Truck trailer safety holders use 4140 high tensile pins only on vehicles that weigh over 3500 kg. These vehicles use Herc Alloy chains. National Heavy Vehicle Inspection Manual
The Herc alloy safety chain holder is an innovative solution to prevent the safety chain from dragging when attached to the towbar.
Installation:
- Weld the safety chain holder to the tow bar.
- Weld safety chain holders directly to the trailer chassis rail as close as possible to the coupling.
- The holder may also be welded to a plate which is affixed to the trailer via 4 x high tensile bolts. Example, in the case of aluminium trailers.
Testing Safety Chain Holders
Road safety starts with product safety and product testing.
Rigorous product testing is undertaken before the product is passed for the consumer to purchase.
The 200t press above is set up to destroy the safety chain holder to its breaking level and record the data.
Welding plays a crucial role in safety. Incorrect or unprofessional welding causes dangerous situations.
- Every truck with a tow bar tow a trailer over 3.5t must have attached to it a pair of safety chain holders.
- Mount the chain holders on either side and adjacent to the tow bar coupling.
- Furthermore, the attachment must be able to withstand static forces that incur during towing and in particular, be resistant to cracks or breaks.

Further, towbar safety chain holders differ to trailer mounted safety chain holders. Here is why:
- Firstly, the lynchpin to enables the pin to be removed and re-attached from the holder located on the towbar.
- Secondly, the trailer safety chain holder uses a split pin which is removed via the use of a tool.
