How Does a Pintle Hook Work?

  • Attain Trailer Weight
  • Attain Truck GVM
  • Select the correct D-value from the chart below
  • Install the Pintle Hook into the 85mm x 45mm hole spacings.
  • Failure to select the correct D-Value to match your truck/trailer combination will result in excessive component wear.

Attach couplings to a tow bar or directly to the truck chassis via standard mounts (85mm x 45mm).

Couplemate assures purchasers that pintle hooks and other towing equipment are rigorously engineered and tested to the National Australian Vehicle Standards.

Standard American Equipment (SAE) does not satisfy Australian Standard testing requirements.

The Couplemate unique Gold Head is a great indicator the pintle attachment is appropriately tested and certified.

D -Value for Pintle Hooks

The towing capacity of pintle hitches has long been a mystery to me when selecting the proper pintle hitch.

Towing capacity for Pintle Hooks is critical when selecting the correct pintle hook because the towing capacity changes depending on your truck and trailer weight.

Mismatched towing components wear and break prematurely.

Finally, the hitch rating is a force measurement due to dynamic testing (2,000,000 cycles at full load) where maximum pressure is applied to the pintle hitch. In the case of a Couplemate 10t pintle hook pintle ring on the right-hand side image, the “D-Value” is 49kN.
