Apparatus is provided consisting essentially of a feeder which receives material from trucks and a stacker which receives the materials off the feeder and transports the materials to a point where the materials are dropped into a stack. Provision is made for adjusting the height from which the materials are dropped and the stacker has adjustable wheel assemblies to permit the stacker to be moved transversely at the wheels so that the stacker swings in a horizontal arc and the stack can be thereby increased in size with respect to the area covered by the stack.
