they are used when a heavy weight has to be lifted, for example, when a car is lifted in a garage so that the mechanic can see the bottom of the car. they can also be used in mountain bikes and car brakes use hydraulics.
· Hydraulic equipment manufacturers produce various types of equipment that find application in numerous machinery - visit http://in.kompass.com/a/hydraulic-equipment/32580/ to know the diff type of hydraulic machinery
A hydraulic machine is a machine that is powered by hydraulics fluids. The hydraulic system can produce a lot of power from small equipment.
They are used to seal motors or machines and rotatin pump shaft or hydraulic cylinder pistons.
Pascal's Principle
hydraulic is liquid based, pneumatic is air.
The incompressibility of most liquids.
Hydraulic oil and hydraulic fluid are different. Hydraulic fluid is used in small systems such as car brakes. Hydraulic oil is used in large systems such as loaders.

Pascal's Principle
Hydraulic machines are useful in construction as they are force magnifiers. This means that a small input force can be made into a large input force. ^_^
hydraulic is liquid based, pneumatic is air.
The incompressibility of most liquids.
Hydraulic machines rely on the low compressibility of a specific fluid. When the fluid is pumped into the cylinder that does the work and then sealed, the fluid's inability to compress ensures that the cylinder does not lower from the position is was moved to.
Instead of hydraulic pumps, hydraulic gear motor does not work. Hydraulic pump hydraulic motor blade is used instead.

gasses can compress, so a hydraulic pipe would be useless. In fact, the hydraulic pipe was invented just for water, hence the "hydra" part. Liquids cannot compress, instead they push out, so they are great for machines ( like brake fluid).
