ABSTRACT:
This vehicle includes a frame having inboard rail bearing wheels and outboard carriages carrying ground bearing wheels. The carriages are mounted to opposite sides of the frame for vertical movement in a guide system provided at each side of the frame and each carriage provides a mounting for fore and aft ground wheels. A counterbalance system is used to facilitate raising the carriages independently of each other from a ground engaging mode to a retracted mode and a latching system holds the carriages in place in each mode.
