There is disclosed a dry bulk hopper system that includes a generally frustoconical bottle and a base having a tapered wall that defines a cradle for holding the bottle. The bottle has locking tabs disposed at bottom end thereof that cooperate with engagement ledges to secure the bottle to the base when the bottle has been received into the base in a first orientation, but not in a second orientation. Extruded support columns are disposed inside an interior of the base to distribute loads created by material in the bottle when the system is raised by a forklift.

An expandable and collapsible grain bin is provided comprising at least two telescoping cylindrical sections adapted to interlock with one another when the grain bin is in an expanded position; a base member attached to the bottom most cylindrical section; and a bin cover for enclosing the grain bin, said bin cover adapted to be in a raised position when the grain bin is in the expanded position and in a lowered position when the grain bin is in a collapsed position.

An apparatus to support a proppant container includes a frame to receive and support the proppant container. The frame has a top surface that receives and positions the proppant container in an elevated position. The apparatus also includes a box guide assembly positioned on the top surface a box guide assembly connected to the top surface of the frame for defining a cradle section having four corners. The box guide assembly including a box guide positioned at each of the corners. Each box guide has a corner member extending upwardly from the top surface along a peripheral edge of the frame and a guide member extending adjacent the corner member. The guide member include an inclined face for aligning the proppant container in the cradle section. The box guide assembly guides the proppant container into the cradle section when loaded onto the frame in the elevated position.

In accordance with embodiments of the present disclosure, systems and methods for reconfiguring a vertical storage silo used to store proppant (or other dry material) so that the storage silo may be used in a desired orientation at a worksite are provided. The disclosed embodiments may include a vertical storage silo assembly used to selectively deliver material from one of two different outlet orientations. The silo assembly may offer two distinct orientations for an outlet chute relative to a transportation chassis used to transport and erect the vertical silo. The silo assembly may include a storage silo and a base for supporting the storage silo in a vertical orientation, the storage silo being removably coupled to the base. The storage silo may also be rotatable relative to the base to transition or reposition the outlet chute between a right-hand orientation and a left-hand orientation relative to the base.

A container is constructed to carry granular material from a quarry or source to the frac site. An open frame the size of a standard cargo container is constructed. An enclosed hopper is formed using flat sheet metal with bolted together perpendicular edges. The hopper is set within, and attached to, the frame. Top hatches provide for loading the hopper, and a lower sliding gate in a bottom opening provides for unloading the hopper. The bottom of the hopper is at an angle slightly above the angle of repose of the granular material carried therein.

Aspects of the present disclosure provide techniques and apparatus for multiple physical resource block (PRB) operations for narrowband (NB) systems, such as NB internet-of-things (IoT). In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE), which may be an NB-IoT device. The method generally includes performing a cell search based on one or more signals received in an anchor RB within a set of RBs available for narrowband communications with a base station (BS); determining a location of at least one additional RB available for the narrowband communications with the BS based on an indication received in the anchor RB; and performing narrowband communications with the BS using at least one of: the anchor RB or the at least one additional resource block.
