Abstract
A scissor lift mechanism for use on a coil car or the like, the lift having scissor legs connected to each other by a shaft. The lift is raised and lowered by a means for providing a generally vertical force to the shaft. The means may be provided by a hydraulic cylinder and a bell crank mechanism. The bell crank mechanism redirects the force from a hydraulic cylinder to a generally vertical force on a hinge connecting the scissor legs of the lift. The bell crank mechanism allows the strength of the lift to be maximized while retaining a low profile design.
