Abstract: A system mounted on a powered industrial vehicle for detecting classifying and tracking in real time at least one obstruction in the scene around the vehicle. The vehicle is capable of moving in multiple directions. The system includes a multiple cameras mounted on the vehicle, wherein the viewing zones viewed respectively by the cameras preferably encompass 360° horizontally around the vehicle. Each of the cameras is operatively attached to an image processor, which processes the image frames acquired respectively by the camera. When a pedestrian is present in the viewing zone viewed by one of the cameras, the image processor attached to the one camera identifies in at least one of the image frames at least a portion of an image of the detected pedestrian.

Abstract: A clamp attachment for use with a lift truck for handling rail car bogies. The clamp attachment includes an upper frame that is attached to the carriage of the lift truck for upward and downward movement therewith. A lower frame is movably suspended from the upper frame by four chains. A pair of clamps assemblies are pivotally mounted on the lower frame and actuated by hydraulic cylinders to cause clamping and unclamping of the axles of the rail car bogie for the lifting and lowering of the rail car bogie. A plurality of hydraulic cylinders are arranged to move the lower frame and clamp devices therewith into any desired direction for the maneuvering of the rail car bogie.

Abstract: A stacking mast for being attached to a lift truck and for moving a load between a negative position and a positive position. The stacking mast includes an elongated first mast, the first mast including a lower end for being attached to the lift truck and including an upper end; an elongated second mast, the second mast including a lower end and an upper end; a floating carriage having a first securing structure for being slidably secured to the first mast and a second securing structure for being slidably secured to the second mast; a support carriage slidably attached to the second mast for supporting the load; and lift structure for moving the support carriage between a lower position and an upper position on the second mast and for moving the second mast between a lower position and an upper position on the first mast.

Abstract: An apparatus for clamping pipes and the like to the forks of a forklift truck. A flapper arm is pivotally attached to a frame member which straddles each fork of the truck. A clamp arm is pivotally attached to the opposite end of the flapper arm. A single piston extends between the frame member and clamp arm to cause the clamp arm to move between opened and closed positions.

Abstract: A fork attachment for a fork lift truck of the type having a vertically movable carriage. The fork assembly includes a pair of frames for being attached side-by-side to the carriage. Each frame includes a pair of side frame members having substantially U-shaped tops. An elongated shaft is adapted to extend between the side frame members of each frame and to rest in the U-shaped tops thereof. A plurality of spaced-apart fork members are slidably attached to each shaft. Outwardly extending pegs on each fork member coact with slots in an elongated bar extending the length of each shaft to control the spacing of the fork members relative to each other.

Abstract: The dust collecting bin of an air cleaner system of the type including a centrifugal-type separator for separating dust from air is coupled to the exhaust port of a pressurized air brake system so that any dust collected in the bin will be blown therefrom by any pressurized air exhausted from the brake system.

Abstract: An apparatus for use in reclaiming bulk material such as bean meal or the like from a pile of such material. A self-propelled wheeled vehicle is equipped with an elongated boom. An endless belt-like member is movably positioned along the length of the boom. A plurality of platelike blades are attached to the endless belt-like member for movement along the length of the boom so that when the boom is positioned against or adjacent a pile of bulk material, the platelike blades will scrape, rake or otherwise convey portions of the bulk material from the pile to an under-floor conveyor or the like.
