Grade 30 Long Link Chain

Grade 30 long link chain is a general-purpose mild steel chain supplied by Toco Lifting across South Africa for industrial, agricultural and load-securing applications. As a registered Lifting Machinery Entity (LME No. 008), Toco supplies the chain and issues a Conformance Inspection Certificate against a 5:1 factor of safety under the OHS Act.

Toco Lifting holds Lifting Machinery Entity registration LME No. 008 under the Driven Machinery Regulations of the Occupational Health and Safety Act, with technical oversight by Anton van Staden, an ECSA-registered Lifting Machinery Inspector (Reg. #201112078).

What is Grade 30 long link chain used for?

Grade 30 is a general-purpose mild steel chain, it is used for industrial and agricultural duties, securing and restraining loads, and general site work, rather than as an overhead lifting grade. The long link form has an open, longer pitch than short link chain, which suits applications where the chain must couple on site or pass over a profile, while sitting more compactly than extra long link. Toco supplies it as a distributor of a broad chain range alongside higher-grade alloy lifting chain.

What factor of safety applies to steel chain?

Grade 30 is rated at a 5:1 design factor, the manufacturer's design figure that Toco rates and certifies against. It is not a statutory requirement: under DMR 18 the statutory factors of safety apply to steel wire rope slings and cable laid grommets, not to general purpose chain. Grade 30 is a general-purpose grade and is not a substitute for Grade 80 or Grade 100 alloy chain where overhead lifting at higher working loads is required.

What certificate does Grade 30 chain carry?

Grade 30 chain is supplied with a Conformance Inspection Certificate. Under Toco’s certification taxonomy, items that cannot suspend or halt motion on their own, chain, slings, wire rope, shackles and lifting tackle, carry a Conformance Inspection Certificate, as distinct from the Performance (Load) Test Certificate issued for machines such as chain blocks and hoists. Toco issues the correct certificate for the equipment class under LME No. 008.

Long link versus extra long link and short link chain

Long link chain has an open link pitch that sits between short link and extra long link. Short link chain is compact and runs neatly over sprockets and through guides; extra long link has the most open pitch for passing over a profile or coupling on site; long link falls between the two. All are general-purpose grades supplied by Toco; the right choice depends on the application.

Grade 30 versus alloy lifting chain

Grade 30 is mild steel for general-purpose duty; Grade 80 and Grade 100 are heat-treated alloy chains rated for overhead lifting at substantially higher working loads. If your application is sling assembly or overhead lifting, alloy chain is the correct choice. If you need a robust, cost-effective chain for restraint, securing or general industrial and agricultural use, Grade 30 long link chain is well suited. Toco supplies the full range and can advise on the right grade for the job.

Applications

Grade 30 long link chain is used across mining, construction, agriculture and general industry for load securing, restraint, fencing and general-purpose site work. Toco supplies chain and lifting tackle nationally and across the SADC region.
