Abstract
Disclosed is an energy-saving bidirectional ship lift by gravity balancing, including: a ship lift body. A first support is provided in a middle of the ship lift body. A second support is provided at a side of the first support. A third support is provided at the other side of the first support. A space between the second support and the first support forms a first shaft. A space between the first support and the third support forms a second shaft. A first ship-carrying chamber and a second ship-carrying chamber are respectively provided in the first shaft and the second shaft to allow two ships to be transported at the same time. An entry water tank and an exit water tank are provided at two sides of each ship-carrying chamber to adjust the weight of the two ship-carrying chambers.
