According to the Safety Guidelines for hoisting equipment Operation, the earth should be leveled up before the crane is put into use and the machine body should be set stable, the working area should has enough space. If the crane needs to walk across the soft earth during travelling process, choosing another route is the best choice. In order to avoid earth collapse, the machine should not stay in the soft earth for too long time.

The operator should check the ground conditions before the crawler crane starts working. The ground should be hard and smooth enough to bear the machine. Plank or hard soil block should be padded beneath the machine’s legs if the earth is too soft to bear the crane. Confirm the weight and gravity center of the lifting object to avoid overload.
