A haulage arrangement has a frame configured for operative attachment to a suitable tractor, and defining a tray for operatively receiving particulate material therein. The tray comprises two side walls separated by a loadbearing lower section with a headwall at a head end of the tray and slidably arranged in-between the side walls. Also included is an urger at the head end configured to operatively urge the headwall to slide across the lower section. Arrangement further includes an elastically flexible floor slidably arranged on the lower section and fast at a first end with the headwall, as well as a retractor arranged at an ejection end of the tray and configured to continuously retract a second end of the floor underneath the lower section whilst the headwall is urged. The retractor is further configured to agitate the floor during retraction to counteract adhesion of particulate material ejected from the tray.

A container assembly for flowable materials, the container assembly comprising: a reusable outer supporting container; and a disposable inner plastic liner; wherein the reusable outer supporting container comprises an outlet pipe comprising a first outlet pipe section connected to the reusable outer supporting container and a second outlet pipe section releasably connectable to the first outlet pipe section, wherein the second outlet pipe section comprises a valve for selectively closing off the second outlet pipe section, and wherein at least one of the first outlet pipe section and the second outlet pipe section comprises an annular recess; and wherein the disposable inner plastic liner comprises a tubular outlet portion, wherein the tubular outlet portion comprises an outer flange configured to be captured between the first outlet pipe section and the second outlet pipe section, and further wherein the outer flange of the tubular outlet portion comprises an annular protrusion configured to be received in the annular recess when the outer flange is captured between the first outlet pipe section and the second outlet pipe section.

Aspects of the present disclosure provide an automatic self-unloading material handling system that replace conventional material handling unloading systems. The automatic material handling unloading comprising a container with a roller assembly floor; a moveable bulkhead; a control enclosure; gear drive guide track assemblies; gear drive assemblies; a power track; a battery; and a power collector. Particularly, an Automatic self-unloading material handling system constructed as set out herein, can be configured and programmed to satisfy user-specified dimensions and load ratings, dynamic loading, ect, while provide a material handling unloading system that is lighter than what is realized in conventional unloading systems at comparable dimensions and load ratings. The automatic self-unloading material handling system is programmable with automated features to unload cargo from a container autonomously.

The container includes a lower wall and an erect side wall limiting an upper opening of a housing for accommodating a flexible pouch containing a fluid; containment elements including a containment wall, the gap between its peripheral edge and the side wall being limited; the containment wall adapted to be applied against the pouch and held fixed in this position by holding elements arranged in the container and borne by the containment elements by a structural and functional combination, and being movable between an inactive retracted state and an active expanded state, in which a distal end part is either moved away from the side wall or applied there against without any chance of sliding; and adapted to be applied at any desired location of a zone of the side wall such that the containment wall can be applied and held against the pouch regardless of how full the latter is.

The present invention relates to a tank piston with an improved seal having a cap, a body attached to the periphery of the cap, a circumferential channel adjacent to the periphery of the cap and an annular seal held within the channel by an annular sheet. In one aspect of the invention the annular sheet secures the seal within the channel and is attached to the piston by a ring proximate to the periphery of the cap and a ring proximate to the back side of the circumferential channel. In another aspect of the invention the annular sheet is made from a friction reducing material and enables the piston to more easily move within the tank and subsequently extends the lifespan of the seal. Additionally, the annular sheet is fitted to the seal and attached above the front sidewall of the channel.

The invention relates to a mobile storage container for bulk material in the form of a container unit which is dimensioned such that it can be transported on public roads and in public areas without requiring special permits for said transport. The container unit has a container with sidewalls, an underfloor, and an intermediate bottom arranged above the underfloor. The container has a stiffness that allows for the container to be set up even in the filled state on any essentially level ground without pillar mounting and without a foundation. A discharge device for the bulk material and a cross conveyor are integrated into the container, and a vertical conveyor connected to the discharge device is integrated into the container unit. By means of the discharge device, the bulk material is dispensed at a discharge height from the container unit and transferred to the vertical conveyor. From the vertical conveyor, the bulk material is dispensed at a drop height, which is higher than the discharge height.
