Hydraulic systems, use liquid fluid power to perform work. One of the most common examples of a hydraulic powered piece of equipment, is heavy machinery most often seen being used on various types of construction sites. In a piece of heavy equipment, such as an excavator or a man lift, hydraulic fluid is pumped via hydraulic motors & cylinders throughout the piece of machinery, similarly to how blood circulates the human body, and this creates pressurization of the hydraulic fluid. The pressure is then able to be released, obtained, controlled and distributed via hydraulic hoses, tubing and pipes. Hydraulics has become a cornerstone for development in industrialized countries because of the extreme amount of power that can be generated and transferred through conveniently small and flexible hoses.
