Abstract: In conventional vehicle cranes it is usually necessary in consideration of current safety regulations to provide at least two separate steering circuits for all steered axles so that, in the event of a failure of one circuit, the vehicle crane can continue to be steered by way of the other. In order to avoid that in accordance with the invention at least one steered rear axle of a vehicle crane (1) is provided with a caster (a) so that at least one axle (11-16), in the event of a steering failure, remains steerable passively by utilising the caster friction. That principle is applied in a similar manner to a module axle (2) which can be mounted to the vehicle crane (1) and which can be required for transporting additional equipment or an additional counterweight which is possibly required.

Abstract: A bottle decasing, breaking and separating system and method has a hopper feeder for receiving bottles and cases. The bottles and cases are supplied to a trommel by a conveyor beneath the feeder. A conveyor communicating with the trommel receives the separated and fragmented material. A chute connected to the conveyor transports the fragmented material. Lifting tubes in the trommel are for lifting, tipping and tumbling the cases and the bottles in the trommel when it rotates. Strong screens in the trommel fragment and remove the bottles tumbling in the trommel. The cases remain at upper levels above the fragmented material in the trommel. The trommel may be a drum which slopes downward and rearward from the forward to the rearward ends. A trough below the trommel receives the fragmented material from the trommel and supplies the material to a conveyor. An extension communicating with the conveyor for supplies the fragmented material from the conveyor to recycling bins.

Abstract: A forklift having a frame supported by front and rear wheels is mounted on a carrier by inserting its forks into pockets mounted on the frame of the carrier vehicle and lifting the wheels of the forklift off the ground. A pair of wheel abutments on the underside of the carrier serve as abutments for the front wheels of the forklift to prevent its forward movement. A combined lock and support structure connected to the frame of the carrier prevents separation of the forklift from the carrier after the hydraulic system of the forklift is neutralized and all pressure on the forks, carriage, and mast are relieved of support forces.

Abstract: Screen panels are arcuately distorted and wedged between lifter tubes inside of trommels for varying the orifice size, shape or distribution or repairing drum screen sections in trommel screen separators. In lieu of replacing screens on the drum framework, the drum is ordered with the largest screen opening for the anticipated application. Additional screen panels are inserted or laminated to the original drum screen to reduce or change screen openings and to produce the smaller fines. Because these small screen panels receive structural support from the drum screen, quick change screen panels can be fabricated out of many different frames, screening materials and screen opening sizes. In preferred embodiments, the smaller, lighter, framed screen panels are easily managed and quickly exchanged as required, reducing downtime and loss of production. Quick change screen panels have resilient arcuately bendable semi-rigid frames and are designed to be handled manually.

Abstract: An improved cross-stiffened panel structure, such as used on bridges, load bearing floors, large haulage containers and dump trucks, is composed of a deck plate to which are attached a plurality of spaced apart stiffening ribs. A plurality of transverse beams, each having a cut-out shaped to fit over the external contour of the stiffening ribs, are welded to the deck plate except at the cut-outs. The cut-outs are dimensioned so that a nominal gap is maintained between the cut-outs and the stiffening ribs. In another embodiment, saddles are fabricated to fit over the stiffening ribs and welded to the deck plate while maintaining a nominal gap between the stiffening ribs and the saddles. The transverse beams cut-outs conform to the contour of the saddles and the transverse beams are welded to the deck plate and the saddles.
