Standards to enhance shutter spring balance system

The device includes a pendulum claws, torsion, and by the board, put claws installed in the electric rolling door between the size of the sprocket, one end of torsion spring shaft bearing hole in the wall place claw [CS23950-0712-0353] escape the mist fire shutter doors [ CS23950-0344-0354] rolling door shutter with a helical torsion spring device
    Improve the standard spring balance shutter doors sliding door system in dealing with the balance, the general use of torsion spring balance system Shike (torsion spring and wire wheels) in the spring calculation processing of the case correctly, the installation should be first installed and the door so that the door is fully closed and then tighten the spring plate H
    A shutter down and the rope to prevent the dislocation of the shutter device (511813-1136) shutter spring sets (511813-1135) a shaft one hundred security for the flexible planar fabric fixed to the reel means and shutter ( 511813-0938) shutter door locking device locking structure
    Torsion spring in the shutter installation plays an important role and value of, the need to ensure production quality and performance of torsion spring in the torsion spring to do after the processing of correct calculation of the spring case, in the installation, the door should be installed first and to the door is fully closed and then tighten the spring plate H
