Time:2016-8-4 Clicks:2206All personnel engaged in the excavator industry are familiar with crushing hammers, not only because the wages of crushing operations are higher, but also because the risk and difficulty coefficient of crushing operations are higher than those of ordinary operations. For the driver, the three points of selecting, striking and maintaining the hammer are the basic skills. However, in actual operation, the hammer is often broken and the maintenance takes a long time......
Time:2019-6-14 Clicks:21431、 The hammer has no strength? The cause is nonstandard operation. When the crushing hammer is empty, the piston transmits the impact force to the steel drill rod, and the steel drill rod transfers the impact force to the steel drill pin. The steel drill pin is easy to break when it bears a strong impact force. When the steel drill pin is impacted, the impact force will be distributed back and forth to the steel drill pin cross pin. At this time, the steel drill pin will top the inner hole of the steel drill pin......
