Abstract

Apparatus and methods are described for efficient and precise placement of discrete quantities of materials adjacent to the apparatus. The apparatus and methods are particularly adapted for being coupled to a dump truck, receiving material contained in the bed of the dump truck into a hopper, metering the material in the hopper by a receiving conveyor and transferring the metered material from the receiving conveyor to the side of the apparatus by a cross conveyor positioned perpendicularly to the receiving conveyor. A telescoping boom conveyor having a material director transfers the metered material from an end of the cross conveyor and places the metered material adjacent to the apparatus. Attached at the other end of the cross conveyor is a material positioning attachment for positioning the precisely placed material into a level grade or a road curb.
