Stackers are bulk stockpiling machines that are used to stack material in stockyards in different shapes according to specific requirements. A stacker’s function is to stack or pile material on to a stockpile for later reclamation and use - a reclaimer is generally used to reclaim or recover the stockpiled material.
Stackers typically move on a rail between stockpiles in a yard and usually have three directions of movement, depending on requirements:
- Horizontally along the rail
- Vertically by luffing (raising or lowering) the boom
- Slewing, which is rotation of the stacker around its central axis and may not always be a requirement
Our stacker range
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.
Designing according to our client’s unique requirements
Our machines are all specifically designed to our client's unique 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 is fit for purpose. Depending on specific requirements, we are able to supply machines with a boom length of up to 200 m.
Typical design structure
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.
We leverage our years of providing reliable stackers around the world across various commodities and the harshest operating conditions to ensure peace of mind.

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.
Scraper ReclaimersFor a fully automatic operation of bulk storages TAKRAF is offering their field-proven scraper reclaimer technology.
