Abstract
A lift device includes a chassis, tractive elements, a platform, a lift assembly, a first set of proximity sensors, and a controller. The tractive elements are rotatably coupled to the chassis and support the chassis. The platform is disposed above the chassis and includes a deck for supporting an operator. The lift assembly couples the platform to the chassis and can selectably move the platform between a lowered position and a raised position. The first set of proximity sensors are coupled to the platform and detect a distance of an obstacle relative to the platform. The controller is operably coupled with an alert system and receives obstacle detection data from the first set of proximity sensors. The controller selects a subset of the first set of proximity sensors to analyze based on an active function of the lift device and determines whether the obstacle is within the minimum allowable distance.
