ABSTRACT:
In a material handling machine having a turret, a boom supported by the turret for movement about a first pivot, and a piston-cylinder unit for pivoting the boom about the first pivot, the piston-cylinder unit being supported by the turret for pivotal movement about a second pivot parallel to the first pivot, the improvement comprising at least one of the aforesaid pivots being journalled for rotation in the bore of an eccentric sleeve member which is in turn journalled for adjustable rotation in the turret. Rotation of the eccentric sleeve produces a change in the distance between the first and second pivots, with an accompanying variation in the speed-power relationship of boom movement.
