Safety Risk Analysis And Control Of Manual Chain Hoist 2

- Jan 18, 2019-

      Risk source point: The strength of the temporary hand chain hoist suspension hanging point is insufficient.


      Risk analysis: At the stress concentration point during lifting, the maximum torque or weak point breaks and the heavy object falls.


      Risk prevention: Try to avoid welding temporary suspension points. It is really necessary to use continuous welds, reasonable welded structures and materials large enough.


      Similar risks: 

1. Temporary suspension hanging spot welding on the pipe wall or directly welded to the container wall; 2. The hook of the manual chain hoist is hung on the hanging lifting point, and the hook is easily pulled out from the hanging point.
