  • Patent number: 4288195
    Abstract: A system for allowing a wheeled truck to be rolled on and off a vertically extendable lift table assembly, whereby material handling operations between one vertical elevation, and one horizontal location, and the second vertical location, at a second horizontal location, will be facilitated. The roll-away lifting combination herein essentially comprises a vertically extendable lift table assembly with a cooperating wheeled truck assembly that can be selectively superposed, i.e., moved on or off, a lift table assembly which in turn allows the entire assembly to be conveniently moved from one horizontal location to another. The lift table itself preferably has a double scissor-jack linkwork, which allows the wheeled truck to be raised, for example, to heights of approximately seven feet above a horizontal ground reference.
