Abstract
A tractor trailer is disclosed herein as including linkage structure for the tractor and the rear wheel chassis which are arranged to connect to a trailer bed in the form of a pallet. The pallet is constructed to sit upon the ground at a low height relative to the industry standard, easily mountable by workmen with climbing aids. The linkage structures are nearly identical and utilize hydraulic rams to raise or lower an end of the pallet and place or remove the same relative to their respective wheel chassis. Each of the linkage structures includes pins and link members, some of which may be interconnected to permit the raising and inverting of the rear wheel chassis and placing the same on the tractor chassis for transportation.
