The new Caterpillar (Cat) R1700 XE LHD, with its 15-metric-ton (mt) payload and 24,190-kg lift and tilt breakout, features a battery electric design and offers an 18 km/h top speed. An Autodig function optimizes loading and traction control to extend tire life. Liquid cooling allows the batteries to be cooled while the machine is put back in operation, increasing machine uptime availability.
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.
Cat sees the new R1700 XE LHD is a key part of the vision to an all-electric mine. It is the first battery powered/zero emissions equipment for the company’s LHD (Load Haul Dump) product line and offers remote control operation capability. The MEC500 is designed to charge quickly and safely wherever it is needed. Unlike static charging stations, the 1,600-kg portable charger can be moved to where it is needed via towing, fork truck, or the R1700 XE. It eliminates the need for regular battery handling and swapping, allowing for more efficient charging and production.
Its 500-kW capability delivers 300-1,000 volts and up to 700 amps. Its adjustable output voltage and current can trickle charge the battery, maintaining optimal performance for the RX1700 XE. The charger is built rugged meeting ISO2867 rockfall protection and IP66 rating for water and dust protection.
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.
