The reason of gantry crane sway

Dec 26, 2019
1. The transmission parts generate abrasion clearance.
2. The wheel coupling keys are loose.
3. A wheel fails to rotate, the pad of the fixed wheel bearing seat is not correct, the bearing is not clamped flexibly.
4. The braking torques of the brakes on the two sides of the gantry crane that are driven separately are not the same. One brake wheel has stopped while the other is still rotating.
5. If the gantry cranes are driven separately, the parameters of the two motors are not matched, resulting in unsynchronization.
6. The difference between the two brakes is too tight.
