ABSTRACT:
A roller attachment for dump trucks has one or more road rollers mounted on a shaft which in turn is carried on the end of a pair of hydraulic piston and cylinder assemblies mounted on a beam positioned transversely of the truck and detachably secured to the frame thereof. Actuation of the hydraulic piston and cylinder assemblies from the hydraulic system of the dump truck moves the roller toward and away from a road surface so that when the roller is engaged on the road surface and the truck is moved forwardly and backwardly the roller will compact materials therebeneath.
