How to detect the tilt of a truck crane and methods for correction

Thread Content

When operating the machine, the truck crane driver notices that the frame tilts significantly before the two front vertical cylinders have touched the ground, and that the upper part of the right leg tilts more than the left front leg. At this point, operations must be stopped immediately, and the frame and leg structures of the entire machine need to be inspected one by one. 1: Check the cross-sectional areas of the leg extensions at the front and back, as well as at each edge interface, to ensure they remain level and stable. In addition, it is also necessary to check whether the surface of the box inside the truck crane is deformed. II: Additionally, we can remove the telescopic joints of the front and rear legs as well as the vertical cylinder together. Then, place it on a smooth horizontal surface to check for consistency. III: If it is found that the upward arching degree of the truck crane’s frame is less than 5 millimeters, however, the front part of the frame also shows localized upward arching deformation. Considering the above circumstances, we must repair the vertical cylinder. Generally, we can use flame heating to correct local camber deformation, or we can use an oxy-acetylene flame method for prefabrication.
