For trailers up to 3500 kgs ATM (steel chain to AS4177)

Chain used in trailers up to 3500 kgs ATM must comply with Australian Standard AS4177 Caravan and light trailer towing components - Part 4 Safety chains up to 3500 kg capacity. The size of chain according to trailer ATM is specified in Table 1 below.

If the chain is to be welded to the drawbar, the weld must cover at least 50% of the length of the link and the adjoining link must be able to move freely within the welded link. Alternatively a plate may be welded to the drawbar and suitably rated fittings such as Hammerlock fittings may be employed.

 

Markings Complying chain is permanently and legibly marked with the manufacturer’s or importer’s identification and the digits 4177 (i.e. the number of this Australian Standard), followed by a hyphen and the first two digits of the chain load designation. For example, chain with a breaking load of 2500 kg will be marked 4177-25. The marking on complying chain is repeated at intervals not exceeding 4 links and the characters on the links are at least 1.5 mm high for chains less than 8 mm link diameter, and not less than 2 mm high for chains 8 mm and above.
