工业门提升方式分为上滑道提升，完全垂直提升和半垂直三种，其扭簧安装如下。

Industrial door promotion way is divided into the upper slide, completely vertical and vertical three and a half, the torsional spring installation is as follows.

1 in the following, the hydrodynamic (closed) : torsional spring one end fixed and the other end around to install the required number of turns, then push the adjustment of the torsional spring end to the fixed end, and tighten the adjustment screw on the flange.

2、门体放在上面（即开启状态）:将扭簧一头固定，沿调节端将扭簧拉长60～120mm，再预紧0.5～1圈，最后用螺钉将扭簧调节端固定在轴上。扭簧为什么要拉长呢？因为在门体提升过程中，扭簧外径会变小，圈数会增多，因此，拉长弹簧使其有一定的间隙，便于提升门体。

2 on the above, the hydrodynamic (open) : the torsional spring a fixed, torsional spring stretched along the adjusting end into 60 to 120 mm, 0.5 ~ 1 lap to preload, the torsional spring adjustment with screw finally end fixed on the shaft. Torsional spring why spin? Because the door in the process of ascension, the torsional spring diameter become smaller, circle number increase, therefore, stretched spring, there is a certain gap to improve body.

完全垂直提升工业门扭簧安装时需要预紧。钢丝绳的长度必须根据塔轮线盘来确定，要保证门体开启到顶部时，钢丝绳在塔轮上从大圈到小圈全部绕满。

Completely vertical torsional spring industrial door installation need preloaded. The length of the wire rope must be determined according to the cone line plate, to ensure that the door open to the top, the wire rope on the cone from the circle to the small circle all around.

完全垂直山东提升门

Completely vertical industrial door: because the torsional spring is always under the unity of the weight of the hydrodynamic, only by changing the size of the wheel diameter, the size change torque, to make the torsional spring torsion and door weight balance, so need to install the cone.

Half vertical industrial door: need to install a half step pulley to make the torsional spring torsion and door weight balance. The door is vertical with half cone cone part; Sliding door ascends with half cone flat wheel parts.

Half of vertical industrial door torsion spring when installation should be preloaded. Of wire rope winding method is: from the first half of the cone around the small circle, the circle and go around, and then continue to around half cone flat wheel, the number of turns on the flat wheel, according to the hydrodynamic sliding part of the hoisting height to determine.
