Types of DAWSON Wire Rope Sockets:
Swage Sockets
A swage socket is applied to the end of a wire rope cable and is then forced into place using special dies and a hydraulic machine called a swager. When properly applied with the correct sized fitting, swaged sockets have an efficiency rating of 100% of the breaking strength of the rope.
Swaged fittings are more resistant to wire fatigue at the point where the cable and socket come together.
However, swaged sockets are not recommended for use on fiber core or lang lay wire rope cables.
Spelter Sockets
A poured socket, commonly referred to as a spelter socket, attaches a termination fitting onto the end of a wire rope cable by pouring molten zinc or resin into a socket that then hardens and holds the fitting onto the end of the cable.
Poured sockets are one of the most efficient types of wire rope end attachments—delivering 100% efficiency of rope breaking strength.
Due to the rigidity of this type of termination, the wires of the rope are subject to fatigue where the wires enter the socket, if the poured socket is subject to constant vibration.
Wedge Sockets
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.
