Galvanised Safety Chain on Trailers

Galvanised Safety Chain – 64cm long for 10mm chain and 64cm long for 13mm chain.

The caravan and trailer safety chain are essential in coupling failure between the vehicle and trailer. Worn tow balls and couplings are a major cause of coupling detachment from the towing vehicle.

made in australiaWe think you should know that this safety chain is made in Australia.

  • The Safety Chain rating is stamped every four links.
  • Two chains per trailer or caravan are mandatory on all trailers over 2.5t.

Is your trailer or caravan chain too short?

The solution

  • cut the trailer safety chain from your chassis rail, leaving only the welded link on your chassis.
  • Install a new piece of rated galvanised 13mm longer chain.
  • Connect the hammerlock to the new chain and the welded link on your chassis rail.

What you cannot do

  • Join multiple shackles until you reach the desired length.
  • Insert un-rated links
  • Use hooks on the trailer safety chain
  • Use bolts to attach the safety chain to the trailer

Galvanised safety chains and shackles are illegal on all trailers over 3.5t.

How many safety chains are required on a trailer?

  • One 10mm safety chain on trailers up to 2500kg.
  • Two 13mm safety chains on trailers up to 3500kg.

Why cross the trailer safety chains?

In extreme circumstances resulting from an accident or oversight, couplings become detached from the tow ball. Cross chains prevent the coupling from falling to the ground and catch the coupling in a chain cradle.

How should trailer safety chains be attached to the tow bar and trailer?

  • Attach chains to the tow bar via a rated dee shackle or bow shackle or other suitable rated connection.
  • Attach the chain to the trailer via a hammerlock to a chain holder or weld one link, horizontally to the trailer chassis rail.

It is essential to remember…

No chain welding below the chassis rails.

Trailers up to 2.5 tonnes ATM must have at least one safety chain complying with AS 4177.4 – 1994 (Trailer and light trailer towing components – Safety chains up to 3.5 tonnes capacity), or as amended from time to time. This standard allows for steel safety chains by the following:

  • to 1.0 tonne, a chain size of 6.3 mm
  • up to 1.6 tonnes, a chain size of 8 mm
  • up to 2.5 tonnes, a chain size of 10 mm
