Electro-Magnetic Thruster Operated Drum Brakes
Material Handling Equipment.
The brake assembly contains of a brake arm, brake shoe, base frame, actuating lever, brake spring, and an electromagnetic thruster. The brake shoe is mounted on the brake arm and the gap between the brake drum and brake pad is adjusted by spring mechanism. A spring, suitable to give the required braking force, is mounted inside the thruster. All the components are mounted on to the base frame
The brake is a failsafe type. Normally the brake will be in applied condition, due to the spring force on the brake arms. When the power supply is on, an electromagnetic force is developed in the coil, which pulls the plunger against the spring force. When the plunger is pulled, the spring is compressed and the brake arms move away from the drum thus releasing the brake. When the power is switched off the electromagnetic force become nil and the brake is applied by spring force
