A belt conveyor having a pair of side frames between which a belt is moved for conveying items includes a pair of idler rollers about which the belt is disposed for conveying items there between, a tension roller that is biased into engagement with the belt, and a driven roller operative to drive the belt about the idler and tension rollers. The tension and driven rollers are mounted between the side frames and are disposed lower than the idler rollers, with the tension roller mounted by a tensioner mount configured to impart a biasing force to the tension roller against the belt.

A belt conveyor system for creating an overland material transport assembly on a ground surface comprises a frame configured for transportation over the ground surface, a plurality of pivotally connected conveyor belt support sections, a head pulley assembly mounted to the first end of the frame, a tail pulley assembly mounted to one of the conveyor belt support sections, and a conveyor belt. The frame includes first and second elongate rails, each of which have a first support surface and a second support surface spaced from the first support surface. The plurality of pivotally connected conveyor belt support sections are supportable on the frame in a transport configuration wherein the plurality of support sections are accordion-folded relative to one another and are generally perpendicular to the first and second elongate rails. The plurality of pivotally connected conveyor belt support sections are movable to a material transport configuration wherein the plurality of support sections are unfolded to be generally parallel to the first and second rails. The belt conveyor is carried by the head pulley assembly, the plurality of conveyor belt support sections and the tail pulley assembly.

The present invention consists of a mechanism of two conveyor belts with different lengths, one larger and one smaller, which are mounted on a mobile base with dimensions similar to a conventional cargo transport truck's trailer; to be used in the loading and unloading of granulated raw materials, preferably silica sand, in transporting trailers of said feedstock, and in which the belt with a greater length is the transporting belt and the one with the shorter length acts as a connecting belt between the longer one and a trailer. This invention has been created in response to the need of hermetically connecting a raw materials-transporting trailer to a container, having specific modifications that allow the clean and waste-free movement of raw materials.

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.
