Hello
Here is my 5th wheel dolly that I have made.
5th wheel dollies allow a trailer that would usually be pulled by an articulated truck, to be pulled with a regular style tow hitch.
It is a very easy custom, as the chassis, drawbar and wheels all come from the mobile crane, and a 5th wheel is added from one of the artic trucks.
The 5th wheel has to be sanded down width ways to fit between the wheels, and then on the bottom, to provide a flat surface so that it can be glued on with strong plastics glue.
A real one:
Here it is in use with a tractor and bale trailer:

It has many uses:
Thanks for looking,
