Abstract: A work vehicle (1) comprising a forward part (3) and a rearward part (7) pivotally coupled about a main vertical pivot axis (10) for steering thereof. A power take-off shaft (29) is located adjacent a forward end (31) of the forward part (3) and is mechanically driven from a main output drive shaft (15) of an engine (14) located in the rearward part (7). A step-up gearbox (20) steps up the speed from the main output drive shaft (15) onto first and second output shafts (23, 24) for driving first and second hydraulic pumps (27, 28) which provide hydraulic supplies for motive power and for operating attachments attached to the forward end (31) of the forward part (3). A step-down gearbox (30) receives drive directly from the main output drive shaft (15) of the engine (14) and produces a stepped-down drive on an output shaft (33) of the step-down gearbox (30) with a gear ratio of 2:1.

Abstract: An attachment (60) for a wheeled work vehicle (2) for clearing snow comprises a support housing (3) which rotatably carries an elongated cylindrical brush (5) and a plough blade (4), with the plough blade (4) and the brush (5) alternately operable between a lower operative state and an upper inoperative state. End elements (62) are pivotally coupled about vertical pivot axes adjacent respective opposite ends (15,16) of the plough blade (4). The end elements (62) are pivotal about a main vertical pivot axis (64) between a plurality of forward and rearward states through respective outward states. A coupling mechanism (7) couples the attachment (1) to the wheeled work vehicle (2) so that the support housing (3) is slewable between a transverse state and respective maximum offset states.

Abstract: A pressure compensated shear seal solenoid valve for use in subsea control systems is disclosed utilizing an arcuate cross section fluid passageway to improve flow rates, ease of serviceability and reduce size.

Abstract: A hydraulic drive system incorporating a hydraulic pump for three wheeled vehicles such as “piggy back” forklifts in which there are at least two separate but linked drives forming one drive unit for each of the wheels and each drive has a separate input and output. Valving is provided to provide both parallel and series operation of the system for optimum torque, speed and anti skid operation. In one preferred way of carrying out the invention a single drive unit feeds one of the drives of each of the other drives. The hydraulic pump feeds the single drive unit and one of the drives of the other transverse drive units. By-pass diverter valves are fitted across the drives of the transverse drive units.

Abstract: A crash bar assembly for a vehicle having an auxiliary equipment carrying mode with, for example, a forklift extending beyond its rearmost portion. The impact absorbing bar forming part of the assembly is movable outwardly to adjacent the rearmost end of the forklift on bars in sockets. A forklift may have a crash bar assembly mounted on itself.

Abstract: A universal forklift truck mounting frame (1) for fitting at a rear end of a carrier vehicle chassis has a composite base support framework. The base support framework has a rear support beam (8) and a front support beam (20) interconnected by a pair of spaced-apart hanger plates (5). Each hanger plate (5) has a flanged upper end (6) to provide a laterally extending chassis engaging surface. A wheel rest plate (9) is mounted at each end of the rear support beam (8). A pair of fork support sleeves (18), each for engagement with a fork of a forklift truck are mounted on the support framework between and substantially parallel to the hanger plates (5). A crash bar (10) is mounted at a rear end of the hanger plates (5).

Abstract: A three-stage mast (1) for a forklift truck and a forklift truck incorporating the mast (1). The mast (1) has an outer mast section (2) for mounting on the truck. A middle mast section (5) is slidably movable on the outer mast section (2) by rams (7). An inner mast section (12) is slidably mounted on the middle mast section (5) and carries a fork carriage (14). Lifting chains (20) and lowering chains (30) extend between the inner mast section (12) and outer mast section (2) passing over intermediate guides (24, 31) on the middle mast section (5). The chains (20, 30) raise and lower the inner mast section (12) on the middle mast section (5) when the rams (7) are operated. Similarly lifting chains (26) and lowering chains (34) extend between the middle mast section (5) and the fork carriage (14) via guides (27, 35) on the inner mast section (12) for movement of the fork carriage (14) on the inner mast section (12).

Abstract: Disclosed is an apparatus for removing fence posts and related posts form the ground or other media. The invention is designed to be used primarily with tractors and any other mechanical devices fitted with a three-point hitch and capable of lifting the three-point hitch and attachments. The machine includes two gripper blades arranged in V-shaped pattern and pivotally attached to a substantially pyramidical structure. When the post is gripped by the gripper blades, lifting of the base frame causes the gripper blades to pivot downward into the post. Further use of lifting force from the tractor or other related machine lifts the post out of the ground. After the post is removed from the ground, the post can be placed on the ground by lowering the apparatus which allows the post to drop at no greater angle than the arc created by the V-shaped opening formed by the gripper blades and the housing.

Abstract: The present invention relates to a new and improved trailer for unloading large cylindrical bales of hay. The trailer has a simple rectangular frame that holds hay bale carriers in place by a dual latch/keeper assembly mechanism. The dual latch/keeper assembly allows the cradle to tilt in either lateral direction to dump the hay bales on either side of the trailer. As a safety factor for the operator, the release for the latch/keeper assembly is on the opposite side from the side upon which the carrier dumps. The present invention may include a pedestal which holds a hay bale cradle over the wheels. The pedestal is removably mounted so that both the pedestal and the pedestal cradle can be removed thereby allowing the trailer to carry goods other than hay, such as irrigation pipe. The raised pedestal also allows for fenders over the wheels of the trailer. Fenders and lights are provided to ensure that the trailer is street worthy.
