​The bucket wheel stacker-reclaimer system adopts the detection technology of adding a scale precise positioning system on the stacker-reclaimer to achieve accurate detection of the position of the stacker-reclaimer. The stacker and reclaimer detected by the scale has high position accuracy and stable signal.

Artificial stacking and reclaiming of coals in the coal yard have a high labor intensity, a low production efficiency, a low degree of automation, etc. Therefore, the problem of improving the low production efficiency of coal stacking and reclaiming and reducing artificial coal reclaiming needs to be solved urgently.

​In the coal yard, there are problems such as high labor intensity, low production efficiency, low safety and low degree of automation, so how to improve the low production efficiency of coal heaping and reduce manual coal extraction is a problem that needs to be solved urgently.

The bucket-wheel stacking and reclaiming machine is mainly a crawler-type mechanical device of material handling. It reclaims materials with bucket wheels continuously and stacks continuously with a belt-type conveyor. It is a machine specially used in the bulk yard to load and unload goods. Stacking and reclaiming machines, reclaimers and bucket-wheel stacking and reclaiming machines are collectively called as stacking and reclaiming machines.
