In this presentation you will see examples of where hydraulics are used in real world applications.
Hydraulic Applications
Uses of Hydraulics
Hydraulic systems are used where large, precise forces are required.
Vehicle power steering
Dump trucks
Flight simulators
Hydraulic jacks
Heavy earth moving equipment
Vehicle brake systems
Common examples include:
Next >
Hydraulic Applications
Engine power
Hydraulic pump
Actuatingcylinder
Landinggear
Example: Aircraft Hydraulic Systems
All modern aircraft containhydraulic systems to operate mechanisms, such as:
Landing gear
Hydraulic power is provided by a pump that is coupled to an engine. Power is distributed to systems throughout the aircraft by transmission lines.
Hydraulic power is converted to mechanical power by means of an actuating cylinder or hydraulic motor.

Which aircraft system is NOT powered by hydraulics?
Question
A) Landing gear
B) Propulsion
C) Wing position
D) Flaps
Hydraulic Applications
This pressure forces the brake pads against the brake rotor, which is rotating with the wheel.
The friction between the brake pad and the rotor causes the wheel to slow down, and eventually stop.
The function of a vehicle braking system is to stop or slow down a moving vehicle.
Example: A Vehicle Braking System
When the brake pedal is pressed, hydraulic pressure is transmitted to the piston in the brake caliper of the brakes.

Hydraulic pressure pushes what, to squeeze the brake pads?
Question
A) The rotor
B) The caliper
C) The piston
D) The brake pedal
Hydraulic Applications
Example: Industrial Hydraulics
Next >
Hydraulic systems are widely used in industry. They may be integrated with pneumatic and or electromechanical systems.
Typical applications include:
Presses
Platform hoists
Hydraulic motors
Jacks
Hydraulic Applications
Example: Construction Machines
Next >
Construction machines use hydraulics to move heavy loads. Hydraulics in construction machines can be used to move a large load, with a small force.
All of these machines use hydraulic pressure to move powerful cylinders that operate buckets, booms, blades and raise beds.
Typical machines include:
Skip / loaders
Dump trucks
Excavators
Cranes
Hydraulic Applications
Other Systems
Next >
Other typical applications, not covered in detail include:
Elevators
Dampers used for vehicle suspension
Ship anchor windlasses
