What type of socket uses molten zinc or resin to secure a wire rope?

A spelter socket is designed to secure a wire rope using molten zinc or resin, which is poured into the socket around the wire strands after they have been inserted. This process creates a strong bond, ensuring that the strands are effectively held in place, which is critical for maintaining the integrity of the cable during lifting operations.

The use of molten zinc or resin is essential because it allows the material to fill any voids around the wire rope strands, creating a solid and reliable connection that can withstand significant loads without slipping. This makes spelter sockets particularly advantageous in applications where high strength and safety are paramount.

Other types of sockets, such as molded sockets, utilize different methods for securing the wire rope, such as using plastic or composite materials that are molded around the rope during the manufacturing process. Swaging sockets, on the other hand, involve mechanically deforming the socket to create a crimped connection, which is also different from the chemical bonding used in spelter sockets. Standard sockets generally do not utilize any of these special securing methods and may not provide the same level of reliability as spelter sockets for heavy-duty applications.
