Lifting and Rigging

  • No “free-rigging” is permitted at any time.
  • All employees performing rigging and signaling must be “Qualified” through documented training and authorized by a Supervisor.
  • All rigging equipment and connecting components must be inspected by a Qualified Rigger prior to each use.
  • All rigging equipment must be used within the manufacturer specifications without exceeding capacity or load limits.
  • All rigging components must be labeled or stamped with the rated capacity clearly visible.
  • Never use any damaged rigging equipment. Promptly remove from service any defective equipment – Destroy or discard.
  • Never stand or travel beneath a suspended load. Operators must never swing a suspended load over people.

Standard Lifts

A Standard Lift Plan (SLP) is required for every lift or series of lifts (if repetitive routine lifts are being performed). At a minimum, the following items must be addressed:

  • Roles, responsibilities and qualifications of all personnel involved in the lift including the Lift Supervisor, Qualified Operator, Qualified Rigger and Qualified Signalperson.
  • Area assessment and preparation including ground stability, overhead powerlines, path of travel, any obstructions, suitability of the load’s destination, blocking/cribbing requirements, etc.
  • Crane or other load handling equipment (LHE) considerations including capacity, configuration, limitations, valid inspection, etc.
  • Load parameters including weight, center of gravity, radii, and configuration/dimensions.
  • Rigging requirements including type, load limits, pre-use inspection and need for softeners.
  • Environmental considerations including visibility, wind speed, lightning in the area and storm forecasting.
  • Safety zone and traffic control requirements around the lift area.

Critical Lifts

Critical lifts require a more comprehensive plan. Any vertical lift is classified as “Critical” if any of the following conditions are present:

  • The use of more than one crane, or more than one piece of load handling equipment (LHE), is required to lift, stabilize or support the load during movement, assembly or installation of the load.
  • The maximum anticipated load is at or above 75% of the rated capacity according to the lifting equipment’s load chart.
  • Personnel are being lifted.
  • Lifting submerged loads.
  • The load item is unique and, if damaged, would be irreplaceable or irreparable.
  • The load item, if damaged or upset, would result in a release of a hazardous material into the environment.
