Lifting illegal operation and improvement program

One, close to the limit does not slow down
     Universal  gantry crane  span relatively large, the use of driver control, prone to car line at the end of the beam away from the driver's cab, the driver is difficult to determine the exact location of the car, causing the car near the end of the beam does not slow down, hit the buffers at the end beam stopper, damage to the formation of the track, resulting in loosening the track.
     Adjustment method: Use the units should strengthen the system construction, strengthen the common gantry crane operator safety education and skills training.
Second, lifting objects, partial on one side
       Lifting heavy loads, partial on one side, the side of the track will be under pressure, long-term this operation will be this side of the track and the load-bearing beams causing serious injury, can cause serious side trajectory of the whole or part of the sinking . This situation allows universal gantry cranes lateral movement occurred during operation, causing the plate and rail loose. (Like two people bickering children, near the weight of people affected by a larger force)
        Adjustment method: strengthen the system construction, strengthen the management of  hoist crane  and enhance the operator's training and management. If one side of the track has already appeared in whole or part sink, should be promptly elevate this side of the track.
       Recommendation: direct cause of many accidents because of improper operation of the operator, so the use of units should strengthen the system construction, strengthen the common gantry crane use management, as well as to strengthen the skill of the operator training and safety education. Only the use of units and operations staff pay attention to it, in order to fundamentally reduce the failure rate and the accident rate.
