Abstract:
A vehicle dislodging system for a vehicle with a longitudinally extending vehicle frame, the system comprising:a first arm comprising a first elongated section with opposing ends and a second elongated section with opposing ends, one of the ends of the first elongated section pivotally connected to one of the ends of the second elongated section, the other end of the first elongated section pivotally connected to the vehicle frame for rotational and longitudinal movement with respect to the vehicle frame;a drive system connected to the frame and to the first arm, the drive system moving the first arm in a longitudinal direction with respect to the vehicle frame and at substantially the same time in a vertical direction with respect to the ground surface so that the first arm is moved from a resting position adjacent the vehicle frame to an engaging position with a ground surface to move the vehicle longitudinally and at substantially the same time to lift at least a portion of the vehicle off of the ground surface; andan assembly connected adjacent the pivotally connected ends of the first and second elongated sections, the assembly having an encumbered position where the second elongated section is restricted from moving past a first fixed position in at least one longitudinal direction and an unencumbered position where the second elongated section can move past the first fixed position.
