Truck loses back wheels trying to turn around safety barriers - video

The design of those particular trailers is very weak, they are made light weight and for light bulk cargo and good roads only, no thru chassis to speak of at all. The base of the side walls is where the strength of the trailer is, and the rear wheels are just connected to light weight cross members. Something like this proves just how weak that design actually is. Another video doing the rounds, shows that same sort of trailer turning a corner and the side and roof of the trailer just collapses. Horses for courses and you only pay for what you get and this design is B-A-D.

And on top of that most have sliding tandems the axle set is only held in place by a couple of retractable pins on both sides Road spray from the tires wreck havoc on the mechanics of the pins when combined with the salts and chemicals used to rid the roads of ice and snow the whole thing is a short time from rotting away and or wearing out. But this is partially by design. Manufactures build trailer to sell, if trailers were built to last a long time they wouldn't be able to sell as many trailers.

Although previous observations and descriptions seem well-founded, I believe it's a cost cutting goal.

Many of our interstates tax vehicles by the number of loaded axles.

SO you are saying this was a deliberate attempt to reduce the vehicle tax rate by removing the superfluous axles. Brilliant

Well, yeah. It's not easy being world class cheapskate AND pro stick it to 'em grade.
