Designed for decline conveyors with a fail-safe requirement, the EC100 RollerDrive from Interroll Corp. (Wilmington, NC) has a mechanical rotor locking break that prevents drifting on inclines while ensuring smooth operation, low-noise emission, and an extended operating lifetime. The EC100B brake mechanism requires no special control, as two wires are simply attached to the main power bus. The new technology comprises a mechanical rotor-locking break, which is spring-loaded and does only cycle with main power. The brake does not cycle with each start and stop of the conveyor. As long as the power bus is on, the magnetic force created by the solenoid keeps the rotor free.
