How accidents occur

The image on the right is a well known heavy-duty tow ball mount or hitch receiver.

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 4.5t rig.

The customer was as white as a ghost when I spoke with him.

The incident has just happened, The driver had his $40,000 rig @ 4.5t swaying on his safety chains.

We replaced this broken equipment with “fit for purpose” equipment rated at 4.5t.
