Combined Stacker / Reclaimers
Combined 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.
TAKRAF combined stacker / reclaimers with bucket-wheel boom are primarily employed where medium or large or very large material flows are to be stacked and then later reclaimed by the same machine. Our typical machines cover the following flow rates and sizes:
- Stacking and reclaiming capacity: 500 t/h to 20,000 t/h
- Rail gauge: 6 m to 20 m
- Boom length: 25 m to 60 m
Our machines are all specifically designed to our client's requirements and incorporate various solutions according to their specific application.
Fixed Rocker Arrangements for Low or Medium Flow Rates
In applications involving low or medium flow rates and/or medium length booms, machines in which the bucket-wheel and counterweight boom are combined in a fixed rocker arrangement are generally preferred. This arrangement results in a reduced number of articulation points.
An integral part of the machine is the tripper car and integrated conveying system which transports material to the bucket-wheel boom and then to the stockpile. The tripper car and conveying system is often equipped with a "bypass function" that enables material to bypass the boom and continue along the conveyor system.
Pantograph Arrangements for Higher Flow Rates
Where higher flow rates and/or longer boom lengths are required, we prefer a machine design in which the bucket-wheel and counterweight boom are combined in a pantograph arrangement. The pantograph arrangement ensures that with large boom loads, small changes in the point of balance are stabilized, which has a significantly positive impact on machine steadiness. A drawback with this design however is the increased number of articulation points.
Semi-Automated and Automated Machines
The majority of our combined bucket-wheel boom machines are semi-automated; however, there is a growing trend towards full automation and we are able to supply fully automated machines too. These machines incorporate further control systems and sensor logic and are controlled and monitored from a central control station.
- We design, fabricate and supply a wide-range of machine capacities from 500 t/h to 20,000 t/h with boom lengths ranging from 25 m to 60 m
- Our machines can be specified as fully automated and thus work in the absence of an operator through a variety of sensors and are controlled from a central control point
- For large conveyance applications, we prefer a pantograph construction for our machines which increases machine stability
