Thank you for your comment and sharing your concerns about the appropriate equipment for ensuring road safety while towing. I would like to provide a more detailed explanation of our Trailer Safety Chain Hook Kits, including the relevant data, standards, and calculations to demonstrate their suitability for various towing applications.
Our hook kits are designed to comply with Australian Standards, specifically AS3775.2 and AS4177. These standards outline the requirements for the design, testing, and performance of chain and components used for load restraint and towing applications as per ADR6202.
CALCULATIONS REQUIRED BY ADR6202
Longitudinal Tension (N)= 9.81 x ATM (kg)
Vertical Tension (N)=0.5 x 9.81 x ATM (kg)
