Part 21 Rigging

Section 294 Inspection

The rigging assembly must be thoroughly inspected before each period of continuous use during the shift. Refer to ASME Standard B30.9-2006 for detailed information regarding initial, frequent and periodic inspections. This inspection should be done by a competent worker and should include, but not be limited to:

(a) inspection of wire rope for wear, elongation, damage, i.e. bird caging, kinks, core protrusion, cuts, etc., signs of overloading, corrosion and pitting;
(b) inspection of slings for abrasion, cuts/tears, melting or burn marks, bleaching/corrosion, increased stiffness of material;
(c) inspection of sheaves and hooks for deformation, cracks, wear;
(d) inspection of shackles for crown (bow) wear, cracks, chips, gouges, deformation, and pin wear, deformation, thread damage;
(e) inspection of eye bolts and lift rings for gouges, cracks, wear, deformation; and
(f) inspection of spreader bars, lift beams, equalizer beams, beam clamps, beam trolleys, plate clamps for wear, excessive movement, cracks, broken/worn teeth, loose components, deformation, integrity of connection points.

The criteria for rejection are more fully described in sections 305 through 309. If no criteria are mentioned, reference should be made to manufacturer’s specifications or the specifications of a professional engineer. Rejection criteria for slings are also described in ASME Standard B30.9-2006, Safety Standard for Cableways, Cranes, Derricks, Hoists, Jacks and Slings.
