Lug Description
Diagram showing lifting lug composition

Lug comprises the body, retaining head and collar, all manufactured from high strength alloy steel forgings. The retaining head and collar have the same profile as corner box aperture. Retaining head is fixed to the body whilst the collar, in tandem with the retaining head, rotates through a limited arc angle allowing for insertion and retention of the Lug in the corner box. The body contains a lug (shackle bush) for attaching it to a sling or strop via a screw-pin shackle or chain connector.

Basic Lug Geometry

Lifting lug geometry
Body designed as a forging and manufactured from alloy steel, heat treated to give maximum strength and resistance to abraision. The lug bush hole can be machined to suit any appropriate connectors. Current production bush hole diameters are 32mm and 38mm for 8.5Ton and 12Ton respectively.

Prior to general release, a test to destruction was conducted on one of these lugs, and terminated at 64.6 Tons for safety reasons. The lug sustained deformation but without failure of any component parts.

Set of 4 (two of each hand) Rated at 8.5t WLL or 12t WLL per lug.

These Lugs were designed to suit 16mm and 20mm chains having SWL's of 8.5t and 12t respectively. For manual use it is important to keep the combined weight of lug plus shackle, or connector, to a minimum. The two lugs normally supplied are the STANDARD and UNIVERSAL types.

Product Range

Standard and Universal Lugs with typical chain end connectors

Chain end connectors other than those shown here are available but must have the same WLL as the lugs, chain or cable used for lifting slings.
The Universal 12t WLL lug can be connected to US Fed. Spec.12t WLL shackle (not shown here) but the combined weight, together with chain, is considerable and should only be used in exeptional circumstances.
