ABSTRACT:
An apparatus and method for transporting and unloading a container (10, 10A) carrying particulate lading which is removably mounted on a tiltable support frame (76, 76A) pivotally mounted on a highway trailer (54, 54A). At the unloading site, a portable throttle valve assembly (108, 108A) and flexible connecting hose (166, 166A) are connected to the container (10, 10A) and the container (10, 10A) is tilted by the support frame (76, 76A) to an angle above the angle of repose of the lading for gravity unloading of the lading from the container (10, 10A) in to a trailer mounted rotary valve (148, 148A) which forms an air lock over a subjacent pneumatic hopper structure (144, 144A) for pneumatic conveyance of the lading to a storage facility. The height of the discharge opening (46, 46A) in the container (10, 10A) above the rotary valve (148, 148A) during unloading is sufficient to provide a continuous gravity flow of lading from the container (10, 10A) to the rotary valve (148, 148A) at an angle at least generally similar to the angle of repose of the lading being unloaded.
