济南遥控卷帘门的弹簧断了怎么修复，以下是操作方法

How to repair the broken spring of the remote control shutter door? Here are the operation methods

扭簧的安装方法是：首先用手抓住扭簧的外壳，面对人的时候（从正面）再向上抓。

The installation method of the torsion spring is as follows: first grasp the shell of the torsion spring by hand, and then grasp it upward when facing people (from the front).

左手握紧扭簧，然后右手用扳手卸下固定在门体上的螺丝（松松），然后用双手慢慢卸下。慢慢松开弹簧，直到没有阻力为止，以此类推各。

Hold the torsion spring with your left hand, and then use your right hand to remove the screws (loose) fixed on the door body with a wrench, and then slowly remove them with both hands. Slowly release the spring until there is no resistance, and so on.

然后把手动横梁两侧的卷靠（横梁）螺丝卸下来，然后把它拿下来，再把手动遥控卷帘门的弹簧螺丝卸下来，然后把新的也按照卸下来的厦门弹簧设置好，当然固定螺丝也是按照老办法都安装好后。

Then remove the roll back (cross beam) screws on both sides of the manual cross beam, then remove it, then remove the spring screws of the manual remote control rolling shutter door, and then set the new ones according to the removed Xiamen spring. Of course, the fixing screws are also installed according to the old method.

现在要拧紧弹簧了，这是关键的操作（其实之前拆的时候是反方向的）。将弹簧拧紧到需要的阻力，然后更换螺丝。

Now it's time to tighten the spring, which is the key operation (in fact, the previous disassembly was in the opposite direction). Tighten the spring to the required resistance, and then replace the screw.

钢叶弹簧的更换首先用手握住扭簧的弹簧壳面向人的方向（从正面看），向上一定要握紧，左手握住后右手取下挂钩（如果是手动遥控卷帘门弹簧坏了则只需取下挂钩就行了）。

To replace the steel leaf spring, first hold the spring shell of the torsion spring with your hand facing the direction of people (looking from the front), and then hold it upward. After holding it with your left hand, take off the hook with your right hand (if the manual remote control shutter door spring is broken, just take off the hook).

然后把弹簧往下拉（取下来），钢套建议比门体长80厘米。然后拆掉之前的螺丝，安装好门弹簧，将弹簧拧紧到佳阻力，挂上挂钩。

Then pull the spring down (take it off). The steel sleeve must be 80 cm longer than the door body. Then remove the previous screws, install the door spring, tighten the spring to a good resistance, and hang the hook.

其实钢弹簧和扭簧的基本原理是一样的，一般用户换弹簧的注意点是在使用遥控卷帘门时突然拉不起来了。

In fact, the basic principle of steel spring and torsion spring is the same. Generally, users should pay attention to the fact that the spring can not be pulled up when using the remote control shutter door.
