Hydraulic systems use the mechanical movement of fluid to build up pressure in a system that then allows for the movement of an object. The force created can be used in the Hydraulic Power Pack that you can find from https://www.hydraproducts.co.uk/Hydraulic-Power-Units/Standard-Power-Units that can then be attached to a number of different equipment pieces to make them work.
Hydraulics can be used in a number of different ways and here are a few of them.
- Lifting – hydraulic arms can be used to lift items that would otherwise be too heavy for a person to lift and this is due to the pressure that is built up by the fluid in the system that then provides the lifting force.
- Braking – these styles of brakes are common in lorries and buses as well as in cars. The brake fluid acts as the liquid needed in this system to exert the force needed on the brake discs and pads to stop the vehicle from moving.
- Aeroplanes – it is hydraulic systems that control the flaps and then landing gear on a plane to help bring the plane to a stop when it lands on the runway. These have to be carefully timed and need to exert large forces to stop the plane safely. Without these systems, it would be impossible to stop a vehicle that large and that is travelling at such high speeds.
