New Cat D11 XE dozer at MINExpo
Caterpillar’s new D11 XE dozer with electric drive has made its debut at the MINExpo 2021, happening right now. The D11 XE dozer’s electric drive system is said to deliver constant power to the ground, continuous pushing and greater manoeuvrability for faster cycle times and improved fuel efficiency.
Cat says the D11 XE offers the lowest cost per ton operation in dozing applications. When in production, this Cat model will be the world’s largest, most powerful and efficient electric drive dozer with high drive. The D11 XE targets up to 25% less fuel costs per BCM, while the new design brings up to 20% longer engine rebuild cycles than mechanical drive models, while 60% fewer moving parts translates to better machine uptime availability.
The D11 XE fully integrates Cat powertrain, Cat electronics, Cat software and Cat controls for optimised performance. Inherent machine protection reduces component damage for improved reliability. Its updated electronics architecture allows the dozer to take advantage of Cat technologies like MineStar Command for dozing, which offers both remote control and semiautonomous dozing.
The new dozer’s modular design simplifies maintenance through improved serviceability of the powertrain. Fewer moving parts translates to fewer touches required to maintain the dozer and lower service costs. This electric drive dozer also shares components with mechanical drive models, meaning familiarity for service technicians and fewer parts to stock for owners.
With a powertrain life targeted to deliver longer rebuild intervals, the simple machine design delivers less major component rebuilding and/or replacing. Longer rebuild cycles, lower fuel consumption and less maintenance come together with higher machine efficiency to give owners the lowest cost of bank cubic meters (BCM) of material moved ever.
The D11 XE is currently operating at Caterpillar’s dozer proving grounds in Peoria, Ill., and will then complete an extensive field validation plan before entering full production.
