A portable telescoping radial stacking conveyor for stacking bulk material such as aggregate, sand, coal, wood chips, grain, and similar materials has a fully extended length of 150 feet and a towing length of 80 feet or less. The unit may be converted from a highway transportable configuration to an operating configuration by one individual in approximately twenty minutes. Hydraulically operated radial drive wheels, elevating struts and stinger positioner can be manually controlled or controlled with a programmable logic controller (PLC) to position the discharge point at the desired location at the desired time. Segregation of stacked material according to particle size can be controlled by appropriately relocating the conveyor discharge point at frequent intervals so that the material is deposited in small piles that form layers of stockpiled material instead of the usual single large stockpile.
