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 Clean Air Act

As the world leader in battery-powered vehicles and longwall systems for the underground mining industry, we take pride in providing the world’s most advanced battery-powered roof support carriers. Innovative solutions in power control and transmission contribute to utilizing battery power to the max.

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.

The Power You Need

The operator benefits from their superior versatility, tight cornering, tractive effort control and maneuverability on uneven ground. Battery-powered vehicles do not negatively impact the working environment with emissions or noise.

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.

Battery Power for Versatility

The electric drive concept gives operators the best control of power and maximum torque capabilities at low speeds. Zero emission of noxious gases and low emissions of heat and noise make the carrier range operator-friendly and easy to work with. They are the ideal utility vehicle for longwall moves.

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.

Stability and Traction

This gives the carrier extra stability, even when handling loads equal to the empty vehicle weight. As load motion is independent of the rear frame, this design provides extra load handling stability, especially on uneven ground or while maneuvering and positioning roof supports. It also improves traction, as wheels remain in contact with the ground with the weight of the battery over them.

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.

Battery capacities and vehicle designs are field-proven and are adapted to actual work schedules and longwall move experience. The Cat East Penn battery is built for the long run, providing the lowest cost of ownership in the industry. Specially formulated premium-grade lead oxide is used in the flat plate design and each plate is individually formed prior to cell assembly. This ensures uniform performance and maximization of amp-hour capacity. State-of-the-art computerized equipment is utilized in every phase of the production process and stringent quality checks are made on each battery to ensure the highest level of performance.

Maximum Battery Efficiency
The Cat IGBT control makes the most of battery power.

It translates to variable speed and tractive effort at the varying intervals. This allows battery power to be controlled with maximum precision and efficiency.

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.

It is up to 14% more efficient than traditional DC motors. This means higher loaded tram speeds, more responsive hydraulic functions and more material hauled per battery charge. The HiPAC 10 machine management system speeds fault diagnosis, allowing rapid repairs and maximizing uptime. The new user interface can display information such as drive unit temperatures and distance traveled per battery charge. The optional Cat control stick gives the operator intuitive control over steering and other functions. It also gives quick access to monitoring and self-diagnosis of the vehicle’s functions.

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.
