Super Portable® Radial Stacker

Back to Mobile Stacking Systems

The Super Portable® system's Radial Stacker Conveyor uses crawler tracks with Variable Frequency Drive propulsion to slew in an arc around a hitch pin on the Horizontal Conveyor, or to be pulled behind the Horizontal Conveyor.

It is also equipped with an operator's cabin. As the Super Portable® name implies, it is larger than a conventional radial stacker: 180'-190' compared to about 120'.

The basic function of all Radial Stacker Conveyors is to lay down a row of agglomerated ore at a uniform height and width on the leach pad. This is accomplished as the stacker moves in a slow slewing motion (alternating horizontally from side to side) while ore flows. Each stacker is equipped with a hydraulically operated 20' long extension or "stinger" (which is up to 30' long on Super Portable radial stackers).

During operation, the operator retracts the stinger conveyor back as the Stacker conveyor completes each sweep to the right or the left. When the last row of ore is stacked and the stinger is fully retracted, the Stacker / Horizontal Conveyor must be moved back or retreated to a new position and the stinger fully extended. Because the stacker pivots at its tail end, the rows of ore are stacked in an arc.

Because of the Super Portable's additional size and weight, TNT performs advanced computer-aided structural modeling and fatigue analysis, and uses state-of-the-art propulsion and control technology.
