If you put your foot down on the brake pedal, the car slows down until it stops. If the brakes don’t work, you are facing a major disaster. Many of the car accidents recorded by authorities are a result of failed brakes because the car owner did not see to its maintenance or forgot to replenish the brake fluid. If there is no enough brake fluid in the cylinders, the brake will not function. Leaks can make the brakes fail and if there is a major leak, the first time you put your foot on the brake pedal, the brakes will have complete failure. These are the brakes used for wheeled vehicles but there are also industrial brakes for a wide range of markets like mining, machinery, manufacturing, steel mills, food and paper industries.
Many industrial applications are concerned with rotary motion that must slow down and rest at a specific time using the industrial brake. Suppliers are continuously improving designs to provide the technical solutions to suit the requirements of industries that have a requirement for industrial brakes.
Functions of industrial brakes
- As a parking brake to regulate or stop an unintended start of a stationary shaft
- For bringing a rotating shaft to a standstill in short time usually in connection with an unanticipated power failure or an emergency stop
- As a control brake to maintain a specific tension in the material
The types of industrial disk brakes
- Manual brakes that are used for stopping, holding and tension duties when there is no air supply available
- Hydraulic brakes are advanced products with excellent performance and functionality. Due to the advanced functions that are applied to them like the automatic shoe clearance balancing and wear-self-compensation device, they are definitely considered as maintenance friendly. This industrial brake fits well for decelerating, stopping/braking modern machines used in large scale industries where there is loading and unloading of machines, lifting and transporting heavy machinery, metallurgy and mining equipment.
- Pneumatic brakes have high torque capacity which when applied stops the application of industrial equipment. It uses an actuator in between two caliper arms that allows the brake to have a compact physical size in relation to the torque capacity. Pneumatic brakes are used in many large scale industries that use wind turbines, conveyors, textile machinery, test rigs, bulk material handling equipment and mines special purpose machine including industries like nuclear power plants and tire industries.
- Electromagnetic brakes are designed for high consistent applications from copy machines to conveyors. Other applications include packaging machinery, printing machinery, food processing machinery and factory automation. These industrial brakes operate through an electric actuation but transmit torque mechanically. Once voltage or current is applied, the coil becomes energized creating a magnetic field. This turns the coil into an electromagnet that develops magnetic lines of flux that attracts the armature to the face of the brake. In most designs, springs hold the armature away from the surface of the brake when power is released to create an air gap.
