An automatic leveling device includes a motor mounted onto a frame, a linear actuator coupled to the motor, and a slideable bail assembly coupled to the linear actuator. The bail assembly is attached to the frame. The frame is configured to attach to a lifting beam, which is attached to a load surface. A controller assembly has a sensor configured to determine an orientation of the load surface when the load is suspended. The controller assembly is configured to automatically control the motor in order to position the slideable bail assembly such that the load is suspended in a predetermined orientation.
