Analysis of gantry crane torsion

Dec 16, 2019
After a period of work, the gantry crane may sway when starting and stopping, causing the following effects on the equipment:
 
1. Deform the bridge.
The gantry crane frame advances on one side and lags on the other side. At the moment of rebound, the leading side lags behind, and the lagging side leads. This oscillates back and forth, causing plastic deformation or cracking at the connection between the bridge and the beam.
 
2. Transmission parts are worn.
Due to the crane body swaying, the wheels on both sides will rotate accordingly, so that the transmission parts of the crane body are subjected to repeated repeated impacts, which accelerates the wear of gears and keys and other combined parts. Severe twisting also risks breaking the drive shaft.
