Air winches checklist:
• Check the condition of the brake lining (no oil contamination is allowed on the lining).
• Ensure that the brake linkage system and brake adjustment are correct. Who is qualified to adjust and maintain the winch?
• Make sure that a ball valve is used in the air supply line and that the handle is within easy reach of the winch operator.
• Ensure that the free-fall handles on utility hoist winches have been disabled or removed.
• Check for oil and air leaks.
• Check the condition of the wire-end termination.
• Check that the winch control handle returns to neutral when released.
• Ensure permanent safe working load (SWL) signs are clearly displayed.
• Ensure a protective drum cage is fitted.
• Make certain a spooling device is fitted.
• Confirm the controls correctly indicate UP and DOWN functions: check whether the winch controls are operating the same on all winches.
• Check the condition of the winch foundation and foundation bolts, as well as recent NDT inspection records.
• Verify that an air exhaust noise suppressor is installed.
• Check the condition of the snatch-blocks and review their inspection reports.
• Ensure the snatch-block sheave diameter is at least eighteen times the diameter of the wire in use.
• Check the condition of the wire (API RP 9B).
• Confirm that the non-gear-driven man-riding winches are fitted with an automatic and a manual brake.
• Confirm that the man-riding winches have non-rotating wire installed.
• Ensure that no rubber hoses are fitted in the man-riding winch air supply lines.
• Check that the maximum pull/speed adjustment on the man-riding winches is correct.
• Ensure that dedicated man-riding winches are installed in their area of operation.
• Confirm that there is an accumulator system for the man-riding winches, if applicable.
