Caterpillar released the trolley assist system for their electric-drive mining trucks. Currently available for the 795F AC truck as a retrofit kit, the solution aids in reducing carbon emissions, lowers fuel and engine costs, and boosts speed-on-grade for greater productivity, the company reported.
The solution reduces engine emissions at the mine via substitution of electricity during the most demanding part of the truck work cycle, Cat reported. Powering a 337-metric-ton (mt)-payload 795F AC via trolley on a 10% grade as it climbs the ramp out of the pit saves up to 40 liters of diesel fuel per kilometer of trolley line. Trolley assist was trialed at Boliden’s Aitik mine in Sweden, where it helped up both availability and speed-on-grade, leading the miner to deploy it more broadly.
