Yu-Chen Hydraulic Industrial Co., Ltd. has two working teams, who have experience in practical one-time small-aperture propulsion construction at Keelung, Beitou, and Zhunan Township in Miaoli County. We completed the tube propulsion practice by using the machines and equipments developed and manufactured by ourselves. Currently, the two teams are both working in Zhunan Township in Miaoli County, and in 2014, they succeeded in completing the making of more than 2000km of tube propulsion! The machines and equipment they used include: propulsion platforms, sand filtering machine, propellers, oil hydraulic power sets, and other related equipments, all of which are produced and manufactured by us.
