Wire Rope Grips User Guide
What are wire rope grips used for?
Wire rope grips are a fitting that can be used to create an eye or loop termination at the end of a wire rope. The only tools required are something to tighten the nuts, some heavy-duty tape to stop the rope unravelling and the knowledge to fit them correctly. They are available in a range of types including Australian standard, commercial, US standard and stainless steel.
Correctly fitting a wire rope grip
To achieve maximum efficiency, you need to ensure that the correct type of wire rope grip is selected and fitted correctly. Many wire rope grips are not suitable for lifting applications. Measure the rope diameter and use a wire rope grip of the same size as the rope. If the wire is plastic coated remove the coating, measure and fit only to the metal part of wire rope. The u bolt of the grip must be fitted on the dead side and the saddle on the side of the live line. The correct placement and tightening of the grips on the rope are essential. A minimum of 3 grips should be used for all eye terminations. If not tightened enough the wire rope can slip through the grips and cause the equipment to slip. If overtightened it could cause damage to the wire rope and early failure.
What do I need to check?
Ensure that all markings are clear and that there are no cracks, rust, nicks, cuts pitting etc. Check that the nuts are tightened correctly and that the grip is fitted correctly to the rope. You should never repair a wire rope grip by welding, heating or bending as this may affect the performance. A wire rope termination made with wire rope grips must be inspected regularly and before every use.
How not to use wire rope grips
Wire rope grips should not be used for making terminations on live running ropes. Live running rope are ones that apply force to a moving object or where the rope is required to support persons or dangerous or substantial loads. Wire rope grips should not be used where there is a possibility of the rope having to be lengthened at that end.
The grips in a connection
The efficiency of a wire rope assembly with wire rope grips depends on the number per connection, correct placement, and the care and skill in the fitting and tightening of the grips. Please obtain expert advice on the number of wire rope grips per connection. The grips in a connection should be spaced evenly along the wire rope at distances between adjacent grips of approximately six times the rope diameter.
