    Abstract: A construction machine includes a system and method for performing a lockout or stand down of the machine to prohibit movement of the machine or one or more components of the machine, without shutting down the machine. Information about the status of the machine or a component thereof can be collected and relayed to an electronic control module (ECM) to determine whether to lockout the construction machine. If appropriate, the ECM can command lockout to an electrical component of the machine or component to prohibit movement of the machine or component until the lockout is released.

    Abstract: An articulated work machine includes a frame assembly having a front portion and a rear portion; an articulation joint connecting the front and rear portions and adapted to allow pivotal movement about the articulation joint by the front and rear portions; a plurality of front wheels attached to the front portion and a plurality of rear wheels attached to the rear portion; a brake associated with each of the front wheels and rear wheels; a steering sensor adapted to provide a steering signal from a steering mechanism of the articulated work machine; and a controller adapted to receive the steering signal, and wherein when a braking force is applied to the front and rear wheels when the controller receives the steering signal, the controller produces a signal to modulate the braking force to allow the front portion and rear portion of the machine to articulate without the machine moving forward.
