• Annual Inspection and Test Requirements
• General. The intent of this inspection is to ascertain the safety of the
rigging and other critical equipment parts that could result in loss of life or
equipment damage if failure occurs.
• In general, the inspection must include all wire and manmade rope,
fittings, block fittings, hooks, links, shackles and associated pins,
swivels, boom and frame pad eyes, hoist control linkages, brake
springs and linkages.
• Any visible permanent set or deformation in the form of bent pins,
elongated holes, bent or distorted staples and pad eyes are clear
indications of overload or improper rigging. Any permanent set or
deformation must be reported, and the rig should not be used until the
cause is found and corrected. The operator should also be aware of
recurring cracks in paint, particularly in areas of high stress corrosion.
To inspect for surface cracks, remove paint and wire brush clean
surfaces.
• The following requirements are generic in nature, and are included in
inspections as applicable in 29 CFR 1919 - Gear Certification.
• Cradle or securely position the boom, crane, davit, or frame and
remove all wire or manmade rope. Inspect the wire or manmade rope
per 29 CFR 1919.24 - Limitations on the use of wire rope.
• Visually inspect all sheaves, swivels, blocks, block hangers, pad eyes,
connecting links, shackles, hooks, winches and associated pins for
corrosion, wear, deformation, cracks and any other condition that may
lead to failure. Inspection of sheaves includes sheave gage wear
measurement IAW 29 CFR 1919 Subpart E - Certification of Vessels:
Tests and Proof Loads.
• Do not disassemble blocks, topping lift, vang swivels or equivalent
devices unless there is reason to suspect damage, wear, corrosion, or
marginal condition when last overhauled. Inspect hoist and rotating
gear brake springs and linkage, where appropriate. Carefully check
brake springs for permanent set and compression, and replace if
necessary.
NOTE: (As applicable) Failure of brake springs in service can result
in loss of control or release of load. Inspect hydraulic or pneumatic
hoses for ballooning, cracking and corrosion. Inspect electrical wiring
and connections for corrosion. Inspect brake solenoids and switches
for corrosion and contact wear.
• Inspect and lubricate all moving parts and wire rope per the
manufacturer technical manual or Preventive Maintenance System.
• Replenish the gear lube in the self-contained reservoir gearboxes if
they have less than five gallons of lube oil. If possible, drains will be
opened and the boxes checked for condensation at the bottom of the
tanks. Check any magnetic plugs, if equipped, for particles. Draw oil
samples of gearboxes with capacities in excess of five gallons for
analysis as per good engineering practice.
