Abstract
Abstract The present invention relates to an improved trailer for transporting and dispensing pulverulent material having at least one bin for storing said material and a source of compressed air for unloading said bin and conveying said material mounted thereon. The trailer includes a frame having a load support rail extending along each side thereof, and having a wheel assembly and means for connecting the frame to a motor vehicle attached to opposite ends thereof. A material conveying line is integrally incorporated in one or both of the load support rails thereby greatly increasing the strength of the frame and obviating the need for supporting the material conveying lines above or below the frame.
