  • Publication number: 20210395016
    Abstract: A weldment structure for reinforcing a boom of a material conveyor apparatus includes a pair of elongate rigid members having an overall length with cut ends, a set of cross members sharing an overall length with cut ends, the cross members fixed orthogonally to the elongate rigid members functioning to hold the rigid members apart and parallel and at the same edge alignment, and a set of cross support brackets fixed to the cross members and to the elongate rigid members, the cross support brackets each supporting at least a return roller bracket assembly and a pair of opposing belt guides.
    Type: Application

  • Patent number: 11021327
    Abstract: A telescopic material conveyer apparatus has a main boom assembly reinforced by a steel saddle frame connected to a turn table and a lift mechanism, an extension boom assembly adapted by two or more roller assemblies and connecting hardware to travel mechanically within the main boom assembly and to extend therefrom, one or more connected drive motors, a conveyer belt supported by frame architecture and a pulley and drive chain system, at least one hydraulic motor having operative connection to the turntable, lift mechanism and to a belt drive drum, at least one hydraulic valve connected inline in the hydraulic line controlling the belt drive motor, the valve electronically operable via input received from a load sensor integrated within or to the lift mechanism, a programmable load threshold determining open and close operation states of the valve and directing run and stop state operations of the conveyer belt.

  • Patent number: 9783368
    Abstract: A conveyor apparatus includes a conveyor belt supported by a first and a second roller assembly, a boom assembly housing the conveyor apparatus, the boom assembly including opposing side rails hosting roller assemblies at opposite ends thereof the side rails held parallel by a plurality of cross frame members. A drive motor connected to a chain sprocket and gear assembly fixed in turn to an axle of at least one of the roller assemblies drives the conveyor hydraulically.

  • Patent number: 9611098
    Abstract: A conveyor apparatus includes a conveyor belt supported by a first and a second roller assembly, a boom assembly housing the conveyor apparatus, the boom assembly including opposing side rails hosting roller assemblies at opposite ends thereof the side rails held parallel by a plurality of cross frame members. A drive motor connected to a chain sprocket and gear assembly fixed in turn to an axle of at least one of the roller assemblies drives the conveyor hydraulically. The conveyor apparatus further includes components protecting against wear from frictional contact with material conveyed, sudden static shock to an operator, and wherein the relatively non-conductive attributes of the component materials protect the operator from shock due to implied incidental contact with an external power source.
