Swing Further. Pile Smarter.
Radial stacking conveyors offer a versatile, cost‑effective solution for medium‑ to high‑volume aggregate production—sand, gravel, crushed stone, and more. Mounted on a pivoting axle with a wheeled or tracked undercarriage, they rotate around a fixed feed point, allowing a single conveyor to build large, desegregated stockpiles with minimal loader re‑handling.
Engineered with reinforced truss frames, adjustable discharge heights, and variable belt speeds, radial stackers maximize yard density while minimizing material degradation and fines segregation. Their mobility simplifies repositioning as stockpile zones fill, and their modular design supports easy integration into portable or stationary plants. Ideal for quarry operations, sand plants, and contractor yards, radial stackers deliver reliable, low‑maintenance performance—helping you stack more, move less, and improve your bottom line.

Frequently Asked Questions
-
A radial stacker rotates horizontally around a central pivot point, allowing a single unit to distribute material across a wide arc and form large, uniform stockpiles without repositioning.
In contrast, a fixed stacker discharges material at a stationary point, creating cone or ridge piles that quickly reach maximum height and require additional space or loader rehandling.
On the same footprint, radial stackers can increase usable stockpile capacity by 30% to 50%, making them particularly valuable for operations where land is limited or expensive.
-
While radial stackers typically have a higher upfront cost due to additional components such as slewing drives and hydraulic systems, their lifetime operating cost is often lower. By automating material placement and reducing dependency on wheel loaders and dozers, radial stackers lower fuel consumption, labor requirements, and equipment wear. Many operators find that savings in fuel, labor, and maintenance offset the higher initial investment within 12 to 24 months of continuous operation, depending on throughput volume and material type.
-
The space-saving advantage of radial stackers comes from their ability to build higher and wider stockpiles on the same footprint. Because the conveyor rotates and layers material in a controlled pattern, the resulting pile is denser and more uniform than the steep cone pile from a fixed stacker. This translates to 30–50% more usable storage volume without expanding your yard—equivalent to storing 1.5 truckloads in the space previously used for 1 truckload.
-
Yes, radial stackers are highly versatile. They can handle a wide range of bulk materials including aggregates (sand, gravel, crushed stone), ores, coal, overburden, biomass, C&D debris, cement, grain, and recycled materials such as asphalt, concrete, and metals. For abrasive materials, abrasion‑resistant belting and reinforced truss frames are recommended; for sticky or high‑moisture materials, belt cleaners and reduced belt speeds help prevent carryback and blockages.
-
Unlike portable conveyors that must be moved frequently as the pile grows, radial stackers only need repositioning after a stockpile zone is fully completed. The radial rotation allows a single unit to build an entire pile without moving the pivot point. Once the pile reaches the desired size, the stacker can be towed or tracked to a new location to start a new stockpile—typically once every few days or weeks depending on throughput.
-
Regular maintenance is essential for reliable operation. Key tasks include: inspecting and tensioning the conveyor belt, greasing pivot and idler bearings, checking gearbox oil levels, monitoring slew drive wear, cleaning pulley areas to prevent material buildup, and verifying hydraulic hoses and fittings for leaks or wear. Keeping a parts inventory for belts, bearings, and drive components minimizes downtime when replacements are needed.
-
Absolutely. Radial stackers are designed with modular configurations that support easy integration into both portable and stationary plants. They can be fed from existing crushers, screens, hoppers, or overland conveyors. For operations looking to scale up, adding a radial stacker requires minimal civil work—typically just a stable foundation or compacted pad for the pivot point—making it a cost‑effective upgrade compared to reconfiguring an entire material handling layout.
