ABSTRACT:
An apparatus for synchronizing the extension and retraction of linear actuators. A quadrilateral structure is formed by means of the support base, a pair of actuators, and a crossmember, with a sensor positioned so as to detect variations in the shape of the quadrilateral. The sensor functions in cooperation with the actuator control mechanism to vary power to the actuators in response to the changes in shape which occur due to slight variations in actuator speed of movement.
