  • Patent number: 5601014
    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.

  • Patent number: 5400720
    Abstract: A lift and tilt table including an upper platform which is raised and lowered over a lower platform. A table is provided over the upper platform and at one end thereof is adapted for only horizontal movement over the platform. A pair of arms and a pair of selectively actuated hydraulic cylinders are pivotally connected between the upper platform and the table. Actuation of the hydraulic cylinders causes the table free end to be lifted above the platform while the table is caused to simultaneously move in a horizontal direction for retaining the center of gravity of the table generally over the same area on the platform. An apron is provided on the table for preventing articles placed on the table from sliding off therefrom and the apron moves horizontally with the table so as not to extend over the edge of the platform.
