On the Mechanism Analysis of the Vertical Shaft Type …

Vertical shaft type wind-power Chinese square-pallet chain-pumps are Chinese square-pallet chain-pumps that are powered by vertical-sail-type Chinese windmills (Chinese great windmills). These apparatuses had been widely-used for raising water in agricultural fields and salt fields along the coast of China since the 12th century until the 1980s, when they went completely extinct.
