Efficient bucket wheel excavator extracts coal from barge using conveyor system.

A bucket wheel excavator is efficiently extracting coal from a barge docked at a quayside. The conveyor system, equipped with buckets, operates in a continuous loop over the barge. As the buckets descend, they scoop up coal and ascend with their payload. This process is driven by chains and wheels, ensuring a smooth and controlled material handling operation. The design of this system optimizes coal extraction efficiency while minimizing manual labour requirements at the loading site.
