FOUR ADVANTAGES OF

NO TORSION SPRING INSTALLATION

1.Reduced Costs

No torsion spring system, reduce the whole set of balancedtorsion spring system during installation, material cost savingmore than15% and installation cost reduction more than 30%.

2.Simple and Efficient

New torsion spring-free structure, simple design, easy to installand easy to get started, low coefficient of difficulty for doorinstallation, the commissioning efficiency after door installationhas been increased several times, and the return rate is low.

3.Security Upgrades

No torsion spring system, so that the door body in the operationof the door due to the weight of the wire rope will not be loose,thus ensuring that the wire rope is not easy to scatter, reduceafter-sales and greatly improve the use of the door body safety.Increase the motor brake system level fall arrester, double protec-tion to enhance the safety of the door body use.

4.Anti-theft Upgrade

No torsion spring system, so that the door body in the lowerlimit position due to the weight of the door can not be easilylifted, anti-theft security is greatly improved.
