Shearers

The shearer is the heart of your longwall operation, working around the clock to cut away the face and keep the whole system productive. High installed power and machine mass for the toughest cutting conditions

MORE UPTIME 
Redundancy and high factors of safety in the design of the machine ensure maximum reliability

PROVEN RELIABILITY:

  • Designed redundancy for maximum uptime
  • Modular mainframe concept for maximum protection of gearboxes and flameproof enclosures
  • High machine weight to cope with the toughest cutting conditions

We offer a number of shearer models to suit seams ranging from 1.6 to 5.5 m (63 to 217 in).

Plow Systems

For small and medium seams, a plow system can be less expensive and more productive than a shearer. Cat plows offer record-setting production in a compact, durable frame. With unmatched power and precise control systems, these machines are a cost-effective alternative for many mines. In coal seam heights below 1.8 m (71 in), the plow is more productive than a shearer.

Caterpillar offers plows for seams ranging from 0.6 to 2.3 m (23.6 to 90.5 in).

Roof Supports

Cat Roof Supports

Everything depends on your roof supports. The safety of your people and the continued production of your operation are constantly threatened by the difficult conditions of the seam.

Steep inclines, varied rock thickness and soft ground all make for unpredictable conditions, and you need a roof support system that can overcome them all. Cat roof supports are customized to meet your specific needs, with advanced automation, personnel proximity detection and more. And they’re built to last, offering a lifetime of up to 90,000 cycles.

CST Gearboxes

Cat CST Gearboxes

In high-performance longwall mining, the conveyor system must adjust quickly to carry huge loads and respond to load changes. Cat CST drive systems provide intelligent features like no-load motor startup, AFC soft start and synchronized heavy-load startup to allow accurate load-sharing between up to three drive motors with excellent, extremely fast overload protection.

Cat Longwall Automation

Automation is an integral part of a modern longwall mining operation, allowing the system to work safely and productively around the clock.

Ensuring that every piece of equipment is connected and communicating quickly and reliable is critical, and that’s where the Cat® PMC family of Programmable Mining Controls comes in. All PMC controls are intrinsically safe, and connect to each other to form a fast, stable network of communication and control. Every PMC control allows operators to control the function of its corresponding machine, as well as handling automation and data collection.

VR Services

Longwall mining requires a great deal of in-depth, upfront training for operators and service personnel. Longwall mining systems are complex, and in order to operate them safely and productively, operators need hands-on experience.

However, the full system is not always available or operational when operators need to be trained. And once the system is installed and operational, it can be difficult to find time and access to adequately train new personnel without dramatically affecting production. This can be mitigated by video or instructor-led training, but these methods just aren't as effective as hands-on, in-the-iron education.

Caterpillar offers realistic, interactive 3D simulations that can help your operators gain necessary knowledge and experience safely and efficiently.
