How accidents occur
The image on the right is a well known heavy-duty tow ball mount or towbar tongue.
Rated to 3.5t, a welder used an oxy torch to neatly enlarge the hole size to 32mm to fit o a 4.5t tow ball.
If you look closely at the piece wedged in the tow ball, you can see how much steel was towing his 4500kg rig.
The customer was as white as a ghost when I spoke with him.
We replaced this broken equipment with “fit for purpose” equipment rated at 4.5t.
Question: Is your 70mm tow hitch pin rated?
Compliant to Australian Standards.
Cast Tow Bar receivers are Class IV or 4 tonnes depending on the rating of your equipment.
