Gantry Crane Main Girders Camber

Apr 11, 2017
The gantry crane main beam is a flexible structure, under the action of the load, the main beam will appear the torsion deformation. When the load is removed, the deformation will disappear, the main beam return to the original state. 
 
In order to prevent the lifting electric hoist (electric trolley) from climbing phenomenon, increasing the running resistance, causing the body vibration, compensate and eliminate the torsion deformation, when the gantry crane bridge beam span is greater than 13.5m, the main beam will preform into the arch, the main beam surface to the horizontal point on the arch curve distance is called the camber, recorded as f0, the gantry crane main beam camber standard value is 1/1000 of the span.
