Lifting operations several cases of people squeezed collision

  Collision is a person who extrusion operations personnel in the operation of the  gantry crane  squeeze collisions. In lifting operations are common casualties, which is very dangerous, very serious consequences, often will result in death. Lifting operations extrusion collision people mainly in the following situations:
   (1) gantry crane hanging objects run in the process of swinging squeeze collision people. Main reason is: First, as the driver to improper operation, excessive speed change operation mechanism, so that hanging objects have a greater inertia. Second, because the command is incorrect, lifting route unreasonable, resulting in hanging objects swing violently collide squeeze people.
   (2) hanging objects placed instability occurs dumping smashing hit people. Reasons: First, because of improper placement of hanging objects, hanging objects to prevent instability on major did not take the necessary safety precautions. Second is due to lifting operations at the scene of mismanagement.
   (3) in command or overhaul mobile crane operations are squeezed collisions, that is, as people in the door mechanism and slewing crane operation between institutions, subject to the operation of the lifting machinery extrusion collisions. The reason is: First, because the command station operating personnel improperly; second is due to maintenance operations did not take the necessary safety precautions.
   (4) In the roving inspection or maintenance hoist gantry crane  operations are squeezed collisions, ie workers and between buildings in lifting machinery, lifting machinery run by extrusion collisions. Main reasons: First, because of inspection staff or maintenance personnel and drivers lack of correlation; second is due to maintenance operations did not take the necessary safety precautions.
