Rigging Equipment

Rigging SafetyIndustry Fundamentals and Occupational Safety Unit 6

Basic SafetyFollow the recommended procedure Know all the aspects of your job:Tools/EquipmentTasks that needs to be completed and how to complete tasks accuratelyMake sure those operating the rig are certifiedKnow proper communication

Basic SafetyTake care of the equipment; the better it runs the safer it will be to work withProperly store toolsLook out for others Use the proper communication Inspect equipment before use

Synthetic Sling Inspection Slings must be inspected before each use, visually and physically, for any rejection criteria.Rejection Criteria includes but is not limited to:Missing identification tagCut severing the outer layer exposing the loadbearing yarnA knot that cannot be removedA punctureLoss of flexibility for any reason

Other criteria for rejection includes: heat damage, UV damage,chemical damage, overload damage which resulted from over stretching, or a snag in the sling reveling warming yarn.4Synthetic Sling Inspection

Alloy Steel Chain InspectionAlloy Steel chains must be inspected before use, physically and visually.Rejection Criteria includes but not limited to:Missing identification tagHeat damageExcessive wearAny damage or change in links:StretchingBroken loopTwistingRustChippingBending

Wire Rope Sling Inspection:Wire rope slings must be physically and visually inspected before each use. If there is any damage the sling needs to be immediately removed from use.Rejection Criteria includes but is not limited to:Broken WiresKinkingBird CagingRustHeat Damage

Wire Rope Damage:

Shackle Inspection:Shackles must be inspected before each use; if any damage is found the shackle should not be used for the lift.Rejection Criteria includes but is not limited to:Cracks or damage to the body of the shackleWrong pin for the shackleBroken, loose or bent pinMissing correct markings (capacity and size)

Shackle Damage:

Eyebolt Inspection:Eyebolts must be visually inspected before each use and inspected by a qualified rigging inspector at least once a year.Rejection criteria includes but is not limited to:Scraping or abrasionStress cracksRust BentAny deformation

Lifting Clamp Inspection:Lifting clamps need to be inspected before each use to check for any damage that can affect the safety of the load.Rejection Criteria Includes but is not limited to:CracksGeneral wear and tearLoose screwsRust

Rigging Hook Inspection:Rigging hooks should be inspected, along with the rest of the sling, before each use for damage that makes the hook no longer safe to use.Rejection Criteria includes but is not limited to:5% increase of hook length 10% degree change from the unbent plane of hook15% increase in opening of hookCuts or gougesRust

Hoist Safety/Sling StressHoist Safety:Keep chains and ropes clean Always perform lifts with supervisionAlways use appropriate protective gearSling Stress:As the angle of the sling decreases the stress on the sling increases*90 degrees (straight up and down) will have the least amount of stress

Risk ManagementRisk management is when the area that the lift is occurring is analyzed before the lift begins. Risk management planning can reduce the danger of the work siteTips:Check locations of any structure in the work area to make sure it wont obstruct the lift while the rig is movingCheck for pedestrian traffic; rope or tape off the area for safetyCheck the weather, especially for wind and fog

Load SafetyKeep the swing path of both front and back of the rig clear.Do NOT manhandle the load into position.Never stand under load being hoisted.Never attempt to slow load that is spinning too much; let it slow naturally before attempting to place it on the ground.If you are signaling make sure the rigger can see you at all times; if you are the rigger do not move the load until you can see the signaler.
