Growing a portfolio of electrified machines
Recent efforts to electrify machines are delivering significant gains in efficiency―and significant reductions in exhaust emissions.
One of the best ways to reduce emissions is to minimize fuel usage. Our diesel-electric products help in that effort. We offer a number of diesel-electric machines for mining — like the 794, 796 and 798 AC trucks; R2900 XE underground loader; and 988K XE wheel loader. Large dozer electrification projects are in currently in progress. In some applications, diesel-electric machines operate more efficiently and burn from 5 to 25% less fuel for reductions in emissions of the same amount.
Our fully electric machines rely on a single non-engine power source and produce zero exhaust emissions.
Some electric machines such as Cat Electric Rope Shovels are tethered to a power source. Not only do our electric rope shovels produce zero emissions, they also actually regenerate power that can be reused or delivered back to the power grid. In addition a number of electric Cat Rotary Drills are either in production or soon to be commercially available.
Battery-powered vehicles like the new R1700 XE underground loader are also fully electric but are not tethered to a power source. Thanks to a mobile fast charging system called the Cat MEC500, the battery electric R1700 can be charged anywhere there is access to the mine’s power grid. Depending on the mine’s infrastructure, the battery can be charged in as little as 20 to 30 minutes.
We continue to leverage our expertise and are committed to building a broader range of electrified products that build on the legacy of our current offerings.
A trolley assist attachment for Cat trucks allows the machine to make use of external power during a certain section of the haul road. When connected to the trolley system, the truck’s propulsion system is powered purely with electricity from the power grid ― reducing fuel burn by more than 90%.
- Boosts productivity: Up to 100% speed-on-grade improvement when connected to the electric grid
- Reduces emissions up to 60%: Truck is powered by the electric grid during sections of the haul road
- Improves engine life up to 25%: Decrease in diesel fuel burn reduces wear and tear
- Compatible with Cat ultra-class electric drive trucks
