What Toco supplies in steel wire rope slings

Toco assembles steel wire rope slings in house and made to order, with quick turnaround and full traceability on every sling. Each sling is built to a specified length and rated working load limit with the construction and end fittings the lift requires, from a simple eye formation through to heavy duty hooks.

Configuration	Typical use
Single leg	Straight, choked or basket lifts on one attachment point
Double leg	Balanced lifting of a single load on two points
Triple and quadruple leg	Load shared across three or four pick up points
Eye and eye	A single length with a formed eye at each end for choke or basket use

Length, configuration and end fittings are built to order. Rated working load limit is confirmed per certificate on enquiry.

What makes up a steel wire rope sling

A wire rope sling is the rope plus the fittings that form and protect its eyes and terminations. Toco selects and fits each component to the rope and the application.

Component	Role
Ferrule	Swaged sleeve that secures the rope to form the eye of the sling.
Thimble	Fitted into the eye to hold its shape and protect the rope from wear, extending service life.
Spelter socket	A poured termination for permanent end fixings, for example power line towers and mining headgear.
End fittings	Eye formations through to heavy duty hooks, fitted to suit the load and attachment point.

Constructions and terminations Toco supplies

Toco assembles slings from the rope construction best suited to the lift. The most common for slings are 6 x 36 fibre core, galvanised or ungalvanised, and 6 x 19 fibre core, galvanised, chosen for the balance of strength, flexibility and fatigue and abrasion resistance the job needs. Eyes are formed by a swaged ferrule or by a hand spliced eye, the Liverpool splice being the usual method where a permanent eye is required, and heavy terminations are finished with a poured spelter socket. The rope is supplied to SANS 4309, and slings are built to order across the 6 mm to 56 mm range.

Factor of safety and certification

Steel wire rope slings carry a 6:1 design factor, meaning the minimum breaking load is six times the working load limit. This is the statutory factor for steel wire rope slings under Driven Machinery Regulation 18. Cable laid grommet slings are a separate product and carry an 8:1 factor. Slings fall within Toco’s registered LME 008 testing scope and are supplied tested and certified with full traceability, with the scope of testing and certification to be advised on enquiry. Under DMR 18, lifting tackle in use must be thoroughly examined at intervals not exceeding three months by a competent person. A wire rope sling is not repairable, but undamaged hardware can be reused and Toco recertifies slings that remain serviceable.
