In the defense industry, Lu and He. Many weapons and equipment of the Air Force have adopted hydraulic transmission and control. Such as aircraft, tanks, ships, radars, artillery, missiles and rockets.

In the machine tool industry, 85% of the current machine tool transmission systems use hydraulic transmission and control, such as grinders, milling machines, planers, broaching machines, presses, shears and modular machine tools.

In the metallurgical industry, electric furnace control systems, steel rolling mill control systems, open hearth furnace charging, converter control, blast furnace control, strip deviation and constant tension devices all adopt hydraulic technology.

In construction machinery, hydraulic transmission is commonly used, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration

Type roller, etc.

In agricultural machinery, hydraulic technology is also widely used, such as combine harvesters, tractors and plows.

In the automotive industry, hydraulic technology is used in hydraulic off-road vehicles, hydraulic dump trucks, hydraulic aerial work vehicles and fire trucks;

In the light and textile industry, plastic injection molding machines, rubber vulcanizing machines, paper machines, printing machines and textile machines are used in irrigation technology;

In the shipbuilding industry, the application of hydraulic technology is very common, such as full hydraulic dredgers, salvage vessels, piling vessels, oil production platforms, hydrofoils, hovercraft, and marine auxiliary engines.

Also in the sun tracking system, ocean wave simulation device, ship driving simulator, earthquake reproduction, rocket-assisted launching, aerospace environment simulation and high-rise building seismic system and tight in recent years.

The emergency brake device is not equipped, and hydraulic technology is also used.

In short, hydraulic technology can be used in all engineering fields, where there are mechanical equipment.
