The system comes with a limiter, and the roller blind automatically stops when it rises/falls to a fixed position

1. The system is equipped with a steel ball locator and a spring system, which work together to pull the lower beam of the rolling shutter forward and achieve its descent. If released immediately, the rolling shutter will lock and stop. If released slowly, the rolling shutter will automatically move up

Raise. If the roller blind stops, pull down the lower beam 2cm and slowly release it, the roller will automatically rise;

2. The system is equipped with a built-in limiter, which sets the maximum height for the roller blind to automatically rise;

3. The system can choose mechanical and hydraulic retarders based on the temperature conditions of the environment in which they are used; Main push mechanical retarder;

4. According to the square meter weight of the fabric, the width and height of the roller blind, different specifications of spring systems can be selected; According to the weight of the lower beam and the expected lifting speed, different springs can be set

Number of pre tensioned coils of the spring;

5. The automatic upward speed and downward effect of the roller blind can be controlled by adjusting the number of pre tightening turns of the spring and the weight of the lower beam;

6. This system does not come with a beam, and the spring can be pre tightened and self-locking. The spring can be unlocked by the buckle on the installation code, thus achieving simple installation; The spring end is equipped with an adjusting device, which can be installed to adjust the

Fine tune the number of pre tightening coils of the spring;

7. Due to the use of a retarder, this system is suitable for a wider range of spring systems of the same specification. It is mainly used for automatic lifting of fabrics with lighter weight, smaller width, and heights below 2 meters

Spring roller shutter.
