Wedge Socket
A wedge socket is a critical rigging component designed to create secure, reusable terminations for wire ropes in lifting, hoisting, and anchoring systems. Engineered for extreme loads and harsh environments, it consists of a tapered socket body and a wedge that mechanically grips the wire rope without splicing, ensuring maximum strength retention.
Overview
Standard: GB/T 5973-2006
Purpose: fix and connect wire ropes.
Manufactured method: casting or integral forging.
Components: the socket body, wedge, and cross pin.
