Electro Hydraulic Thruster Drum Brakes

Electro Hydraulic Thruster Drum Brakes

Electro Hydraulic Thruster Drum Brakes (commonly called thruster) are device used to retard the speed of moving machinery and to stop it accurately to the desired position. When the braking force is applied to the brake shoes by a pre-stressed compression spring, the shoes press on the rotating brake drum retarding its speed and finally stopping it. The releasing of the brake drum and compressing of the spring is done by the thruster.

Thruster operated drum brakes are mainly used in material lifting and handling equipment (in the field of applications like ports, steel and metallurgy, mining, etc.) mainly because their “soft / smooth” braking and 'fail-to-safety' designs to ensure safety to men and machines.

These brakes are called 'fail-to-safety' because the braking is obtained by electrical current loss under the action of pre-stressed compression spring. In case of current loss (power failure), these brakes stop the motor or the driven load.
