Premium Combination Pintle Hook | Incl. High-Tensile Bolts

The Couplemate™ Premium Combination Pintle Hook is specifically engineered to enhance your towing experience and eliminate undue wear. With a heavy-duty design and focus on ultimate safety, this Combination Pintle Hook is the preferred choice in the Australian mining industry.

Most combination pintle hooks will use a 50mm ball when towing with a ring coupling, but the Couplemate™ Premium version means that your pintle ring will pull on a higher-rated cast iron body. This boosts safety, product lifespan, as well as eliminates slack and jolting movements when braking.

This component is suitable for towing with a ring coupling and a 50mm ball coupling, providing you with convenience and adaptability.

Made in our Brisbane warehouse, this Australian-made product is a great and safe solution for your towing needs.

Important Information

D-Values for Trailer Couplings

D-Values assign ratings to tow couplings. These values represent the maximum force that can be safely exerted on the component.

For example, 50mm ball couplings have a D-Value that is determined by:

• Maximum towing vehicle mass of 5000kg.
• Maximum trailer mass of 3500kg.

So, why are D-Values important? Failure to select the correct D-Value to match your truck and trailer combination will result in excessive component wear.

Use the Couplemate™ D-Value sheet, or the form above, to ensure that the kN of this Pintle Hook correctly matches your tow vehicle and trailer.
