MG65/147-D A.C. Electric Traction Shearer

 

MG65/147-D A.C. Electric Traction Shearer

      1. Purpose and use scope：

MG65/147-D A.C. electric traction shearer is suitable to exploit the mining coal bed thickness from 0.75-1.6 meter, hardness of the coal bed is medium-hard or less than it.

MG65/147 - D type ac traction shearer and hydraulic support are allowed to be used in mines with coal dust and gas explosion hazard.

MG65/147-D A.C. electric traction shearer conforms the request of "Coal Mine Safety Regulation", its designing drawing and the prototype has passed through the  auditing and the explosion-proof experiment by the Coal Academy of Science.

2. Capability characteristics：

MG65/147-D A.C. electric traction shearer is the exclusive double-ended power chain-hauled shearer at present in China, which can be used for thinnest coal bed, all the electric machine is horizontal arrangement, no underframe, chain-hauled part is a whole cabinet, two cutting parts on left and right are symmetrical structure,  inside parts are common use, use bent rocker arm so as to increase space; chain-hauled transmission.
