The single girder crane has two operation modes: ground and air. There are two kinds of ground operation: handle operation with cable and handle operation with remote controller; Air operation refers to the operation in the cab. There are two types of cab: open type and closed type, which can be divided into left or right installation according to the actual situation. There are two types of entrance direction: side and end to meet the user's different needs.
Reasons for single beam crane to start and stop swaying:
1. The transmission parts have wear clearance. If the gear of the gear coupling and the gear of the reducer and their combination keys are loose, the clearance between the connecting bolts and the holes of the transmission shaft will be increased.
2. The wheel joint key is loose.
3. One of the wheels doesn't work. The bearing is not clamped flexibly due to the misalignment of the base plate fixing the wheel bearing seat, so the wheel stops first when parking.
4. The brake torques of the brakes on both sides of the separately driven cranes are inconsistent, and one brake wheel has stopped while the other continues to rotate.
As the vehicle body twists and shakes, the wheels on both sides rotate accordingly, so that the transmission components of the vehicle body are repeatedly impacted for many times, accelerating the wear of the combined parts such as gears and keys (a basic type of component failure). Serious twisting and shaking may also cause the transmission shaft (consisting of shaft tube, expansion sleeve and universal joint) to break.
The bridge is deformed. At the same time, one side of the bridge leads and the other side lags behind, while at the moment of springback, the leading side lags behind and the lagging side leads. In this way, the bridge vibrates back and forth, causing plastic deformation or cracking at the connection between the bridge and the beam.
