In all lifting equipment, the single girder crane application is particularly important, machinery and equipment lifting handling, in normal operation, have standardized on related operations execution system, pay attention to the following specific actions: 1 When lifting weights first class (or the maximum load weight), should be suspended height of 0.5 meters from the ground after the weight is lowered again, check the brake performance, reliable after confirmation commercial river lifting equipment , then normal operation. 2, the command signal is unknown or not hanging chaos command; no more than nominal weight hanging; lifting machinery maintenance staff or the operator does not comply with the rules of squeezing the accident occurred is squeezed between the cage and the frame body caused by; overturn job bruised accident. Engaged in lifting, flipping, down a job, professional equipment lifting, hoisting method due unreasonable, chucking strong, spreader inappropriate choice of command and the operator station is bad, resulting in the suspension load instability, the impact of the suspension load swing Flip operations caused by hit, hit, hit, squeeze, pressure and other casualties. Lifting Jishang accident occurred in Lifting operation is the most common casualties, which is very dangerous, serious consequences.
