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. The improved roll-away combination taught herein comprises a particular form of mating between at least one horizontally and longitudinally disposed flange and guideway, on the lift table, and an engaging wheel contact means, on the wheeled truck. The present invention teaches a manner of allowing such a modified wheeled truck to be easily positioned upon said lift…
