Abstract: A tool bar and hydraulic system for a large scale agricultural implement. The tool bar includes opposed pivotable wings that are extended in a field configuration and retracted in a transport configuration. In some embodiments, each pivotable wing includes two lift assist assemblies for aiding in the execution of turns in the field, and for aiding in the transport of the agricultural implement. The tool bar may be configured to compensate for twist of the pivotable wings when in the transport configuration. The hydraulic system is configured to stiffen the tool bar assembly for lift assist during field operation and to flex the tool bar into a folded configuration for transport.

Abstract: A tool bar and hydraulic system for a large scale agricultural implement. The tool bar includes opposed pivotable wings that are extended in a field configuration and retracted in a transport configuration. In some embodiments, each pivotable wing includes two lift assist assemblies for aiding in the execution of turns in the field, and for aiding in the transport of the agricultural implement. The tool bar may be configured to compensate for twist of the pivotable wings when in the transport configuration. The hydraulic system provides a “stiffening” of the tool bar for lift assist during field operation while providing for flexing of the tool bar during transport.

Abstract: A tow bar-activated brake system capable of engaging two tires or tire sets of a dolly or trailer where the tires or tire sets are of substantially different diameter. The system includes a first brake assembly and second brake assembly commonly actuated yet capable of rotating independently of each other to provide engagement with both tires/tire sets, even when the tires/tire sets are of substantially different diameter, for example due to uneven wear.

Abstract: A munitions trailer for transporting long bodied munitions items such as bombs and missiles from a storage location to a flight line for loading on a combat aircraft. The trailer has forward, middle and aft decks. The forward and middle decks are separated by a forward deck opening. The middle and aft decks are separated by an aft deck opening. The middle deck can be divided into forward and aft middle deck sections separated by a middle deck opening. The deck openings are covered by sets of doors. In the closed position the doors cover the deck openings whereby a flat main deck in available for general transport purposes. The main deck is convertible to one of a choice of open deck configurations by opening one or more of the door sets. When a door set is opened, the deck opening that is uncovered provides clearance for loading and unloading of long bodied munitions items from the deck.

Abstract: The stowable shelf bag cart of the present invention includes a base portion resting on a wheeled chassis. The base portion includes a fixed lower shelf. A frame extends upwardly from the base portion, and includes four upright corner members connected at their upper ends by four lateral braces. The two ends of the cart are enclosed by end walls and a cover extends over the top of the cart. A stowable shelf is placed approximately halfway between the base and the top of the frame. The shelf includes axial projections at both ends that glide within a track fixed to each end wall. One other projection is located at each of the four corners of the stowable shelf. These projections are slidably received in tracks that are integral with the four upright corner members above the level of the stowable shelf. Latches are provided that securely lock the stowable shelf in the shelf position, yet permit the shelf to be easily adjusted to a right or left side wall position by one person without using any tools.
