ABSTRACT:
A material handling machine including a power driven, steerable chassis which supports a vertical mast and a pivotally attached telescoping boom having a material carrier rack, including a device for securing material to the rack. The mast is supported on a base that is selectively movable in a transverse direction with respect to the chassis. The end of the telescoping boom carries a hydraulic orbiting motor that provides for selective rotation of the rack in either a clockwise or counter-clockwise direction. A pair of hydraulic cylinders, together with a universal joint, are attached to the rack and provide for pivoting or tilting of the rack about both the vertical and horizontal axes.
