Description
technical field [0001] The invention relates to the field of hydraulic technology, in particular to a high-efficiency hydraulic device. Background technique [0002] As we all know, hydraulic transmission technology is widely used in industrial and civil industries due to its large transmission force, flexible control, easy transmission and configuration. With the continuous development of hydraulic technology and the development trend of ships, hydraulic technology is more widely used in the field of ships. The mooring winch can also operate effectively when the ship is moored or moored to the shore, and has many functions such as drifting, supporting and positioning during loading and unloading, and at the same time compensates for vibration with constant tension adjustment. deviation. An example of an application of the constant tension adjustment feature is a mooring winch installed on shore for loading or unloading of a mooring vessel. According to power, winches are ...
