A modular shipping apparatus comprising: a shipping container having a first track and a second track attached to the bottom interior; a base having a bottom portion with wheel assemblies that slide along the first and second track; a liftgate having a first liftgate track and a second liftgate track, wherein the first liftgate track and a second liftgate track are aligned with the first track and the second track attached to the bottom interior and is pivotally attached to the bottom interior of the shipping container, a first and second guide rail which extend a portion of the length of the sides and having a first and second removable wing portion removably attached to provide a removed position and a working position, wherein the working position of the first and second removable wing portions extends to at least the left side and right side, respectively, of the liftgate.

A container for holding product therein during shipment and being returned for reuse has a body, horizontal and vertical tracks attached to opposite sides of the body, and a plurality of dunnage supports extending between the tracks. Each dunnage support may be a unitary member or a multi-piece member including sliders or end members located at the ends of a tubular support. The dunnage supports support dunnage for supporting products for storage or shipment.

A cargo compartment configured to be installed in an aircraft and to accommodate a plurality of cargo receiving devices is provided. The cargo compartment surrounds a compartment interior space, and includes a floor structure arrangement having a floor surface facing the compartment interior space and configured to support cargo receiving devices loaded into the cargo compartment. The cargo compartment includes two opposite side walls extending laterally of the floor structure arrangement away from the floor surface, and the side walls include an entrance opening for access to the compartment interior space. The floor structure arrangement also includes an air cushion device having a plurality of cushion nozzles distributed in the floor surface, and the cushion nozzles are configured to blow air up from the floor surface in a direction perpendicular to the floor surface.

A container for holding product therein during shipment and being returned for reuse has guides containing generally L-shaped slotted tracks having horizontal and vertical portions. A plurality of dunnage supports extend between the tracks. Dunnage is suspended by the dunnage supports. The dunnage supports have narrowed portions engaged with the slotted tracks.

A secondary silo on a second portable frame is independently portable relative to a primary silo and a vertical conveyor on a first portable frame. The vertical conveyor conveys flowable proppant material from an intake hopper below the primary silo into either one of the silos. The silos have gravity discharge chutes that are gravity fed directly into a proppant blender unit. An unloader on wheels is self-propelled and steerable relative to the silos. The unloader can be lowered relative to the wheels to sit on the ground to allow vehicles to drive over the unloader for discharge. Intake hoppers of the unloader can be raised up against the vehicle to form a closed duct discharging from the vehicles into the unloader. A discharge of the unloader forms a closed passage with the intake hopper of the vertical conveyor.

A container for solar string transportation includes, on the inside of a solar-string storing section, a long-side side plate, and a short-side side plate, and has an upper opening of the solar-string storing section for loading and unloading, and a pair of solar-string lifting/lowering devices along the inner wall of the long-side side plate. The solar-string lifting/lowering device includes a driving gear section set on the bottom plate side, an endless chain member that revolves around a direction changing gear section set on the upper opening side, a plurality of solar-string placing devices fixed to the endless chain member and including, on the outer side thereof, a projecting section for placing the lower surface of an end edge of the solar string, and a shock absorbing member fixed to the back of the solar-string placing devices. The shock absorbing member holds the end edge upper surface of the solar string.

A liner wringing device (10) is disclosed for use with a container liner. The wringing device includes a housing (30) with an internal cavity which houses the mechanical components of the wringing device. The housing defines a central liner compression channel (40). The internal components include a bottom support plate (42) with a central opening 43 aligned along the central channel. The wringing device also includes a drive assembly (44) formed by four elastomeric rollers (45) positioned so that the peripheral contact surfaces (50) are aligned generally tangentially with the central channel. The four rollers are each mounted to a drive shaft/axle which includes bevel gears which are meshed so that all four rollers rotate in simultaneous, synchronic rotation through the actuation of a pneumatic air gear motor (57).

A container for holding product therein during shipment and being returned for reuse has a body, horizontal and vertical tracks attached to opposite sides of the body, and a plurality of dunnage supports extending between the tracks. Each dunnage support may be a unitary member or a multi-piece member including sliders or end members located at the ends of a tubular support. The dunnage supports support dunnage for supporting products for storage or shipment.

A container for holding product therein during shipment and being returned for reuse has a body, track assemblies attached to opposite sides of the body, and a plurality of support assemblies extending between the track assemblies. Outer members of the support assemblies have notches which enable the support assemblies to slide along the track assemblies to move parts supported by dunnage suspended by the support assemblies.

A container for holding product therein during shipment and being returned for reuse has a base and opposed sides, linear and non-linear tracks, and a plurality of dunnage supports extending between the tracks. At least one of the tracks on each side may be non-linear in the shape of a C or U or J. One type of dunnage support comprises end members and a tubular middle member, the end members being movable along the tracks. The dunnage supports support dunnage, such as pouches.
