SH680^Non-Current

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 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.

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.

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 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.

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

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.
