There are three factors mainly cause the crane derailment. First is the linear velocities of driving-wheel are different. Second, brakes of two sides are not synchronous. Third, the surface hardness difference of driving-wheel is too big.
The solutions are as following. First, for small and mini gantry crane, if the driven wheel is off rail, use jack or other lifting tool and find cart’s driving-motor to flat. Second, if the driving wheel is off rail, adjudge which driving device cause the problem. If the big driving device causes the problem, it is necessary to invite professional maintenance person to detect on-site. If the small device causes the problem, just make crane work first, then make testing operation according to jacking height, and exclude the obstacles.
