Abstract
A leveling system for a lift device includes an axle, a pin, a cradle, and a chassis. The axle is configured to rotatably couple with one or more tractive elements. The pin extends through a bore of the axle. The cradle is pivotally coupled with the pin. The chassis is pivotally coupled with the pin and includes a first actuator and a second actuator. The first actuator and the second actuator each include a body and a rod configured to extend relative to the body. The rods of the first actuator and the second actuator are configured to be extended to engage corresponding surfaces on opposite sides of the cradle. The cradle and the chassis are configured to rock in unison a limited angular amount relative to the axle.
