200kw / 250kw  Electrical Traction Coal Mine Machinery Shearer


Technical feature

This type of shearer is a new Electra Shearer, which is designed to suit the working faces with high productivity and efficiency in thinner coal layers. The body of the shearer is made of three parts: left traction, right traction and intermediate block. With the dovetail grooves wedge location and eccentric nut connection, the cool “going through” space is increased and the length of the machine body is cut down. This improving coal mining adaption, the bend ranging arms are selected, according to the design of 250kw, to provide with the cutting motors of 200kw or 250kw, the chainless traction system of rolling tracks have greater tractive power and stable operation, Application of AC on board speed regulating converter system, simple and reliable CPU control system can monitor and display the running conditions at any time. The radio remote control devices can be provided to realize off line operation. The main components of the valve sets and water circuit system are all centrally installed on the integrated blocks to guarantee less connecting points and simple maintenance. The height adjustment oil cylinder are designed to have almost horizontal arrangement, good pulling or pushing stress conditions and secured durability. The main electric components such as transvertors, controllers and bearing of driving systems are all imported from abroad. The viton rubber seals are used in the drives for longer service life of the machines.
