Abstract
A scissor lift that achieves enhanced vertical travel of the deck for a given amount of horizontal travel of the legs. The enhanced vertical travel is achieved by overlapping the deck pivot point (i.e., the point at which a leg is pivotally connected to the deck) with the frame pivot point (i.e., the point at which a leg is pivotally connected to the frame) when the deck is in the fully lowered position. That is, the deck pivot point is lower than the frame pivot point when the deck is fully lowered. The pivot points can occur on the same leg or on different legs. The deck and frame pivot points can provide purely pivotal movement or a combination of pivotal and some other type of movement (e.g., translational movement). The above-described scissor lifts can be utilized to perform corresponding methods of lowering a scissor lift. In the method, the deck pivot is positioned lower than the frame pivot when the deck is in the fully lowered position.
