To use a wedge socket, the wire rope is threaded into the tapered opening of the cable wedge socket and then coiled around the wedge. The wedge slots into the socket and the load is gently lifted, ensuring that it isn’t jolted. The weight of the load causes the wedge socket to tighten. The more you haul, the more the wedge tightens in the socket. The wedge and socket acts as a vice in securely gripping the rope.
Wedge sockets secure the rope to the end attachment by passing it around a grooved, wedge-shaped piece of steel and pulling it down under load into the bowl of the fixture.
Wedge sockets are popular because they can be installed in field and adjusted in field – providing 80% efficiency of rope breaking strength. Wedge sockets are popular in applications where the wire rope may be subjected to abuse and abrasion—particularly in construction and mining applications.
Wedge sockets allow the end-user to adjust the length of a wire rope cable if exact and matched sets of crane cables are not available.

Safe Use of the Cable Wedge Socket
As with all lifting equipment, safe use is essential:
- Your pin, socket and wedge should be inspected before and after each application to ensure that there are no cracks or deformities.
- Ensure that the rope end is properly welded and not frayed before inserting it into the wedge socket.
- The steel rope should be in line with the centre of the pin.
- Before putting the equipment into use, ensure that the wedge is firmly in place, using a hammer.
