power-cut or emergency, the light drop pull rod, roll door dropped to required location of door smoothly and automatically.
4. a manual switch devices
exclusive double-sided braking systems design, double braking force can be produced .in the brake apparatus with a special high-coil Block respectively were put on activities brakes, brakes, fixed brake pads, and the U-shaped ring. At the end of spring withstood brake activities around the surface of activities brake, and the brakes could be sliding along the axis of the motors, not because of brake pads wear affect braking force.
3. original patent braking systems
reducer device use 2paragraph spiral gear,All special steel gear are used ,then through heat treatment and testing hardness of gear at any time,before out of factory,each motor are through electric integrated test bed,strict inspection to comply with the first-class products and standards with the requirements of national .
2. strict quality control
Motors was installed sensors of the protection device,when the motor temperature is over 100,it automatically cut off power,it immediate supply to the cessation of operation of motor,when temperature down to 70.the motor will automatically recover operation.To protect motor is not to be burned,high-safe. running lower than usual,smooth running with static and stability,Generating vibration frequency voice was relatively lower.In small and light,construction convenient,saving artificial.
