Cat to bring new D11 XE dozer, R1700 XE battery-electric LHD to MINExpo

Vital to the vision of the all-electric underground mine of the future, the new Cat R1700 XE LHD will feature 100% battery-electric propulsion that generates significantly less heat and noise. It offers a 15t payload, 24,190 kg lift and tilt breakout force, and 18 km/h top speed. To optimise runtime and improve safety, batteries stay on the machine for charging, with the new portable Cat MEC500 Mobile Equipment Charger able to charge the unit in as little as 20 minutes.

For Worldwide Release: June 2021

Underground mining continues to be an early adopter of sustainable mobile equipment solutions, based on the need for a clean and safe working environment. The new Cat® R1700 XE LHD, with its 15-tonne payload and 24,190-kg lift and tilt breakout, features a battery electric design that delivers superior productivity in underground applications with the benefits of no engine heat or exhaust emissions. It offers an 18 km/h top speed.

To maximize runtime, batteries stay on the machine. Using the portable Cat MEC500 Mobile Equipment Charger, the R1700 XE can be fully charged in less than 30 minutes using a single charger or in less than 20 minutes using two chargers.

MINExpo 2021 attendees will get a first look at the R1700 XE and MEC500 this September in the Caterpillar Central Hall exhibit 6229 at the Las Vegas Convention Center.

For Worldwide Release: September 2021

In support of our customers’ goals for reduced carbon operations and leveraging over 400 Caterpillar advanced power system design patents, the new electric Cat® R1700 XE LHD offers 100% battery-electric propulsion, producing zero exhaust emissions and significantly less heat generation than a reciprocating engine powered model for underground mining operations. The new underground LHD matches the performance of the diesel-powered R1700 while using switch reluctance (SR) technology that draws from Caterpillar’s more than 15 years of electric drivetrain experience and thousands of field application operating hours.

Featuring fast onboard charging technology, the machine’s batteries can be charged while remaining on the R1700 XE to maximize available run time. The portable Cat MEC500 Mobile Equipment Charger provides quick charging wherever it’s needed and eliminates the expense of and need for static charging station infrastructure, additional batteries, and battery handling and swapping. The MEC500 fully charges the R1700 XE in less than 30 minutes using a single charger or in less than 20 minutes using two units. Liquid cooling allows the loader’s batteries to be cooled while the machine is put back in operation, increasing machine uptime availability.

Borrowing the front linkage geometry from the R1700, the R1700 XE offers matching lift and tilt breakout force for electrified machines of 24 190 kg (53,330 lb). Advanced hydraulic performance and load-sensing pumps with controllable flow deliver a 13.2-second raise/dump/lower hydraulic cycle time and 323 kN (72,613 ft-lb) rimpull and drawbar. The electric LHD vehicle offers 15 tonnes (33,069 lb) payload, 18 kph (11.2 mph) fully loaded top speed and 2.5 hours of aggressive run time between charges.

Five bucket sizes, including a bolt-together bucket option, with capacities ranging from 5.7 to 7.5 m3 (7.5 to 9.8 yd3) match material density needs to various loading, hauling and dumping conditions. Offering optimized balanced between productivity and bucket life, the full range of Cat ground engaging tools (GET) includes modular Weldon, bolt-on half arrow, and Durilock™ mechanically attached shrouds, heal shrouds and wear plates.

The Cat R1700 XE underground battery-electric LHD on display at MINExpo 2021 will be commercially available in select markets starting in the first quarter of 2022.
