ABSTRACT:
A leveling device for a lifting apparatus having a load-carrying member includes a level arm-carrying member and a pair of leveling arms having a first end pivotally connected thereto that are independently moveable between extended and retracted positions. The leveling device also includes a level sensor carried by the load-carrying member, and a controller in communication with the level sensor. The controller moves the leveling arms between the extended and retracted positions responsive to the level sensor sensing the load-carrying member being out of level.
