Abstract: A belt tension-reducing device is provided, which includes a support member; a pliable central wheel assembly configured to engage a both downwardly and upwardly moving portions of the conveyor belt; first and second outboard roller assemblies positioned to engage the downwardly and upwardly moving portions, respectively. A second effective rolling radius of the pliable central wheel assembly at a contact point with the upwardly moving portion of the conveyor belt can be greater than a first effective rolling radius of the pliable central wheel assembly at a contact point with the downwardly moving portion of the conveyor belt to reduce stresses on the belt in a vertical shaft. The belt tension-reducing devices can be arranged in a stacked configuration within the vertical shaft.

Abstract: A belt conveyor includes a conveyor belt configured to move in a longitudinal direction. The conveyor belt has two large faces, and a number of support stations distributed longitudinally along the conveyor belt. The support stations are configured to support the conveyor belt by one of the large faces. At least one support station includes a drive motor configured to drive the conveyor belt in the longitudinal direction relative to the support stations.

Abstract: A linkage for moving material from a first end of a conveyor toward a second end of the conveyor includes a first link and a second link. The first link includes a first side edge and a first indicator. The second link includes a second side edge and a second indicator. The second link is coupled to the first link such that the first side edge of the first link overlaps with the second side edge of the second link. Elongation of the first link in the direction of movement causes the first indicator to move relative to the second indicator, and a position of the first indicator relative to the second indicator provides an indication of a wear condition of the first link. In some aspects, a first surface and/or a second surface of one of the links includes a wear indicator representing a surface wear condition.

Abstract: A material management system and method manages and tracks the progress of excavated material transferred through an excavation site by a conveyer system operating in cooperation with an in-pit crusher and conveyer (IPCC). The material management system distinguishes the material dispensed into the IPCC into identified material batches. To track the identified material batches, the material management system records data regarding the conveyer speed and the conveyer distance associated with the IPCC, as well as possible other data regarding the identified material batches. The material management system processes this to track the indentified material batches along the conveyer route.

Abstract: A tensioning mechanism for a conveyor system includes a support structure, a first carriage, a second carriage, and a brake mechanism. The first carriage is positioned proximate a first end of the support structure and is supported for movement relative to the support structure. The first carriage includes first rolls for receiving the belt such that movement of the first carriage modifies a tension in the belt. The second carriage is supported for movement relative to the support structure and includes second rolls and at least one return pulley. The second rolls are configured to support a portion of the belt extending between the first carriage and the second carriage. The brake mechanism is positioned proximate a second end of the support structure and includes a brake pulley and a brake selectively retarding rotation of the brake pulley. The brake pulley supports a portion of the belt extending between the brake mechanism and the return pulley.

Abstract: A conveyor sled assembly is utilized to supply proppant in support of oilfield hydraulic fracturing operations. The conveyor sled assembly includes precisely positioned components where tolerances between components are so small as to prevent significant spillage at component junction boundaries. This manner of fitting proppant pods onto the conveyor sled assembly increases predictability of which pods will discharge their proppant load first. This enhances reliability of the overall proppant delivery system.

Abstract: A conveyor includes an endless belt, a boot end supporting a portion of the endless belt, a support structure, and a bridge. The endless belt includes a first run and a second run, and the first run extends along a conveyor axis. The support structure includes an end spaced apart from the boot end, a plurality of frames, and a plurality of idler rolls. The frames are spaced apart from one another and aligned with one another in a direction parallel to the conveyor axis. The idler rolls support another portion of the endless belt. The bridge extends between the boot end and the end of the support structure. The bridge is movable in a direction parallel to the conveyor axis relative to at least one of the boot end and the support structure.
