Lifting loops

Lifting loops and sockets are interrelated lifting components which are used in the pre-cast concrete structure manufacturing and building industries to aid transportation and placement of structural components conveniently and safely.

Designed for long life, Slingco lifting loops are manufactured from wire rope clinched firmly into an externally threaded (standard ISO/DIN metric or metric round form thread) steel ferrule which mates on application with a permanently inserted steel socket ofthe same same thread form and size.

The recommended safe working load (SWL) is normally based on a 5 to 1 factor of safety of the wire rope minimum break loading, as per BS1290:1983. By arrangement, a 6 to 1 factor of safety can be offered on metric round form (Rd) type loops.

Proof loading to 2 x (SWL) for the application is the normal practice. A test certificate is issued which can be easily referenced by an attached identification tag.

Lifting sockets

These strong steel tubular sockets are supplied with a through hole below the thread to take a reinforcing bar, located and tied to the main reinforcement in order to provide a secure anchorage point in the concrete. Available in zinc plated steel or stainless steel, each socket is provided with two plastic plug inserts for protection against ingress of concrete or damage to threads.

Note: Lifting loop and socket must be carefully matched to correct thread form and size. (M) Metric ISO threads are not compatible on thread form with (Rd) metric round form threads.

Plastic plugs can be obtained separately.
