What should we pay attention to in the track installation of industrial roller shutter? Track is the main part of industrial door switch operation. Once the track is welded improperly or deformed, it will have a great impact on the overall operation of industrial door. Today, the small technical director of Fuqiang door manufacturer said the requirements of door track installation.

一般情况下，工业卷帘门轨道接头可以做成直角或45度斜角接头，斜角接头能使门上的大轮子在接头处平稳过渡。

Generally, the rail joint of industrial rolling shutter door can be made into right angle joint or 45 degree bevel joint, and the bevel joint can make the big wheel on the door transition smoothly at the joint.

一般情况下，钢轨接缝为1-2mm，如果是在寒区冬季施工或安装前温度低于常年使用温度2℃以上，安装卷帘门钢轨时应考虑温度缝，在单钢轨长度1m左右，应选用4-6mm。

Generally, the rail joint is 1-2mm. If it is constructed in winter in cold regions or the temperature before installation is more than 2 ℃ lower than the annual service temperature, the temperature joint should be considered when installing the rolling shutter rail. When the length of single rail is about 1m, 4-6mm should be selected.

另外，连接处两轨的横向错位和高低差应小于等于1mm。

In addition, the lateral dislocation and height difference of the two rails at the joint should be less than or equal to 1 mm.

同样截面上的工业卷帘门轨道面高低也会有误差，虽然这一误差也有相应的标准，即柱出距不小于1mm，其它地方不小于15mm，门式起重机、跨度大于4m的门式起重机和装卸桥不小于15mm。

The height of the track surface of the industrial roller shutter door on the same section will also have errors, although there are corresponding standards for this error, that is, the column spacing is not less than 1 mm, other places is not less than 15 mm, and the gantry crane, gantry crane with a span of more than 4 m and loading and unloading bridge are not less than 15 mm.

但在同一侧的工业门轨道面上，两柱之间的高度与相邻柱之间的高度之差不超过B/15mm，但大不超过1mm。

However, on the same side of the industrial door track surface, the difference between the height between the two columns and the height between the adjacent columns is not more than B / 15mm, but not more than 1mm.

对于轨道跨度、轨道与承轨梁、轨道不直等方面的误差，应以轨道安装误差表为准，切勿对不能安装的误差表值进行计算。

For the errors of track span, track and rail bearing beam, track straightness, etc., the track installation error table shall prevail, and the value of error table that cannot be installed shall not be calculated.
