Designed for operation in thin and medium coal seams with changing hypsometry of 1.05-2.4 m.

Provides efficiency of up to 15 tons per minute.

Shearer is made with block construction and placing main units in frame, which ensures an easy access to units for service support and simplifies assembling/dismantling.

The amount of cables required for shearer operation was decreased by using the feeding speed regulating variable-frequency drive, mounted into shearer main frame, while all main units – above the AFC. Therefore, there is no need to purchase additional gateway equipment.

Shearer length, including installed electric equipment, is 8.1 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.

CLS450 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.

CLS450 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).
