Patent ID: 8459925

Claim:
A device for moving a tilt frame in relation to a transfer bed capable of adjusting to varying heights, for use in transferring cargo between a vehicle and a loading ramp of varying height, the device comprising: a table supported by the tilt frame and mounted on a substantially horizontal axis, the table having a first surface configured to permit coaxial rotation of an opposing second surface located on the transfer bed, and the table capable of rotating about a substantially horizontal axis that is substantially perpendicular to a longitudinal axis of the tilt frame; a spherical bearing participating in connecting the tilt frame and the opposing second surface of the transfer bed, the spherical bearing comprising a pin, a bearing base, and a bearing plate, wherein the transfer bed rotates about the pin and is supported at least in part by the bearing plate, enabling the transfer bed: (1) to rock side-to-side, about a substantially horizontal axis extending parallel to a longitudinal axis of the transfer bed, relative to the table; (2) to be oriented generally parallel to the ground during inclination of the tilt frame; and (3) to pivot laterally in a side-to-side fashion about a substantially vertical axis passing through the spherical bearing.
