There are mainly the following types of copper bushing for cranes:
Guide pulley copper bushing: installed in the crane guide pulley, play a role in reducing the friction between the pulley and the shaft, reduce wear and tear, to ensure that the pulley can rotate smoothly, so that the crane’s lifting and running mechanism can work normally. For example, XCMG and other brands of crane parts have this guide pulley copper bushings.
Big arm bushing copper bushing: used to connect the crane arm and other parts, play a role in supporting and reducing friction. Big arm in the working process will continue to retract, rotate and other actions, big arm bushing copper bushing can ensure the smooth progress of these actions, while reducing the wear and tear between the arm and other parts.、

Joint bearing copper bushing: In some joint parts of the crane, such as the connection parts of the crane arm and the turntable, the fixed parts of the wire rope, etc., will use the joint bearing copper bushing. This kind of copper sleeve can withstand greater pressure and impact, and at the same time to ensure that the joint parts of the flexible rotation.
Collector sleeve: In the crane electrical system, the collector is used to collect the current device. Collector copper sleeve installed in the collector shaft, play the role of conductive and reduce friction, to ensure that the collector can collect current stably.
Reel copper bushing: the crane reel will rotate continuously when putting and taking away the wire rope, the reel copper sleeve is installed at both ends of the reel, which plays the role of supporting the reel and reducing friction to prolong the service life of the reel.
