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 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

Other typical applications, not covered in detail include:

Elevators

Dampers used for vehicle suspension

Ship anchor windlasses
