How to Break a Tow Ball

This is a good 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 into the ring coupling with the tow ball will cause the tow ball to break.

The tow ball is rated to 3.5t. Crashing into the ball causes shock loading in excess of 3.5t and more likely 8.5t or greater.

Tow balls do not break unless they are used at loadings in excess of the rating or incur shock loading.
