Trolley assist added for Cat electric drive mining trucks

Caterpillar introduces trolley assist for Cat electric drive mining trucks

Cat has released a trolley assist system for electric drive mining trucks for mining operations seeking a means to reduce carbon emissions, lower fuel and engine costs, and boost speed-on-grade for greater productivity. 

The Cat trolley assist retrofit kit is currently available for the 795F AC truck, and the trolley design is compatible with the three other Cat electric-drive mining trucks—794 AC, 796 AC and 798 AC.

The commercial introduction of Cat trolley assist comes at the conclusion of a nearly two-year pilot project conducted with four 795F AC trucks using 700 metres of electric trolley line at Boliden's Aitik mine in Sweden.

Trolley steps up

The trolley system significantly reduces diesel engine emissions at the mine via substitution of electricity during the most demanding part of the truck work cycle. Powering a 337-mt-payload 795F AC via trolley on a 10 percent grade as it climbs the ramp out of the pit saves up to 40 litres of diesel fuel per kilometre of trolley line. Fuel and engine costs are reduced by more than 90 percent while the truck is on trolley.

The trolley system also boosts productivity. Operating with trolley assist, speed-on-grade increases as much as 100 percent versus diesel-only mode. Using trolley, a loaded 795F can run at 28 kph on a 10 percent physical grade with solid haul road conditions.

The Cat trolley system is fully machine integrated, bringing the benefits of optimized performance and system serviceability to the 795F AC. Caterpillar's higher voltage truck and trolley system is designed to bring advantages through lower infrastructure capital costs and lower power distribution maintenance costs.

Other advantages come from the rugged Cat pantograph, designed to deliver superior uptime and reduced repair costs. A quick-drop feature helps protect the overhead trolley lines.

LOAD 60 TONS IN JUST FOUR PASSES WITH VOLVO

A bottleneck of haulers waiting to be loaded is inefficient. Idle machines burn unnecessary fuel, increase maintenance costs and decrease resale values when you're ready to trade them in.     

When you pair the new Volvo EC950F crawler excavator and A60H articulated hauler, you can load trucks faster. The EC950F can utilize a 10-yard bucket to fill a 60-ton capacity A60H in only four passes — reducing passes lowers fuel consumption and drastically speeds up cycle times to keep your haulers moving. See how the massive EC950F and A60H improve cycle times and more to boost your profitability.
