Abstract
Bodies for hook lift shuttles and other roll-off loaders are fitted with trailer towing hitches, such as fifth wheels and hitch balls, so that when one of these bodies is loaded onto a shuttle or loader, the shuttle or loader can be used temporarily as a tractor for a trailer. Means are provided for connecting truck utilities such as brake air and electricity to the invention and thence to a trailer.
