Abstract: A self-propelled cart which receives control signals from a remote electronic device. In some embodiments, the dumper includes a top portion and a lower portion, wherein the top portion and the bottom portion are rotatably coupled by a rotating member such that the top portion rotates independent of the base. In some embodiments, the top portion may rotate 360° about a vertical axis of the base. In one implementation, the dumper does not have a cab or onboard control station.

Abstract: A lift device includes a chassis, a platform, a lift assembly coupling the platform to the chassis, an actuator, 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, a receiver positioned to receive the second end portion of the bar, and a sensor configured to detect 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 receiver. The controller is operatively coupled to the sensor and the actuator and configured to control the actuator based on a signal from the sensor.

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.
