QUICK TAKE

Caterpillar is commercially introducing its Cat trolley assist system to the global market

Trolley assist is a system whereby a diesel- electric mining truck powers itself with electricity from overhead power lines instead of the diesel engine turning a generator onboard the truck.

This comes after the conclusion of a nearly two-year pilot project conducted with four 795F AC trucks using 700 m of electric trolley line Boliden’s Aitik mine in Sweden

By using trolley assist, speed- on-grade increases by as much as 100% versus diesel- only mode

The trolley system boosts productivity significantly – operating with trolley assist, speed-on-grade increases as much as 100% versus diesel-only mode

the mining markets that has operated trolley assist systems for more than 20 years, the technology has not caught on to the extent many expected. With mines continuously seeking for measures to stay on top of the cost

Powering a 337-t payload 795F AC via trolley on a 10% grade as it climbs the ramp out of the pit saves up to 40 ℓ of diesel fuel per kilometre of trolley line
