Longer Overhaul Interval

In addition to offering features that deliver superior performance, Cat continuous miners offer a whole range of engineering features that contribute to long, reliable service between overhauls.


Efficient Cuts

Infinitely variable tram control allows precise control of steering, speed and traction with independent control of the two sides. This high maneuverability allows faster positioning and optimum cutting, increasing productivity.


Weight

Cat continuous miners use a 75 mm steel plate for the main frame – 50% thicker than competitors.


Ease of Operation

Caterpillar offers a Machine Control Unit designed to operate the entire Cat continuous miner. Based on a mine-duty PLC, this drive and control system combines maximized coal production and operator safety with minimum downtime.


New Generation Controls

Caterpillar has ongoing development aimed at providing mining operations with reliable controls to the level of complexity that fits their needs.


High Availability, Low Maintenance

The dimensioning of components and structural elements – such as motors, pumps, clevises and pivots – and their location and packaging ensure ease of maintenance, increase machine availability and reduce operating costs. Cat continuous miners are built to last.


Ease of Maintenance

Cat continuous miners are designed to facilitate maintenance, which in turn cuts costs and increases availability and productivity. Unlike our major competitor, the cutter head gearcases on Cat machines are independent.


Commonality of Parts

The CM220, CM230 and CM240 have common components such as gathering head gearboxes, conveyor motors, tram motors, tram gearboxes, electrical boxes, radio control system, hydraulic pump, pump motor and crawler chain assemblies. The major common components of the CM330, CM340, CM345 and CM430 are the gathering head gearboxes, conveyor motors, tram motors, tram gearboxes, radio control system, hydraulic pump, pump motor, cutting head gearbox and crawler chain assemblies.


Motors

Motors are designed for heavy-duty 50 Hz operation so as not to compromise power, speed or production. Overheating and failure of these powerful motors is prevented by electronic motor overload protection.


Robust Gear Cases

The robust gears are made from carburized high-alloy steel with ground teeth for accuracy and quiet operation. The replaceable cutter head input gear cases allow quick and economical replacement of the components most susceptible to failure due to inadequate lubrication.


Low Overhaul Frequency

The overhaul interval is maximized by various measures to reduce wear and tear. All major wear areas – including spade, conveyor and cutter gear case webs – have long-life 13 mm Chrome Carbide Overlay (CCO) liners.


CM845 Standard Equipment

• Heavy main frame for rigidity and stability

• Independent tramming for maneuverability

• Wide conveyor for maximum loading rates

• Wide crawlers for maximum penetration and low ground pressure

• Radio remote with self diagnostics available

• Easy access and low maintenance

A Commitment to the Mining Industry

As the demand for commodities grows, mining companies need a partner to support them in their efforts. Caterpillar is committed to being that partner.
