One of the best places to get up close and personal with large hydraulic machines is at a construction site. The thing that is most amazing about these machines is their sheer size. For example, here is a medium-size shovel/excavator:
Hydraulic machinery are machines and tools that use fluid power to do the work. Almost all types of heavy equipment is a common example. With this type of equipment, hydraulic fluid is pumped to a high pressure then transmitted through the machine to various actuators.
In order to drive or operate certain machinery, the hydrostatic drive system is used. This system makes use of a hydraulic fluid under pressure, making it easier to operate such mechanisms. Also known as the hydraulic power transmissio.
