels did become popular in large vehicles, continuing to be the drive of choice for the largest haul trucks in
