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.

A cab support assembly supports and moves an operator's cab relative to a frame of a construction machine. The cab support assembly includes a cab support coupled to the frame of the construction machine. The operator's cab is mounted to a cab support mounting frame, which in turn is pivotably coupled to the cab support. An actuation device is coupled to the cab support and to the cab support mounting frame. The actuation device includes a first actuation device position in which the cab support frame is in a first position in which the cab support mounting frame defines a first plane, and at least a second actuation device position in which the cab support mounting frame is in a second position such that the cab support mounting frame defines a second plane that intersects the first plane at a negative angle.
