Abstract

See full text

The scissor lift includes a horizontally collapsible base, a vertically collapsible frame mounted on the base, a horizontally foldable platform mounted on top of the vertically collapsible frame, and a plurality of wheels mounted on the base. The horizontally and vertically collapsible scissor lift is steerable and the plurality of wheels may be coupled such that they each rotate about a vertical axis synchronously with respect to one another to steer the lift. Further, at least one of the wheels may be self-driving to controllably propel the horizontally and vertically collapsible scissor lift. One or more winches with associated cables may be used to selectively raise and lower the vertically collapsible frame.
