System, method, and device for fabricating a capsule are provided. A gripping apparatus includes a rotary actuator and a rotary linkage disposed about a periphery of the rotary actuator. A plurality of intermediate linkages is coupled to the rotary linkage. Each intermediate linkage includes an input end portion coupled to the rotary linkage, an output end portion disposed below the input end portion, and a jaw disposed on the output end portion. The gripping apparatus includes a plurality of compliance linkages. Each compliance linkage includes a first end portion coupled to either the output end portion or the jaw of a respective intermediate linkage, and a second end portion substantially orthogonal to the respective intermediate linkage.

A storage container system includes a storage container having a frustoconical roof defining a central opening and a lid assembly mounted to the roof of the storage container. The lid assembly includes a rail guide member mounted to the roof of the storage container and oriented such that a center longitudinal axis of the rail guide member has a same pitch as the roof and a lid rotatably coupled to the rail guide member and configured to slide along the rail guide member between open and closed positions over the opening, where when the lid is in an open position, an upper surface of the lid has a same pitch as the roof.

Embodiments of methods and systems of transferring proppant for fracking to reduce risk of production and release of silica dust at a well site are provided. An embodiment of a method can include positioning a plurality of containers each having proppant for fracking contained therein onto a conveyor at a well site, downwardly discharging proppant from each respective container of the plurality of containers, funneling proppant from the one or more outlets of each of the plurality of containers through a plurality of conveyor hoppers, receiving proppant onto the conveyor belt, conveying proppant on the conveyor to a chute, and depositing the proppant into the chute for use in a blender or other location at the well site.

The present invention discloses a container, comprising a container body and a lid, the container body comprises a base and side plates, the lid is provided with a first hanging-against structure, the side plate is provided with a second hanging-against structure cooperating with the first hanging-against structure, the first hanging-against structure and the second hanging-against structure are separatable to achieve hanging-against and removal of the lid, the lid is slidable above the container body whereby the first hanging-against structure and the second hanging-against structure are brought close to or away from each other, wherein the first hanging-against structure is slidable along the lid for a certain distance so that the position of the center of gravity of the lid changes relative to the first hanging-against structure. The present invention can realize the multi-directional hanging function of the lid and the container, with novel and reliable structure, simple and convenient operation, solid and durable.

A container-securing device is provided. A main body of the container-securing device is detachably/attachably supported on a cargo bed yet movement of the main body is restricted in any direction within the horizontal plane. The container-securing device 1 includes a socket 3 which is fixed onto the cargo bed; and a main body 2 which is fixed into the socket 3 to fix a container: The main body 2 has its lower region formed with projections 22b extending horizontally; and the socket 3 has a storage space 31 to store the projections 22b, a first restrictor 32 around the storage space 31 which allows rotation of the projections 22b within a horizontal plane but restricts other movement thereof in any direction within the horizontal plane, an opening 33 which communicates with the storage space 31 and allows the projections 22b to be inserted through, and a second restrictor 34 around the opening 33 which restricts movement of the projections 22b in the vertical direction.

A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.

A transportable container apparatus includes an elongate container having a central axis and a base attached to a bottom end of the container. The container and base are substantially symmetrical about the central axis and the container is oriented substantially vertically with the base resting on a ground surface when in a working position. The container having an upper container section with upper walls substantially parallel to the central axis and a lower container section with lower walls substantially parallel to the central axis. The upper container section includes a sloping hopper at a bottom thereof to direct granular material into the lower container section. A floor of the container is sloped toward an outlet port defined in a ported wall of the lower container section such that granular material stored in the container slides down the floor to the outlet port.
