Shearer CLS550P

Designed for operation in thin and medium coal seams with changing hypsometry of 0.85-1.5 m.

Provides efficiency of up to 10 tons per minute.

Portal-frame shearer with box-shaped high-load frame to place feeding blocks and frequency converter.

The portal is designed in a way of separate bearing elements, rigidly connected with feeding frame and remote control assembling places.

Shearer length, including installed frequency converter, is 7.78 meters along the axes of cutting drums.

This positively affects on decreasing the coal-cutting with stone, which allows the customer to mine more “pure coal” with minimum rock content.

There used an imbedded contactless commutator between the rectifier and inverter, which excludes the DC links over-current and highly increases converter sustainability.

CLS550P is equipped with modern visualization software, which allows to control shearer operation in real-time mode, automatically calculate daily output, as well as analyse in details recorded data and figure out causes of efficiency decrease and equipment downtime.

CLS550P is fitted with modern control system that monitors main units load and automatically regulates shearer feeding speed. System controls main operational functions and allows to minimize shearer downtime (providing control automatization, mining recording, connection between shearer and other longwall equipment, transferring data to gateway and/or to the surface).
