Difference between Pintle Ring vs Tow Eye

What is the difference between a Pintle Ring and a Tow Eye? This is a question we often get asked.

Both components mount onto the trailer drawbar and have a toroidal-shaped hole that connects to the tow vehicle.

Pintle Rings are far more common on the Australian market and often seen in conjunction with Pintle Hooks. Tow Eyes, on the other hand, are used with Ringfeders or Orlandi couplings; commonly seen on large tow trucks.

ADR Approved Pintle Ring Coupling

The CM255 Fixed Pintle Hook Ring Coupling falls under ADR 62 and has been granted a Component Type Approval (CTA-045953).

Buying a product with a CTA number assures customers that the product has been developed, tested, and presented to the market with no development or manufacturing corners cut. In a sense, a CTA assigns pedigree to a component, providing a testament of quality.

D-Values for Tow Trucks

The D-Value is a crucial metric that assesses the horizontal force-handling capability of a truck and trailer combination.

For example, if you have a GVM of 8500kg and an ATM of 4500kg, the minimum D-Value required is 29kN.

You can work out your D-Value using the calculator below or download our D-Value Guide.
