Pintle Hitch Testing

Heavy Duty Towball testing at Couplemate

The Australian Standard requires 3.5t tow balls to be tested with a horizontal force of 85kN or approximately 8.5t.

Pintle Hook balls are rated to 3500kg. Higher ratings for 4500kg pintle hooks are not available at this time. However, they may be available at some point in the future.

Also, review combination pintle hook ball protectors to prevent excessive wear and tear.

How to Break a 3.5t Tow Ball

This is an excellent example of what can occur for trucks over 5t using 50mm Pintle Combinations.

Reversing a truck onto the ring coupling is not as easy as it seems.

Trucks crashing ring coupling into the tow ball will cause the tow ball to break.

Reversing into the ball causes shock loading of more than 3.5t and, more likely, 8.5t or more excellent.

Tow balls do not break unless used at loadings over the rating or incur shock loading.
