ABSTRACT:
A lift and tilt table has a two arm linkage between the load bearing deck and the base. A single extensible cylinder acting between one of the arms and the deck causes the arms to rotate as the cylinder is extended to lift and tilt the table relative to the base. A pivotal connection between one of the arms and the base is slidable along the base from a forward position to an intermediate position and can be locked in the forward position. When the pivotal connection is locked, extension of the cylinder will cause the arms to rotate to simultaneously tilt and lift the deck relative to the base. When the pivotal connection is unlocked, extension of the cylinder will cause the arms to rotate to sequentially tilt and then lift the table relative to the base.
