Abstract
A scissors lift with a combination wedge and lever mechanism for switching between wedging action and lever action during lift operation. This device includes a scissors mechanism, a table, a wedging device, a lever device, and an actuator. The scissors mechanism connects to the table such that movement of the scissors mechanism correspondingly moves the table. The wedging device causes a lifting action as the scissors mechanism begins moving between a contracted position and an expanded position. After the lifting action, the lever device translational moves as the scissors mechanism continues moving between the contracted position and the expanded position. Finally, an actuator initiates the lifting device's movement between a contracted positioned and an expanded position by moving in a direction substantially perpendicular to the movement of the scissors mechanism.
