1. Do not make lifts beyond rated load capacity of the crane scale, sling chains, rope slings, etc. 2. Do not operate the crane scale if ropes, slings, cables, chains, etc. show any sign of defects or excessive wear. 3.

• Magnetic Particle or Dye Penetrant crack detection of all components of the load train assembly should be conducted annually. If the crane scale hook, shackle or lifting eye are painted, visual inspection should take this coating into consideration. Surface variations can disclose evidence of heavy or severe use that requires more detailed analysis. -
