A cable grip is a woven sleeve with an eye, that slides onto a cable to become an attachment point.
Due to the helical design of the weave, the grip will shrink onto the cable much like a Chinese Finger Trap, and will only tighten the more you try to pull it off.
A hose restraint prevents a pressurised hose from whipping, in the case of unexpected disconnection at the coupling.

What is the difference between tubular and lace-up?
Comments Off on What is the difference between tubular and lace-up?
Tubular grips can be slid over the end of the cable, if the end of the cable is not accessible then a lace-up grip can be wrapped around the cable at any point.
Lace-ups are available in offset or double eye only.
This is the most typical type of hauling grip, the cable can be pushed right up into the end of the weave, but cannot pass through it. It gives you an attachment point at the end of the cable, and right in the centre.
An offset eye grip is typically used for load restraint, or load sharing, and allows the cable to pass through the grip so that the grip can be positioned anywhere on the cable.
A double eye grip has two eyes, one eye directly opposite the other.
These grips are used for many purposes, but mainly when the installer wishes to pull the cable to a fixed position with one eye, and then attach it to that position with the other eye before disconnecting the winch.
Galvanised wire has a higher tensile strength, but a lower corrosion resistance than stainless steel.
Stainless steel is recommended for corrosive and marine environments.

Aluminium alloy, copper, or stainless ferrules?
Comments Off on Aluminium alloy, copper, or stainless ferrules?
For many above-ground applications aluminium alloy ferrules will suffice.
Copper or stainless is available as an alternative where aluminium alloys are not permitted due to spark hazards or corrosion.
Aluminium alloy ferrules are only available for use with glavanised wire, and will not be combined with stainless steel wire.
Soft eyes are preferable for general hauling, and will collapse to fit through conduits and rollers. A thimble will protect the eye from wear and tear, but will also not allow the eye to collapse.
Thimbles should be used in permanent or semi-permanent load restraint or load sharing applications where some load will be applied to the grip for extended periods of time, or where the eye will potentially rub against another hard surface.
It is important to note that a cable grip should never be used as a permanent termination, nor should a hauling grip be left attached and at load for extended periods of time during a haul.

What is the safety factor for cable grips?
Comments Off on What is the safety factor for cable grips?
Our Working Load Limits are based on a safety factor of 3:1, as a general guide only. There is currently no Australian Standard for cable hauling stockings and each application should be judged on its own merits, by experienced operators.
