The concept behind a hydraulic system is simple. The fluid sued in the system is the hydraulic oil. A hydraulic system has two or more cylinders that are connected to a single pipe containing the oil and the pistons that helps in pushing the fluids in the cylinders.
Hydraulics is used in many machines that we see in our daily lives. Some of its uses are:
- Hydraulics is used in heavy equipments like log splitters. You can find the simplest hydraulics system in log splitters as it consists of most of the components of a basic hydraulics system such as the hydraulic pump, an engine, the hydraulic cylinders, the various valves and the hydraulic pistons.
- The heavy- duty machines make use of the hydraulics system that is often seen at construction sites and other excavations. A large machine such as the excavator may weigh anything around thirty tons but it has the capacity to move around easily and carry mud weighing about two tones without any difficulty. An excavator has a motor for each of its tracks and a motor for swinging its huge arm that all runs on the system of hydraulics. Other construction vehicles making use of hydraulics system include the loading machines, also known as the skid. This machine makes use of 3 pairs of hydraulics pistons and also hydraulics motors on each of its four wheels. Another vehicle that we often see in our daily routine are the garbage dump trucks. They make use of all the hydraulic components. The only exception in its case is the use of telescopic cylinders that helps them to attain the feat of positioning the dump bucket to an almost vertical stance to allow the garbage fall over.
- Hydraulics is also used in mechanical wheel chairs to push the wheel chair forward. It is also used for aircraft landing gears to push the wheels out when landing the plane.
