Hydraulic machines are machinery and tools that use liquid fluid power to do simple work. Heavy equipment is a common example. In this type of machine, hydraulic fluid is transmitted throughout the machine to various hydraulic motors and hydraulic cylinders and which becomes pressurized according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses and tubes.
The popularity of hydraulic machinery 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. Hydraulic machinery is operated by the use of hydraulics, where a liquid is the powering medium.
Hydraulic Equipments have many benefits that can make them a much better choice over their alternatives. A hydraulic system can give you lots of power, somewhat accurate control, long durability, provided you are responsible with the maintenance of the whole system. That aspect is perhaps the only downside to using hydraulic Equipments, besides they require a bit more maintenance than usual in order to keep them in a good running condition.
