Hello LoneRangie,
A boilermaker mate of mine used to build trailers for a living before he retired. He told me not to weld draw bars across the width of channel along the front edge of the trailer's box.
Over a period of time it forms a stress line and my mate frequently had RACQ drop of trailers that needed to be repaired after they snapped their draw bar off level with the front of the trailer box. All that is left is a draw bar on the safety chain and the box with its wheels rolling along unfettered. :o
I also saw a similar thing happen to a builder's trailer that was fully loaded on a two lane country road. Luckily the driver had the road to himself at the time :eek:. I just came along behind after he had pulled up and got out of the ute and the dust had settled.
Kind Regards
Lionel
