Abstract: A self-propelled screening apparatus (1) having a chassis (11); a pair of endless tracks (12) supporting the chassis (11); a superstructure (13) rotatably mounted on the chassis (11); a prime mover (19) provided in or on the superstructure (13) and arranged to provide motive power to operate the endless tracks (12) and where the prime mover (19) is rotatable with the superstructure (13); and a screen box (16) mounted on the superstructure (13), also for rotation therewith. The screen box (16) has an input (17) for receiving a supply of bulk material, at least one screen deck for screening the bulk material, and an output for discharging screened material. The prime mover (19) and the screen box (16) are arranged on opposite sides of the rotational axis of the superstructure (13), to provide a stable weight distribution.

Abstract: This disclosure is concerned with the generation of power by a wind-driven power generator, in which the generator is transported from a public highway to a required site on a tracked vehicle having a loading platform on which the generator is loaded, and then is erected on site to convert prevailing wind into mechanical power, and electrical power.

Abstract: A mobile material handling apparatus (10) having a frame (11), an input arrangement (13) for receiving a bulk supply of raw material to be handled, a screen box (16) or other material processing device, a conveyor (17) to transfer the material from the input arrangement (13) to the material processing device (16), one or more discharge conveyors (14, 15) to discharge the processed material, and a wheel set (12) supporting the frame (11) to render the apparatus mobile e.g. to be transported along the public highway via a fifth wheel coupling or low loader. In order to provide the apparatus with a capability of being manoeuvred on site, a set of endless tracks (20) is mounted on the apparatus frame (11) and is adjustable between an inoperative condition out of contact with the ground, and an operative ground-engaging position when it is required to manoeuvre the apparatus on site.

Abstract: A combination of a tractor unit (10) and a wheeled trailer combination, preferably a mobile screening plant (100), in which the tractor unit (10) has endless tracks (11) to render the combination highly maneuverable, and carries an upwardly and downwardly adjustable “fifth wheel coupling” (13) which pivotally connects the forward end (115) of the screening plant (100), the latter having a wheelset (118) at its rear end, and in which the screening plant (100) has an input hopper (114), an elevator (112) for conveying material to be screened from the hopper to a screen box (117), and one or more discharge conveyors (121, 123) for discharging screened material to form one or more stockpiles of screened material.

Abstract: A material processing plant e.g. a crusher or shredder (2) adapted to be suspended between a first wheeled unit (3) and a second wheeled unit (4) during transport, in which the first and second units have respective couplings, and in which the plant comprises: a plant frame; and front coupling and a rear coupling provided at the front and rear of the plant frame respectively; an arrangement of the front and rear couplings such that when the front coupling and the rear coupling of the plant frame are connected to the respective couplings of the first and second wheeled units, the plant (2) is suspended between the first and second units; and a lifting means (37) connected to one or both of the wheeled units (3,4), or to the plant frame, and operable to lift the plant for connecting the couplings of the plant frame to the respective couplings of the first and second wheeled units.

Abstract: A self-propelled material-processing apparatus (10) comprises a chassis (12), an engine (13) mounted on the chassis near the forward end thereof, and endless tracks (14) permanently supporting the chassis (12) and power-operated by the engine (13). A supply conveyor (18) has a material-receiving end (15) which projects forwardly of the forward end of the chassis (12) and an opposing upper discharge end (21). A material processing device (11), e.g., a screen box, is mounted directly or indirectly on the chassis (12) generally above the rear end of the chassis (12). The material processing device is arranged to receive material from the discharge end (21) and is configured for movement between an operative position and a transport position. The weight of the apparatus, when in the operative position, is generally balanced by the engine (13) and forward end (15) of the conveyor (18) at the forward end of the chassis and the screen (11) and discharge conveyor (121) at the rear of the chassis.

Abstract: A mobile screening apparatus includes a wheel-supported main frame and a hopper mounted at or near to one end of the main frame. An elevator mounted on the frame feeds material received from the hopper to a screening device which screens the material into different size ranges. Discharge conveyors discharge different size ranges of the screened material to respective discharge positions. A tractor unit is releasably coupled with a towing coupling provided at one end of the main frame. The tractor unit is operative to move the apparatus over the ground while screening operations take place so that traveling deposits of screened material can be formed. A power plant mounted on the frame is arranged to drive the screening device, the elevator, and the discharge conveyors.

Abstract: A self-propelled screening apparatus (10) having a support frame (11), endless crawler tracks (15) supporting the frame (11), a hopper (13) and screen or screens (12) mounted on the support frame (11), and a discharge conveyor (14) mounted on the frame (11) and operable to discharge at least one separated portion of screened material (received from the screen) along a required deposition zone while the apparatus is moving.

Abstract: A conveyor assembly comprises a main conveyor and a boom conveyor. A mounting is pivotally connected at the discharge end of said main conveyor for movement about a transverse axis relative to said main conveyor, said mounting having a rotatable support on which the boom conveyor is mounted for pivotal movement laterally. A linkage retains said mounting in a horizontal position extended outwardly beyond said discharge end with said rotatable support upright. The support has an attachment device at its upper end providing for pivotal connection about a transverse axis of said boom conveyor for movement thereof in a vertical plane, the boom conveyor being supported by a length-adjustable tie from said mounting. The linkage comprises a series of interconnected pivotal links between said mounting and said main conveyor to provide for synchronized adjustment of the mounting to maintain the support upright on alteration of the inclination of said main conveyor.
