Abstract: Abstract:In order to satisfy the special requirement of the ship lifter dedicated for tourist passenger transport in urban river system connectivity project, a hydraulic lifting ship lifter was proposed. Combining with the urban river system connectivity project of Chizhou, the navigation capacity and the equipment composition of the hydraulic lifting ship lifter were introduced, and the lifting principle and application features of the lifter were analyzed. The result shows that comparing with traditional ship lifters the hydraulic lifting ship lifter has several advantages, which include the simple drive system, the high security, the superior shock resistance, the easy synchronization, the lower cost and so on. The ship lifter can satisfy the requirements of security and stability, and at the same time, it can meet the requirement of urban landscape construction. So the ship lifter is suitable for navigation of urban river system connectivity projects and mediumsmall hydrojunctions.
