ABSTRACT:
A tilting mobile platform comprising a platform having an upper surface and a lower surface with a first and a second rail member securely fastened to the lower surface of the platform is disclosed. An axle supporting frame is slidably secured to the rail members. A first axle is rotatably attached to the axle supporting frame such that the axle is transversely mounted on the axle supporting frame relative to a path of movement of the axle supporting frame along the rail members. An axle supporting frame moving means moves the axle supporting frame along the first and the second rail members from a first position to a second position. The axle further includes a first and a second axle arm extending perpendicular to the axle and each axle arm further includes a stud extending substantially perpendicular relative to the axle arm and parallel to the axle. A first and a second ground engaging wheel is rotatably attached to each parallel stud for movably supporting the platform and the articles placed thereon. The platform includes a means to enable the platform to be moved along the ground. An axle rotating means rotates the axle such that in use when the axle is rotated the axle arms rotate from a first angle to a second angle and when the axle supporting frame is positioned at the second position, the platform defines a ramp position and when the axle is further rotated the axle arms form the first angle and when the axle supporting frame is positioned at the second position, the platform defines a hauling position.
