Stackers are bulk stockpiling machines that are used to stack material in stockyards in different shapes according to specific requirements.
TAKRAF supplies a complete range of stackers for the heaping of circular or longitudinal piles, as well as for the homogenizing and blending of bulk material. The structure of the stockpile is dependent on the specific requirements of the various bulk processes, ie. chevron, windrow, strata or cone shell.
Our machines are all specifically designed to our client's requirements and incorporate various solutions according to their specific application. Our typical machines cover the following flow rates and sizes:
- Capacity: 300 t/h to 20,000 t/h
- Outreach: 15 m to 60 m
- Rail gauge: 4 m to 12 m
We have supplied a variety of different machines across numerous commodities around the world, each with their own specific configuration that's fit for purpose. Depending on specific requirements, we're able to supply machines with a boom length of up to 200 m.
Our machines generally boast a typical design structure and include a hydraulic lift system and counterweight at the rear end of the boom, although we have built machines to handle ore which boast an L-frame, a rope winch and a horizontal swivel boom. We offer machines with and without slewing ability.
A particularly intricate and special design that we are also able to provide is what is known as a "radial stacker". This design is employed in order to produce a circular-shaped pile and the design relies on a central point of rotation on a circular rail.

Stockyard and Disposal Facilities
Combined Stacker / ReclaimersCombined stacker / reclaimers can operate as stackers or as reclaimers. They can stock material in stockpiles and reclaim them with a bucket-wheel at the boom tip.
ReclaimersA variety of different machine types can be employed to reclaim stacked material from stockpiles. Typical machines range from bridge-type bucket-wheel reclaimers to boom-type bucket-wheel reclaimers and drum reclaimers.
