Abstract

A lift device includes a base, an arm, a drive actuator, a tractive element, and a steering actuator. The arm has a base end coupled to the base and a tractive element end. The arm includes a steering actuator interface positioned along an exterior surface of the arm. The drive actuator is pivotally coupled to the tractive element end of the arm. The tractive element is coupled to the drive actuator. The steering actuator has a first end coupled to the steering actuator interface and an opposing second end coupled to the drive actuator. The arm includes a plate extending forward of the exterior surface of the arm and past the steering actuator.
