ABSTRACT:
A crane leg connection is disclosed in which a crane has a frame length greater than its width, and has supporting legs including facing leg members connected to the frame and extending from the frame downward and away from each other and away from the frame in a direction transverse to the length of the frame. A support beam is mounted on the frame, and at least one of the leg members is connected to the support beam. A support arm connects the support beam and the frame together and carries the vertical load on the frame and transfers that load through the support beam to the leg. The support arm is connected to the support beam and frame such that the leg and frame are movable relative the each other transversely to the length of the frame. Another arm is affixed to at least one of the leg members and extends toward the frame, and an arm affixed to the frame extends toward the arm affixed to the leg member. A link means connects the arms affixed to the leg member and frame together in a movable manner such that the frame and leg member are movable relative to each other.
