Why does the double-beam crane twist?

(1) The transmission parts produce abrasion gap. For example, the gear of the gear coupling and the gear of the reducer and its coupling key are loose, and the gap between the connecting bolt and the hole of the drive shaft is worn out.

(2) The double overhead crane wheel coupling key is loose.

(3) A certain wheel does not turn well. Because the backing plate of the fixed wheel bearing seat is not correct, the bearing is not flexibly clamped, and the wheel stops first when parking.

(4) The braking torques of the brakes on both sides of the crane that are driven separately are inconsistent. When parking, one brake wheel has stopped and the other is still rotating.

(5) For cranes driven separately, the parameters of the two motors are not matched, resulting in asynchrony.

(6) The tightness of the two brakes is too different.

Solving the above-mentioned factors of crane wiggling will completely eliminate the occurrence of crane wiggling.
