ABSTRACT:
This invention relates to an improvement in a wheeled vehicle upon which is mounted a crane or fork lift. More particularly, this invention relates to a wheeled vehicle for conveying loads including a machine bed upon which are mounted three wheel fitting yokes, one rear and two front, to which wheels are respectively attached in the rear center and both front sides of the machine bed as to revolve freely and independently. For steering purposes, an oil pressure power cylinder is connected to each of the wheel fitting yokes through a rack and pinion gear and for locomotion an oil pressure motor furnishes power to the wheels. The wheels may be moved along a circle which passes through the point of ground contact of each wheel, thereby rotating the wheeled vehicle about a circular path centered near the middle of the vehicle. Alternatively, the wheel fitting yokes may be oriented for sidewise motion of the wheeled vehicle.
