Overhead Crane Inspection

Overhead Crane Pre-shift inspections do not have to be lengthy. You are basically looking for obvious things that might be wrong with the crane.

Overhead Crane Monthly or yearly inspections, of course, should be the thorough and performed by a competent individual.

Overhead Crane Inspection includes:

1. Loose Fasteners Inspection

  • Check all fasteners for loose, stretched, missing, or broken fasteners.
  • A good clue is checking for cracked paint around the fastener that shows there has been movement.
  • Sometimes a build up of dirt or grease can do the same thing.
  • Using a torque wrench to check for tightness does not always work. Corrosion could give you a false reading.
  • Replace a loose or stretched bolt rather than tighten it. It probably has been damaged.
  • Be sure to replace the bolt with a grade 8 or beter.
  • If there are bolts near by that show signs of looseness, then replace them all.

2. Cracked Welds Inspection

  • Check cracks in the structure and in all welds.
  • A crack in a weld will always start on the end and work itself along the entire weld until it fails completely.
  • Many times a crack in the paint will be a clue to a weld that is failing.
  • If caught early, the crack many times can be ground out and re-weld.
  • Before welding on any part of the crane, make sure you have a certified welder and if it is on a structural part of the crane you should get the manufactures procedure.
  • Also, try to determine why it cracked in the first place. Is the crane being overloaded or used improperly.
