Face conveyors in modern high-performance longwalls have to move enormous loads while withstanding huge load changes. Cat® CST drive systems transmit drive forces of over 1 200 kW (1,950 hp) per drive — safely, reliably and in a way that protects the system. They make optimum use of power, synchronize motors and drives on both the main and auxiliary drives, and prevent unnecessary load changes.
With extensive automation technology and a patented clutch, CST offers a series of benefits over conventional drives.
- No-load motor start-up with modest energy demand on the electrical system
- Soft start of the face conveyors, which is gentle to all components, particularly the chain
- Maximum total torque of up to 3 x 200 kW / 1,195 hp to facilitate heavy load start-up of the fully loaded conveyor
- Accurate load sharing between the drives for full utilization of the installed power
- Excellent overload protection in the event of sudden chain jams
- Closed system, oil cooling via heat exchanger
- Clutch that delivers maximum efficiency with minimum operational slip of 0.2 percent with no wear
