Bunker Door for Self-Shielding Cyclotron The SFM doors have a COMECER electro-mechanical operating system, which includes two steel wheels sliding and rolling on suspended wall guides and a moving system with gearmotor-pinion-rack. The gearmotor is self-locking and maintains the door in a closed position during normal working conditions. The door can be manually unblocked thanks to the electro-magnetic joint inserted between the gearmotor and the pinion, if the emergency button is pressed or when there is no electricity supply.
