Rigging Review
All rigging must meet 1926.25.
All rigging must be rated and engineered for lifting.
All rigging must have a Working Load Limit(WLL).
Rigging “slings” are rated and engineered.
All rigging must be tagged or marked with a capacity.
Most rigging has a 5:1 Safety Factor.
Chain Slings have a 4:1 Safety Factor.
Chain slings can be used for rigging.
Non-rated chains cannot be used for rigging.
30* Angle = Dead Man’s Angle.
60* Angle = Rigger’s Angle.
Acceptable steel grades are 8,10, 80 and 100.
Only forged steel can be used for rigging.
Malleable steel cannot be used for rigging.
As sling angle drops, stress increases and capacity decreases.
Shackle up one diameter size for wire rope slings.
Do not rig over sharp edges.
90-degree basket capacity is twice vertical capacity.
Choker capacity is 75% of vertical.
WLL for 2 legs at a 30-degree sling angle equals single leg vertical WLL.
Only trained competent riggers are allowed to rig loads.
Rig over the Center of Gravity (COG).
4 Rigging Rules:
- Know your weight
- Know your capacity
- Control the load
- Retain the load
