Hydraulic systems examples

Hydraulic systems are basically machinery and tools that use liquid fluid power to do simple work, operated by the use of hydraulics, where a liquid is a powering medium. In heavy equipment and other types of hydraulic machines, hydraulic fluids transmitted throughout the machine to various hydraulic motors and hydraulic cylinders and become pressurized according to the resistance present.

The fluid in hydraulic systems is controlled directly or automatically by control valves and distributed through hoses and tubes.

The popularity of hydraulic systems is due to the very large amount of power that can be transferred through small tubes and flexible hoses, and the high power density and wide array of actuators that can make use of this power.

To control hydraulic system hydraulic valve is especiallnsist of a spool inside a cast iron or steel housing. The spool slides to different positions in the housing, and intersecting grooves and channels route the fluid based on the spool's position.

Lifting equipment also known as lifting gear is a general term for any equipment that can be used to lift heavy loads. This includes jacks, block, and tackle, vacuum lifts, hoists, rotating screws, gantries, gin poles, shear legs, sheerleg, windlasses, lifting harnesses, forklifts, hydraulic lifting pads, air lift bags, and cranes.

Lifting equipment can be dangerous to use and is the subject of safety regulations in most countries.

Lifting and excavating arms on machinery such as diggers. Lifting equipment includes any equipment or machinery used at work for lifting or lowering loads or people, including accessories and attachments used for anchoring, fixing or supporting the equipment. There is a wide range of lifting equipment in the construction industry which uses hydraulic systems.

Hydraulic presses - machine press use a hydraulic cylinder to generate a compressive force. It uses the hydraulic equivalent of a mechanical lever.

Wing flaps and some rudders on aircraft and boats. Flaps are a type of high-lift hydraulic system device used to increase the lift of an aircraft wing at a given airspeed. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used for an extra lift on takeoff and also cause an increase in drag in mid-flight, so they are retracted when not needed.
