Wonderful machines and these people are talented. I wish to be one of them.  Very Impractical bit of tinkering with normal tipping semi-trailer configuration - What has been done to increase the ability of the prime mover to handle the increased load,  - What has been done to improve the trailer stability when tipping the extra weight, for example all the wheels should always have ground contact before the hoist can raise the load.  24 wheels are on the trailer  plus the 10 on the truck   That's 34!
