Abstract：In order to solve the problems of low reliability of 2800XPB shovel open bucket motor,such as non-self-winding and short service cycle of wire rope,combining the open bucket action and the working principle of electrical control system,the article analyzes the manifestations of actual faults on site,and upgrades and transforms the original open bucket device from high efficiency of bucket opening,low failure rate,maintenance free operation process,and problem of tangled steel wire ropes.The results show that the operation smoothness,wire rope life,energy consumption and failure rate of the modified open bucket system have been significantly improved,which not only improves the reliability and operation efficiency of the equipment,but also provides a strong guarantee for the smooth progress of mine production.
