The present invention provides a telescopic conveyor (1) having at least two conveyor belts (10). Said belts are arranged one above the other and can be moved relative to one another in the longitudinal direction. Each conveyor belt (10) here has a frame (11), a circulatory belt (12) and a first deflecting roller (13) at a first end (A), and a second deflecting roller (14) at a second end (B), of the conveyor belt (10), wherein the second end (B) is a transfer end of the conveyor belt (10), and wherein a bridging device (2, 2) is provided between in each case two adjacent conveyor belts (10) located one above the other, and said device bridges, at least to some extent, the difference in height (H) between the two conveyor belts (10) arranged one above the other, it being necessary for said difference in height to be overcome at the transfer end. The bridging device (2) comprises a ramp (3, 3) with a slope (S) and also a first deflecting roller (4), which is arranged at the higher end of the ramp (3, 3), as well as a first holding-down device (5), which is arranged beneath the first deflecting roller (4), and also a second holding-down device (7) at the foot of the ramp (3, 3). The circulatory belt (12) of the respectively lower conveyor belt (10) is guided, from a conveying plane (E1) beneath the second holding-down device (7), over the ramp (3, 3) with the slope (S) and, from there, is deflected over the first deflecting roller (4) and guided back to the conveying plane (E1) beneath the first holding-down device (5). The slope (S) of the ramp (3, 3) continues in stepless fashion tangentially along the circulatory belt (12) of the conveyor belt (10) located above, said circulatory belt being guided over its second end-side deflecting roller (14).

Various example embodiments described herein relate to an item conveying apparatus. The item conveying apparatus can include a lift device suspended from a ceiling. Further, the item conveying apparatus can include a conveyor. The conveyor can be at least partially engaged with the lift device. The lift device can cause manipulation of a position of the conveyor. Further, the conveyor can include a conveyor frame and multiple conveyor segments. The multiple conveyor segments can define a conveying surface for conveying an item. In this aspect, in an example, at least one conveyor segment can be adapted to (a) extend outwards from the conveyor frame to move the conveyor into an operational position and (b) retract, inwards within the conveyor frame to move the conveyor into a parking position.

A boom conveyor includes a boom that carries a conveyor, a support structure for the boom, a rear pivot joint that connects a rear end of the boom to the support structure, and a pivot drive that controls pivoting movement of the boom about the rear pivot joint. The boom conveyor apparatus includes an operator platform and an attachment mechanism at a front end of the boom whereby the operator platform may be attached to the boom or detached therefrom. The attachment mechanism includes a leveling mechanism that is configured to apply a leveling adjustment to the operator platform.

The present disclosure is directed toward a two-conveyor mechanical conveyor belt system for granulated raw materials including a first conveyor that may be larger than a second conveyor. Both conveyors are configured to be mounted onto a mobile base such that the conveyor system has dimensions similar to a trailer for conventional cargo transport truck. The conveyor system may be used for loading and unloading granulated raw materials, preferably silica sand, into transporting trailers that are suitable for feedstock. The longer-length conveyor belt of the first conveyor defines a transporting belt. The second conveyor may be configured to be positioned between the first conveyor and a trailer, and includes a shorter-length belt that defines a connecting belt disposed between the first conveyor and the trailer. The configuration of the first and second conveyors provides an airtight or otherwise sealed connection between a raw materials-transporting trailer and a specialized container.

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. By automating the operation of the bootend, the need for human positioning control is reduced and the safety of operators is improved.
