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.

Disclosed a large-span bulk material conveying system, including a folding arm conveyor and a dike-striding elevation-type feeding conveying device. The folding arm conveyor is mainly composed of an undercarriage mounted on the ground of a stockyard, a tower body mounted on the undercarriage and provided with a gyration apparatus and a hopper, a balance arm provided with a balance trolley, a conveying arm provided with a portal frame I, a portal frame II and an unloading trolley, a tower top and other main components, wherein the balance arm, the conveying arm and the tower top are mounted on the tower body. The folding arm conveyor can rotate horizontally, and the conveying arm can be folded and retracted by controlling the wire rope by the windlass, so that the folding arm conveyor can be prevented from colliding with other devices or buildings during the rotation.

A measurement system used in conjunction with a conveyor includes a first sensor with a first transceiver and a second sensor with a second transceiver. The transceivers transmit a first light beam and a second light beam towards a movable portion of the conveyor. A control unit communicably coupled to the first sensor and the second sensor, wherein the control unit calculates a first distance between the first sensor and the movable portion based on the first sensor and a second distance between the second sensor and the movable portion based on the second sensor. The control unit determines a difference value between the first distance and the second distance; and stops the unloader in response to the difference value being above a predefined threshold value.

Automated control of a longwall stageloader bootend using a plurality of sensors. The sensors include lift sensors, side shift sensors, advance sensors, angle sensors, and conveyor belt sensors. Signals from the plurality of sensors are received by a controller and used to control the operation of the bootend. Controlling the operation of the bootend includes controlling, for example, one or more lift actuators, one or more side shift actuators, one or more advance actuators, and one or more belt actuators. These various actuators can be controlled to, for example, advance the bootend, level the bootend, or match the interfaces between the bootend and a stageloader or a conveyor structure.

Apparatuses, systems, and methods of manufacturing are described that provide a drop link and associated conveying system for item transport. An example conveying system includes a telescopic side guide that includes one or more sections and a plurality of drop links each supported by respective sections. Each drop link includes an extension mechanism that movably attaches the drop link to the section. Each extension mechanism allows translation of the drop link relative the respective section of the telescopic side guide between a retracted position and an extended position in which a portion of the drop link extends at least partially beyond an outer edge of the respective section of the telescopic side guide.
