The operating track of the bridge-type grab ship unloader driver's cab is made of I-beam,and the track is prone to deformation after long-term operation.There are defects in the connection hanging point of the driver's cab,and the equipment has insufficient wind resistance,which may cause the driver's cab to fall when there is a sudden strong wind.Aiming at this problem,on the basis of evaluating the safety performance of the bridge-type grab ship unloader driver's cab,a safety performance scheme of the bridge-type grab ship unloader driver's cab of is given,and its structure is improved,and a new brake protection device is designed and installed.The application effect shows that the implementation of this scheme can improve the safety performance of the equipment.
