Expanding Socket Rock Anchor 0.75″ (19.1 mm) Diameter Rod, 15″ (381 mm) long with Triple eye.
This Rock Anchor expands and socket design wedges against solid walls of rock.
An expanding rock anchor is an elongated engineering tool, usually made of a sturdy metal such as steel. They are used to transfer tension from the outside to the inside of a solid material such as rock or concrete. The purpose of this is to maximise the stability or the safety of the structure (or both).
Its design is a cross between a bolt and a screw. At the top end, it has a handle and an 'eye' to operate the anchor. At the lower end, it has two wedges, designed to expand outwards and pressurise inside the mass.
expanding rock anchors are utilised in a wide variety of industries that work with materials such as rock and concrete. These include infrastructure (e.g. the construction of bridges, tunnels, and highways), telecommunications (e.g. to support or protect cable suspension), and mining and refinery.
