The colleagues who install the roller shutter door all know that the center lines on both sides of the roller of the electric roller shutter door are kept in a horizontal line. Only in this way can the curtain pieces of the electric roller shutter door run smoothly and not deviate in the process of operation. But in the process of processing and installing the electric rolling shutter door, how can we do it.

济南富强门业在长期实践中，总结了自己的经验，在此与大家共同分享一下。，电动卷帘门卷轴两侧的承重铁板线也要安装在一条水平线上，而且线到墙面的距离要保持等值。

Jinan Fuqiang door industry in the long-term practice, summed up their own experience, here to share with you. First of all, the center line of the load-bearing iron plate on both sides of the roller of the electric roller shutter door should also be installed on a horizontal line, and the distance from the center line to the wall should be kept equal.

其次，卷轴有轴承一侧的铁棒，在内外伸缩过程中，要保持在一条水平线上，而且，在卷轴运行过程中，铁棒不能松动、弯曲，为了做到这点，我们在卷轴两侧的承重铁圈及轴内部的平衡铁圈都焊接了铁片，保证铁棒伸缩自如，又保重了卷轴各个部位的水平稳定性。

Secondly, the iron bar on the bearing side of the reel should be kept on a horizontal line in the process of internal and external expansion. Moreover, during the operation of the reel, the iron bar should not be loose or bent. In order to achieve this, we welded iron sheets on the bearing iron rings on both sides of the reel and the balance iron rings inside the reel to ensure that the iron bar can expand freely and the horizontal stability of all parts of the reel 。
