Abstract: A trailer with loading and unloading capability. The trailer has side members, but is open at the rear, so that it may be backed into a position with the load between the side members. There are beams along each side member which can be lowered to receive crossbars passed under the load. Means are provided for lifting the beams and the load, supported by the crossbars, into a hauling position. The trailer has columns rising from the side members and brace members interconnecting the columns, which make the trailer strong even though it is open at the rear.
