A mobile lift crane includes a carbody, movable ground engaging members, a rotating bed, and a boom. A first structure is pivotally coupled to the rotating bed. A second structure is pivotally coupled to the first structure at a first end of the second structure. A moveable counterweight unit is coupled to a second end of the second structure. A linear actuation device moves the moveable counterweight unit toward and away from the rotating bed during a pick, move, and set operation by retracting and extending the linear actuation device, respectively. The moveable counterweight unit is never supported by the ground other than indirectly by the moveable ground engaging members. The linear actuation device moves the movable counterweight unit a greater horizontal distance from the rotating bed than a distance of a stroke of the linear actuation device that causes the moveable counterweight unit to move.
