Aggregate Trailer Mass (ATM) Calculator

ATM Calculators are provided to assist transport operators to help ensure their trailers are sufficiently rated. ATM is the rating for a trailer, referring to the maximum trailer mass. Transport operators are obliged to ensure their trailers are suitably rated for the load being carried.

Tow Coupling D-Rating Calculator

The D-Rating Calculator allows transport operators to check and ensure their tow couplings are sufficiently rated. A vehicle combination fitted with insufficiently rated tow couplings can result in catastrophic consequences. Disclaimer: The results provided by the calculators are only as accurate as the data that is inputted by the user. Each field in the ATM Calculators and the D-Rating Calculator must be completed for accurate results.

D-Rating Calculator

Trailer Clearance Calculator

The Trailer Clearance Calculator will assist transport operators to determine the minimum gap requirement between vehicles in a combination. The Australian Standards AS2174 requires the vehicle combination to have sufficient clearance to allow the trailers to move through all angles of articulation, pitch and roll.

Trailer Clearance Calculator

Static Rollover Threshold Calculator

The SRT Calculator helps transport operators to assess the rollover risk of their vehicle configuration and load. This then allows operators to either adjust the load accordingly or ensure there are suitable controls in place to mitigate the risks.
