Description :

1. Product: Rolling Door Motor-300KGS
2. Applicative range: General electric rolling doors
3. Overheating protective device
Built-in precision heat detector prevents motorfrom over-heating during the rolling operation in case of a malfunction as itautomatically cuts off at 100 degree and stops the motor from running idle.Operation resumes when temperature drops to 70 degree, great feature thatprevents damage to door or impact to the motor.
4. Anti crinkle protective device
Selective feature that weighs down the doorwithout using electric power during closing motion; no crinkling or recoilingwhen jammed object to protect the door.
5. Emergency manual stop
Easy, light operation that employs weighing downor up chain-pulling in case of power outage.
6. Operating safety protective device
A built-in disk magnetic braking system thatdisengages the chain disk from motor shaft, while the current must be disruptedbefore the motor can be restarted to protect operating safety.
