A bulk material shipping container unloader having an expandable supporter, a pallet receiver supported by the extendable supporter, and a material director supported by the pallet receiver.

A metering system includes a frame, first and second gates, and an actuator. The frame defines a chute configured to receive a supply of fasteners and maintain the fasteners in a line. The first and second gates are each mounted to the frame and movable to advance into the chute and retract away from the chute. The actuator is mechanically coupled to the first gate and configured to advance and retract the first gate relative to the chute. The second gate is configured to move based on the movement of the first gate so that as the first gate advances into the chute to block movement of the fasteners in the chute the second gate retracts, and as the first gate retracts away from the chute the second gate advances into the chute to block the movement of the fasteners in the chute.

In an article processing apparatus (1), a plurality of hoppers (12) are disposed in a circular shape and each of the plurality of hoppers (12) causes an article (100) received from an upstream side to temporarily stay and then discharges the article (100) toward a discharge opening (20) on a downstream side. Each of the hoppers (12) includes: a body portion (12A); a slide portion (12B) provided on a downstream side of the body portion (12A), and having a slide surface (120) extending continuously from the body portion (12A); and a gate (12C) provided on the body portion (12A) to switch between a first state where the gate (12C) causes the article (100) to stay in the body portion (12A) and a second state where the gate (12C) releases the staying of the article (100) to cause the article (100) to slide down from the body portion (12A). The slide portion (12B) has a length (L) or an angle (A) with respect to a horizontal direction (H) of a path along which the article (100) slides down the slide surface (120), takes off from a downstream end portion (120E) of the slide portion (12B), freely falls in a space (S) where the slide surface (120) does not exist, and then reaches the discharge opening (20), in the second state.

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 bulk material shipping container unloader having an expandable supporter, a pallet receiver supported by the extendable supporter, and a material director supported by the pallet receiver.

In accordance with presently disclosed embodiments, systems and methods for handling bulk material in a manner that reduces dust, noise, and emissions are provided. The presently disclosed techniques use portable containers to transfer bulk material from a transportation unit to a blender inlet. The containers may be carried to the location on the transportation unit, where a hoisting mechanism is used to remove the container from the transportation unit and place it in a desired location. When bulk material is needed at the blender inlet, the hoisting mechanism may position the container of bulk material onto an elevated support structure. Once on the support structure, the container may be opened to release bulk material to a gravity feed outlet, which routes the bulk material from the container directly into the blender inlet. The disclosed containerized bulk material transfer system and method allows for reduced dust, noise, and emissions on location.

The present invention is directed to a cover assemblies for use with containers such as large dumpsters or roll-off containers. The cover assembly generally includes a cover portion, a frame portion, and one or more mounting arms. The cover is coupled to the frame, and the frame is movable with respect to the mounting arm from a first position to a second position, wherein the first position comprises a closed position and wherein the second position comprises an open position.

An air cargo container has a tubular head rail extending across the front opening of the container. Sliders are provided in or on the head rail. A curtain door has sheet of flexible material and flexible straps attached to the sheet. The straps are attached to the sliders. The curtain door may be opened and closed via the sliders sliding along the head rail.

A bulk material shipping container including a pallet, a compartment mounted on the pallet, a material unloading assembly, and a material loading assembly.
