CM340 - Continuous Miner
The CM300 Series ranges from the mid-seam CM330 to the CM345 for narrow pathways and the CM845 miner bolter. These miners have maximum cutting heights ranging from 3.1 m (122 in) to 4.6 m (181 in).
|Mining Range||1.37-4.00 m (54-158 in)|
|Weight||70 tonnes (155,000 lb)|
|Total Power||697.0 kW|
Longer Overhaul IntervalIn 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 CutsInfinitely 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.
WeightCat continuous miners use a 75 mm steel plate for the main frame - 50% thicker than competitors.
Ease of OperationCaterpillar 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 ControlsCaterpillar has ongoing development aimed at providing mining operations with reliable controls to the level of complexity that fits their needs.
- AC VFD (Variable Frequency Drive) or DC Drive Options
- Integrated electronic overloads
- Color graphic diagnostic options
- Data logging
- Smart Hydraulic System
High Availability, Low MaintenanceThe 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 MaintenanceCat 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 PartsThe 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.
- Lower cost of inventory and higher parts availability
- Faster replacement
- Trained technicians can fix any machine in series
- Flexibility: for example, the CM230 can be converted into a CM220
MotorsMotors 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 CasesThe 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 FrequencyThe 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.
- 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
