The Clean Air Act

Cat battery-powered roof support carriers do not burden your mine’s ventilation with emissions or heat. Due to infinitely variable power control, they are the ideal vehicle for the installation or removal of longwall roof supports where heat, emissions and noise would impact work and where a flexible vehicle is needed.

The Power You Need

A combination of Cat battery- and diesel-powered vehicles can offer the ideal solution for longwall installations and moves. Battery-powered roof support carriers can position or remove roof supports from old and new faces.

Battery Power for Versatility

Cat battery-powered roof support carriers make longwall face moves simpler and less costly. The specially engineered ultra-heavy-duty vehicle range builds on the knowledge of many years of operational experience.

Stability and Traction

Cat roof support carriers have a tri-sectional chassis with dual motors located near the axles. The rear drive axle and the battery lift are incorporated into a single oscillating entity at the rear.

Battery Competence

Caterpillar has developed unparalleled experience and expertise in the design of batteries and battery changing systems. Current 2000 Ah batteries enable maximum performance at peak loads as well as lasting performance throughout the shift.

Maximum Battery Efficiency

The Cat IGBT control makes the most of battery power.

Optional VFD

The latest Caterpillar innovation is the HiPAC 10 VFD control system, which drives the motive traction and hydraulic systems and provides the operator with machine management information. The HiPAC 10 is a DC-to-AC variable frequency inverter control that drives high-performance AC electric motors, which have superior speed-torque characteristics.

RAS - Rapid Attachment System

The Rapid Attachment System available for the CL10 and CL15 makes an accessory change a one-man operation, allowing a broad range of accessories to be fitted in moments without removing the backing plate. Utilizing the LHD with RAS attachments during longwall relocations can greatly reduce lost production time.
