Abstract

A lift device includes a chassis, a platform configured to support a user, a lift assembly coupling the platform to the chassis, an actuator configured to at least one of (a) move the platform relative to the chassis or (b) propel the chassis, a sensor assembly, and a controller. The sensor assembly includes a bar including a first end portion coupled to the platform and a second end portion opposite the first end portion and a housing defining an aperture sized to receive the second end portion of the bar. The sensor provides a signal in response to at least one of (a) the second end portion of the bar contacting the sensor or (b) the second end portion of the bar exiting the aperture. The controller is operatively coupled to the sensor and the actuator and configured to control the actuator based on the signal from the sensor.
