Abstract
A height control mechanism for a lift device includes an elongated rail and an actuator slidingly mounted thereto. The actuator is biased toward a first end of the rail, and a proximity sensor is mounted proximate the second end of the rail. A cable pulls the actuator toward the second end of the rail as the lift device is elevated. When the proximity sensor detects the presence of the actuator, a signal is generated to halt further elevation. The position of the proximity sensor along the rail can be adjusted to set the maximum height of the lift device. A second proximity sensor, responsive to the presence of the actuator, can also be secured to the rail to generate a signal indicating that the lift device has been elevated off of the ground by a short distance.
