Single-disc brake / spring-applied / electromagnetic release / security
CHAIN TAIL CO., LTD.
The ABS series is a range of brakes manufactured by Chain Tail Co. They have a layout that causes the spring of the coil to hold the brake piece in place. It creates braking torque by means of its friction.
The tension of the coil spring will cause the armature to handle the brake when the magnetic current is no longer available.
