Rigging equipment shall be inspected prior to use on each shift and as needed during its use to ensure it is safe. Defective or suspicious equipment must be removed from service immediately.
Makeshift rigging equipment is prohibited.
Use of wire rope:
Safe working loads for wire rope rigging equipment, as provided by the manufacturer or as determined by approved informational charts (i.e., OSHA 1926.251 Tables H-3 through H-14), shall not be exceeded when handling material, etc.
Wire rope used in lifting, lowering or pulling loads shall be one continuous piece without splice.
Eye splices in lifting bridles and slings shall not be made with wire rope clips or knots.
When using wire rope clips or similar items to form eyes and splices in cables, the manufacturer’s instruction must be strictly followed with respect to size, number, and installation procedure of the particular clips or similar items.
Wire rope rigging equipment shall be taken out of service when in any length of 8 times the diameter, the total number of visible broken wires exceeds 10% of the total wire construction of the wire rope (i.e., a 6 × 7 constructed 1” diameter cable has 42 wires. 10% of 42 = 4 wires. 1” diameter x 8 = 8 ins.; thus, if the cable has more than 4 visible wires broken in any 8 in. section it must be replaced).
All shackles and hooks used in rigging shall exceed the manufacturer’s safe working load rate for the load being handled. Unidentified shackles must conform to an approved safe workload informational chart (i.e., OSHA 1926.251 Table H-19). Unidentified hooks must be treated and documented at (2) times the intended load before using.
