REDUCING GREENHOUSE GAS EMISSIONS

Trolley assist offers mines the ability to reduce engine emissions and increase mine electrification. The reduction in diesel fuel consumption lessens greenhouse gases, NOx, and PM emissions. It promotes a more sustainable mining operation.

[+] More environmentally friendly mode of operation

[+] Between 20% to 60% reduction in CO₂ emissions

[+] Potential for carbon tax credits

increased PRODUCTIVITY

While connected to the trolley line, the Cat 795F AC can nearly double its speed. A recent study showed an increase of 100% speed-on-grade from 14 km/h (8.7 mph) to 28 km/h (17.4 mph). Putting over 4500 kW to the ground, the 795F AC (connected to trolley) is the Most Powerful Mining Truck in the World Today!

[+] Up to 100% speed-on-grade improvement vs. diesel mode

[+] 2x Faster Uphill

[+] Faster Cycle Times

REDUCE FUEL BURN, INCREASE ENGINE LIFE, REDUCE COSTS

The Cat trolley assist attachment operates at a higher voltage than most competitive trucks. The higher operating voltage significantly reduces electrical system losses in power transmission from the DC power lines to the wheel motors. This provides benefits such as lower infrastructure costs, reduced maintenance costs, and improved operational efficiency. When connected to the trolley system, the truck's propulsion system becomes powered purely with electricity from the power grid, minimizing the use of the diesel engine and maximizing the full potential of the wheel motors. Thanks to the significant decrease in diesel fuel burn while on trolley, engines are exposed to less wear and tear, thus increasing the engine's life until overhaul.

[+] 90%+ reduction in diesel fuel burn with trolley active

[+] Savings of up to 40 liters of diesel per cycle per 1 km of trolley line

[+] Increase machine engine life by up to 25%

100% caterpillar DESIGNED AND INTEGRATED

The Cat trolley assist attachment is the only one in the industry fully designed, integrated, and built to Cat specifications. The Cat trolley attachment leverages the 100% Cat-designed and integrated AC drivetrain. The attachment includes a purpose built and thoroughly tested trolley structure, pantographs, electrical wiring, hydraulic valve, electrical cabinet, and the necessary iron to fully integrate onto an electric drive mining truck. The ruggedized pantographs are designed to Cat specifications and work seamlessly with the rest of the attachment for optimal performance.    

[+] 100% Cat® integrated drivetrain optimizes performance & serviceability

[+] Reduced maintenance costs

[+] Validated structures deliver more uptime and lower repair costs

compatibility & Support

The Cat trolley assist attachment comes with the full support of the Cat dealer network. 100% of the trolley components have a Cat part number and are supported by the Cat parts network. A full set of operation, maintenance, and repair service publications are developed and published on the trolley attachment, and Cat dealers are trained and positioned to support the trolley system. Site infrastructure for the trolley system must be provided by a third-party.

The Cat trolley assist retrofit kit is currently available for the 795F AC truck. The trolley design is compatible with all other Cat ultra-class electric drive trucks (794 AC, 796 AC, 798 AC) – and will be available in the future.
