A lift crane includes a carbody and movable ground engaging members mounted on the carbody. A rotating bed is rotatably connected to the carbody and includes a counterweight support frame including a rack coupled directly to a lower surface of the rotating bed. A boom is pivotally mounted to the rotating bed. A counterweight unit movement device is configured to move the counterweight unit toward and away from the boom. At least one auxiliary member includes a counterweight pad that is configured to not touch the ground during a pick, move, and set operation. A linear actuator is configured to adjust a distance that the counterweight pad is above the ground.
