Crane, Hoists and Rigging

Crane, Hoists and Rigging

When incidents occur involving cranes and hoists, the results can be devastating because:

  • Death or serious personal injuries often result from dropped loads
  • The high value of the load on the crane or hoist
  • The heavy weight of the load on the crane or hoist
  • The value of property or equipment damaged by falling loads may be high
  • Excessive costs of work stoppage
  • Damage to reputation

Crane and hoist incidents are generally the result of either improper operation or equipment failure. Examples are:

A.    Improper operations

  • Unknown weight of load
  • Failure to consider bearing strength of support surfaces
  • Failure to understand load charts or load-moment indicators
  • Improper rigging
  • Improper equipment selection
  • Failure to survey/control the site
  • Failure to properly maintain equipment
  • Operator errors

B.    Equipment failure

  • Wire rope failures
  • Rigging failures
  • Component structural failure
