Stockpiling with a Stacker
To begin off: What is a stacker? Stackers are bulk stockpiling machines that are used to stack or heap material in stockyards in different shapes according to specific requirements. A stacker’s function is to stack, heap or pile material on to a stockpile for future reclamation.
Stacker functionality
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 material. The structure of the stockpile is dependent on the specific requirements of the various bulk processes, ie. chevron, windrow, strata or cone shell.
Tailored stacker systems
Our machines are all specifically designed to our client's unique requirements and incorporate various solutions according to their specific application, including any specific automation requests, such as an automated storm lock for gust winds.
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.
We also offer combined stackers and reclaimers.
Typical design structure of a stacker
Our machines generally boast a typical design structure and include a hydraulic lift system and counterweight at the rear end of the boom - this often leads to them being classified as a "balanced machine" in some countries. Nonetheless, we have also built machines to handle ore which boast an L-frame, a rope winch and a horizontal swivel boom. Also, as mentioned, we offer machines with or without the ability to slew.
Radial stacker
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 numerous stackers around the world across various commodities and the harshest operating conditions to ensure peace of mind and superior operational efficiency. Let us show you why we are the stacker company of your choice.

Stackers for coal in Australia
Customer Project Name Caval Ridge BMA – BHP Billiton Mitsubishi Alliance 2014 Stackers with an elevator conveyor
These two stackers are operating with one reclaimer on the same rail track. The two stackers have one feeding conveyor. Therefore the first stacker in the line is equipped with a bypass system. Both stackers have an elevator conveyor and are of the slewable and luffable design. These machines can be operated in automatic mode from the control room or in remote mode.
