Abstract

According to the high efficient need of hard coal complicated conditions,MG500/1140-GWD electric haulage shearer was developed on the previous similar products. The shearer adopts the new type cast material ZG25Mn2 II,while improving the cutting part,haulage part and gear transmission system design,reduce the cutting part volume and haulage part volume in order to increase 18% coal space,improve roller torque to 175 k N·m,the haulage force was increased to 800 k N,improving the coal shearer climbing and crossing ability; using the imported mature elements and many patents,During the coal mine working,running smoothly,high yield and high efficiency.
