Basic Hoisting and Rigging Guidelines

The following basic guidelines must be followed for all types of rigging:
  • It is essential to determine the proper style, size, length, diameter and thickness of sling needed for the application prior to use. Select the sling best suited for the job.
  • Never tie knots in slings.
  • Rigging equipment must not be loaded in excess of its safe working load.
  • Hooks must be provided with safety latches.
  • Know the limitations of the lifting device
  • Determine the center of gravity of the load.
  • Protect sling from sharp surfaces.
  • Protect load from rigging, if necessary.
  • Allow for increased tension caused by sling angles.
  • Equalize load on multiple leg slings.
  • Maintain load control. If required, attach tag lines prior to lift.
  • Keep personnel clear of lift area.
  • Lift load a few inches and check rigging.
  • Start and stop the lift slowly.
  • Watch for obstructions and power lines. Maintain at least 10 feet from energized power lines at all times.
  • Use proper hand signals when communicating with crane operators.
