Abstract: Telescopic conveyor belt, with a base conveyor section, a telescopic conveyor section on the base conveyor section and which can be extended and retracted telescopically, in and counter to a direction of extension, an endlessly circulating conveyor belt forming a conveyor surface and which, with its carrying run, is led along an upper surface of the base conveyor section and of the telescopic conveyor section, a base guide trough closed on the underside and arranged between the conveyor belt and the base conveyor section, has a carrying area for accommodating the conveyor belt and has raised guide areas following on laterally from the carrying area, and a telescopic guide trough closed on the underside and arranged between the conveyor belt and the telescopic conveyor section and has a carrying area for accommodating the conveyor belt and has raised guide areas following on laterally from the carrying area.

Abstract: A conveyor assembly (26) includes a first frame (50) supporting a first conveyor (28) for feeding material in a first conveying direction. The conveyor assembly (26) also includes a second frame (60) supporting a second conveyor (30) for feeding material in a second conveying direction parallel to the first conveying direction. The second frame (60) is movable with respect to the first frame (50) along the second conveying direction between a retracted position and an extended position. A side shield (70) is connected to a side of the second frame (60) and shields the second conveyor (30) laterally. An elongate, flexible seal (94) is mounted to the side shield (70), the flexible seal (94) bridging a gap between the side shield (70) and the second frame (60).

Abstract: A feed auger assembly which conveys particular material to an implement includes a first auger housing with a first auger flight rotatable therein, a second auger housing concentrically receiving the first auger housing therein so as to define an annular space therebetween, and a second auger flight rotatable within the annular space. The discharge end of the first auger housing is arranged to discharge into the annular space between the intermediate end and the outlet end of the second auger housing as the first auger housing is longitudinally slidable relative to the second auger housing in the longitudinal direction. The distance between the inlet end of first auger housing and the outlet end of the second auger housing is thus adjustable during a conveying operation of the augers being rotated within the respective housings.

Abstract: In a movable conveyor belt storage installation including a belt storage means (4), conveyor belt support structures (29) following the belt storage means (4), and a movable takeover car (7) including a deflection means (43) for the conveyor belt and a takeup chute (8) for taking over excavated material, the belt storage means (4) is comprised of at least two segments (13, 20, 22, 26) which are connected with one another so as to be pivotable about an axis extending transversely to the belt running direction and passing through the plane of the floor (31), wherein at least a portion of the support structures (29) are capable of being carried along in or on the takeover car (7).

Abstract: In a transfer conveyer wherein a pair of guide rails respectively provided with guide surfaces for guiding both side surfaces of a transferred article in a transfer direction are extended in the transfer direction and wherein flexible endless belts are provided for supporting lower surfaces at both sides of the transferred article, whose both side surfaces are guided on the guide surfaces, to transfer the transferred article in the transfer direction, a stretching mechanism is provided on one end portion of each guide rail to be stretchable in the transfer direction, a stretchable guide surface for defining a flat surface continuous and even with the guide surface regardless of any stretched position is formed at a facing surface of each stretching mechanism, and plural pulleys for circulatably supporting a part of the endless belt are provided on the facing surface of the stretching mechanism.

Abstract: Powered and steerable telescoping conveyors. The telescoping conveyors have an infeed section and a discharge section. The discharge section can be telescoped beneath the infeed section in a retracted position. In an extended position, containers can be conveyed over first and second conveying structures that are located on the infeed and discharge sections, respectfully. The conveying structures can include wheels, rollers, or belts. A power module can move the discharge section between the extended and retracted positions. The power module can be located at various positions along the conveyor, including at a discharge end of the discharge section. A steering assembly can be provided to orient the discharge section with respect to the infeed section. The steering assembly can include two wheels, each wheel having its own independent wheel-steering axis. A power module can be associated with each of the independent wheels.

Abstract: An extensible conveyor system that uses idler shuttles that include a base with sides, a front section and a rear section, and a mechanism that allows the frame to be moved along a support, these mechanisms may be wheels, slides, bearings, bushings, or other carriers, the sides of the base being generally symmetrical. The idler shuttles also include an idler support frame that extends from the base at an angle, the angle may be perpendicular or any other angle, the idler support frame being mounted between the front portion and the rear portion, the front portion of the base being adapted for nesting within the rear portion of the base, so that several of the support frames can be nested against one another to reduce the overall space taken up by the shuttles when the conveyor system is in a retracted position.

Abstract: A boom conveyor including a cantilevered conveyor section having an operator's platform at its outer free end is disclosed. The conveyor section is mounted so that in use the outer free end is movable in a vertical plane between predetermined limits. A scissor support is disposed at or adjacent the outer free end and is passively extended by the raising of the free end of the conveyor to provide continual support to the platform. A release valve enables retraction of the support when the free end is lowered.
