Abstract

A method and apparatus for supplying bulk material to an end user includes the step of providing a bulk material source that is at a location distant from the end user and a specially configured vessel and trailer apparatus for transporting the bulk material to the end user. The vessel is filled with bulk material at the bulk material source and then transported with a specially configured trailer. Alternatively, at source or destination, the vessel can remain as a temporary storage device, free-standing from the trailer. During transport between the bulk material source and the end user, the vessel is filled or partially filled with a selected bulk material. During transport, the vessel is in a generally horizontal position, supported by the trailer and a specially configured elevator. The vessel is unloaded from the trailer by moving the vessel longitudinally along the trailer and by transferring the vessel from a generally horizontal position upon the trailer to an elevated upright position.
