The present invention discloses an intermediate bulk container and a valve opening/closing device therefor. The container comprises a base, side plates, and a valve installed at the bottom of the container. The valve opening/closing device comprises a handle, a motion-transferring device, a valve opening/closing mechanism and a clutch device. The handle is installed on the side plate and is connected to the motion-transferring device. The motion-transferring device is used to transfer the actions acting on the handle to the valve opening/closing mechanism so as to achieve opening/closing of the valve. The clutch device is used to engage the motion-transferring device with the valve opening/closing mechanism or disengage the motion-transferring device from the valve opening/closing mechanism. According to the valve opening/closing device of the present invention, the operating handle is provided at appropriate position of the side plate of the container, thereby avoiding actions such as bending over or squatting on the ground while opening/closing the valve, thus it is convenient for use and can prevent the valve from being opened by mistake.

A system for selectively covering a container with a tarp. The system includes a roller and a tarp connected to the roller. A motor is connected to an output member, and the output member is releasably engaged with the roller. Actuation of the motor when the output member and the roller are engaged causes movement of the roller relative to the tarp. A crank is releasably connected with the roller, wherein one of the crank and the roller is connected to a coupler and the other of the crank and the roller is connected to a joint. When the output member and the roller are disengaged and the crank is connected with the roller, rotation of the crank causes movement of the roller relative to the tarp.

A cargo container is modified to carry a fracing proppant such as sand from a quarry or source to the frac site. Openings are cut in the top and bottom of a cargo container and hydraulically operated sliding doors are placed there under. A hopper module with the walls being inclined to approximately the angle of repose for the proppant is installed inside the cargo container. The hopper module is sealed inside the cargo container so that a proppant enters through the top opening at the quarry and flows out through the bottom opening at the fracing site.

In accordance with presently disclosed embodiments, a collapsible and optionally stackable storage container for bulk material is provided. The disclosed storage container includes a collapsible frame defined by a rigid upper support structure, a rigid lower support structure and a support member coupled at one end to the upper support structure and coupled at another end to the lower support structure. An actuator is also provided which is coupled to the support member at one end. The disclosed storage container further includes a storage sack having an upper portion coupled to the upper support structure and a lower portion coupled to the lower support structure. The lower portion of the storage sack is generally taper-shaped and may be equipped with a discharge opening that enables release of the bulk material onto a conveyor, which may be employed when the collapsible storage container is integrated into a bulk storage system.

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.

A container (10) comprises a base (41), side panels (40) and a cover (30). The side panels (40) are connected to the base (41). The cover (30) is locked onto the tops of the side panels (40) through a locking device. The locking device comprises automatic locks (50) and manual locks (60). The automatic locks (50) are arranged on two opposite sides of the cover (30), and the manual locks (60) are arranged on the other two sides of the cover. The automatic locks (50) and the manual locks (60) are both adopted on the cover (30) and used in cooperation with a tilting-pre-vention device, thus the container (10) has the tilting-pre-vention effect, the stacking and supporting effect, and the locking and unlocking guiding and return guiding effect. The locking strength is increased, and the convenience in locking operation and unlocking operation is improved.
