Checking the Wire Rope for all Winches


Bump Test on a Gas Detector

Firstly ensure that this is always done wearing gloves as any protruding wire will cause painful cuts. Always start at the connection hook and ensure that locking mechanism operates freely and is free from corrosion or any distortion. If the hook has an activation indicator make sure that this is intact. If the indicator is showing that a fall has taken place, usually a red ring is exposed, withdraw the unit from service immediately.

Once the connector has been checked pay out all of the wire rope until it reaches the stop limit. This can be a plastic shroud, paint, pin or tied back wraps. The manufacturer’s instructions should be referred to for your exact model.

You should be examining the wire rope for rust, cracks, burrs, bird nesting and general signs of wear that will make it unsuitable for use. If the wire has what is called a pig tail or a spiral section this is because it has been used for lifting goods. The weight of the goods stretch the wire strands and produce this pig tail effect. If this is visible again the winch should be withdrawn from service. A rope in good condition should feel fairly supple and flow easily.

Once all of the rope has been checked rewind all of it back onto the drum in the correct direction ensuring that you apply tension by passing it through your gloved hand to stop the lays being formed loosely. If this is always done prior to use, not only will you have a safe winch to use but you will also have one that will cost very little when it is serviced.
