Construction Machinery: Excavators, loaders, road rollers, and other equipment rely on hydraulic systems for their traveling, slewing, and operating mechanisms. For example, excavators use multi-way valves to control the hydraulic cylinders, enabling bucket digging, boom raising and lowering, and slewing platform rotation.
Industrial Manufacturing: Punch presses, die-casting machines, injection molding machines, and other equipment utilize hydraulic systems to provide high-pressure impact forces. For example, a 630-ton punch press requires a hydraulic system with a rated pressure of 25 MPa to ensure stamping accuracy.
Aerospace: Key actions such as aircraft landing gear retraction and extension, and control surface operation are driven by hydraulic systems. For example, the Boeing 737 landing gear hydraulic system operates at pressures up to 3000 psi, requiring accumulators to buffer pressure impacts.
Agricultural Machinery: Combine harvesters, tractors, and other equipment use hydraulic systems to raise and lower the header, steer, and output power. For example, a tractor's rear suspension hydraulic system can bear a 2-ton load to meet farming needs.
