Important: Select the correct pintle hitch from our D-Value calculator below. Example, kN of Pintle Hook and other towing equipment correctly matches your vehicle and trailer.
D -Value for pintle hitches has long been a mystery for many when selecting the right size pintle hook. D-Value is maximum horizontal load in kN given to a pintle hook.
D -Value for Pintle Hooks is critical when selecting the correct pintle hook because depending on your truck and trailer weight, the D-Value is changing.
“So I think I need a 10t pintle hook because I am towing an 8t trailer with a 20t truck.”
The manufacturer states he does not have a D-Value. (in this case, you cannot use this pintle hook with no D-Value).
The cost to test equipment is a significant expense, sometimes up to $30,000. The purpose of testing is to provide a safe and reliable product. ADR62/02 regulations determine product safety.
D-Value and in some instances V-Value tests must be satisfactorily completed.
D-Value is the result of dynamic testing (2,000,000 cycles at full load) where a maximum value applied to the pintle hook. In case of a Couplemate 10t pintle hook, the D-Value is 49kN.
Now review our Min requirements for D-Value and select your truck GVM and Trailer ATM.
You also may wish to choose a ring coupling to install on your trailer. Ring couplings fall into the same equation. If it does not have a maximum D-Value, then you cannot calculate the correct towing combination.
Couplemate has tested it 3″ ring coupling to 49kN. From the table above, it is easy to calculate the correct towing configuration.
