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.
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. |
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.
Toco assembles and presses its own slings rather than buying them in. Seven hydraulic presses across Germiston and Cape Town cover rope from 1 mm to 56 mm, including a 1 500 ton press for 32 mm to 56 mm in Afgrip and Superloop, and slings are proof load tested on a 200 ton bench, 8 m, at Germiston on SANAS calibrated load cells. That is why a large diameter sling does not have to go out to a third party, and why traceability runs from the rope batch through to the certificate. See the press and swaging capability.
Steel wire rope slings supplied into South Africa 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. The international standard norm is 5:1, which is what applies on export specification, so confirm the destination market when ordering. 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.
Four steel wire rope slings and eye nuts, with chain attached at either end, were used to secure an estimated 10 to 15 tons of rock so that it could be removed safely by the Cape Town Metro. It is not a lift in the ordinary sense. It is restraint of an unstable mass while the work goes on underneath it, and the sling selection has to be right the first time.
Toco supplies wire rope slings across sectors, including the applications below.
| Industry | Application |
|---|---|
| Mining | Headgear and shaft rigging, plant lifts, and tower terminations |
| Construction | Lifting structural steel and plant, and tensioning work |
| Marine and offshore | Mooring, towing and rigging in corrosive conditions |
| Power and telecoms | Spelter socket terminations on power line and communication towers |
Toco serves these and other sectors. Tell the team the load, length and end fittings and they will specify a suitable sling.
Slings are made to order from 6 mm to 56 mm rope in single, double, triple and quadruple leg and eye and eye, with end fittings from eye formations to heavy duty hooks.
For slings supplied into South Africa, 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. The international standard norm is 5:1, which is what applies on export specification. Toco works to 6:1 as its norm, so confirm the destination market when ordering.
Yes. Slings are assembled in house, tested and certified within Toco’s LME 008 scope with full traceability, and the scope of testing and certification is advised on enquiry.
The rope itself is not repairable, but undamaged hardware can be reused, and Toco inspects, tests and recertifies slings that remain serviceable.
Under DMR 18, lifting tackle in use must be thoroughly examined at intervals not exceeding three months by a competent person.
Wire rope slings are lighter, lower in cost and suit long lengths, while chain slings are more durable, repairable and tolerant of extreme temperatures. Toco supplies and certifies steel wire rope slings across South Africa and into SADC, including Botswana, Zimbabwe, Zambia, Mozambique, Namibia, Eswatini and Lesotho.
