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?

Steel chain is worked to a 5:1 factor of safety under DMR 18 of the OHS Act — the statutory figure that governs what is published in South Africa. This is the basis on which Toco rates and certifies the chain it supplies. 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. Toco’s long-link and extra-long-link chain is manufactured to SANS 251, the South African standard for long-link and extra-long-link general-purpose steel chain.

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.

Frequently Asked Questions

Can Grade 30 chain be used for overhead lifting?

No. Grade 30 is a general-purpose mild steel chain intended for securing, restraint and general industrial and agricultural use, not for overhead lifting. Overhead lifting requires heat-treated alloy chain such as Grade 80 or Grade 100. Toco supplies both and can advise on the correct grade for your application.

What is the difference between long link and extra long link chain?

Long link chain has an open link pitch that sits between short link and extra long link forms. Extra long link has the most open, longest pitch, suited to passing over a profile or coupling on site; long link is a little more compact. Both are supplied by Toco; the right choice depends on the application.

What factor of safety does Toco apply to steel chain?

Toco works steel chain to a 5:1 factor of safety, the statutory figure under DMR 18 of the OHS Act in South Africa. The chain is rated and certified on this basis. For alloy lifting chain a different factor applies, and Toco confirms the correct rating per grade on enquiry.

Does Grade 30 chain come with a certificate?

Yes. Toco supplies Grade 30 chain with a Conformance Inspection Certificate, the correct certificate type for lifting tackle that cannot suspend or halt motion on its own. Toco is registered as LME No. 008 and issues certification matched to the equipment class.

What sizes and working loads are available?

Grade 30 long link chain is stocked in a range of sizes; the available diameters, lengths and working loads are confirmed on enquiry so we match the chain to your duty correctly. Contact the Toco team with your application and load requirement for current stock and ratings.

Does Toco supply other chain grades?

Yes. Toco is a distributor of a broad chain range — general-purpose mild steel grades through to Grade 80 and Grade 100 alloy lifting chain and stainless steel chain. Speak to our team about the grade, size and certificate type your application requires.
