ABSTRACT:
There is provided an over-translation sensing and centering apparatus for a scissors lift work platform comprising a linear cam arranged with electronic sensing means to detect an out-of-balance condition. For transmitting the relative angular position of the scissors members to linear movement of the cam, there is provided a control member pivotally mounted to the cam having bar links pivotally mounted to each extremity and connecting the control member to each scissors member. As each scissors member extends, the angle of the members with respect to the base of the vehicle causes the respective extremity of the control member to shift. As long as the scissors members move in equal opposing increments, the control member mounted on the linear cam rotates only, but if one member moves more than its counterpart, the control member is caused to shift and thereby move the linear cam. This movement is then sensed by microswitches and corrective action is initiated through responsive solenoids in the hydraulic lift circuit.
