Abstract
A lift table that consists of a base and a table attached on the right and left by pairs of scissor links. The table is raised through the use of a compression spring. The spring is compressed through the weight of the load on the table, thus creating a lift table which maintains a set height for the load on the table. The spring is positioned with one end attached to either the top or bottom end of one of the pair which form the scissor-link mechanisms, and with the other end connected to the other link, which intersects the first. One end of the spring is attached to a screw slider mechanism which is adapted to move along the length of the second link.
