Abstract: A wheeled carrier for manual movement of material includes a base frame with a pair of frame rails. The frame rails are turned down at the front end with a first bracket connecting the rails and providing a mounting point for at least one wheel and a receiver between the frame rails. The wheel is positioned so that it does not extend above either of the frame rails. A second bracket extends between the frame rails and includes a release mechanism positioned between the frame rails. An attachment including a yoke may be releasably mounted to the base frame. The yoke extends between the receiver of the first bracket and the release mechanism of the second bracket and engages the receiver and the release mechanism. The attachment further including a load carrying arrangement configured to rest on the frame rails above the at least one wheel without engaging the wheel.

Abstract: A pivotable fold-down step system mounted to a vehicle, such as a fire truck or rescue truck, and synchronized to extend and retract by vehicle door motion. The step system is designed to easily achieve ingress and egress requirements stated within the National Fire Protection Agency (NFPA) guidelines. The step remains sealed and contoured to the vehicle profile when in the upright stowed position when the vehicle door is closed. The fold down step is operated by means of a pressurized fluid system which is integral to the vehicle. As the vehicle door opens the step is extended downward, under pressurized control, to allow for rapid and safe egress from the vehicle. As the vehicle door closes, the step is again operated by the pressurized integral fluid system and the step rises and folds into a stowed position within the vehicle body prior to transport of the vehicle.
