Single girder crane is a common handling equipment, it is operated in two ways, respectively, ground and air. Ground operation has two types of operation with wire handle operation and remote control handle operation; air operation refers to the driver's room operation. The driver's room has two types of open and closed, which can be divided into two forms of left or right side installation according to the actual situation, and two types of side and end entry directions to meet the user's choice in a variety of different needs. However, sometimes there will be shaking when working, for the above phenomenon, the company has compiled some factors, you can look at.

However, sometimes there will be shaking when working, for the above phenomenon, the company has compiled some factors, you can look at.
1, the transmission parts produce wear gap. Such as the gear of the gear coupling and the gear of the reducer and its bonding key is loose, and the gap between the connecting bolt of the transmission shaft and the hole is worn large.
2、The wheel bonding key is loose.
3, a wheel rotation does not work. Due to the fixed wheel bearing seat pad is not correct so that the bearing clamping is not flexible, the wheel stops first when parking.
4, separately driven crane brake torque on both sides of the brake is inconsistent, stopping a brake wheel has stopped, the other is still continuing to rotate.
5, due to the car body twisting shaking, both sides of the wheel with the corresponding rotation, so that the transmission parts of the car body by repeated impact, accelerating the gears and keys and other combined parts of the wear (a basic type of parts failure). Severe twisting and shaking and drive shaft (drive shaft composition: axle tube, telescopic sleeve and universal joint) the risk of twisting off.
6、Make the bridge deformation. As the bridge at the same time one side ahead, one side lagging, and in a moment of rebound, ahead of the side but lagging, lagging side that is ahead of. This oscillates before and after the twisting and shaking, so that the bridge and the beam connection produces plastic deformation or cracking.
