What should we pay attention to in the track installation of industrial roller shutter? Track is the main part of industrial door switch, once the track is welded
Improper connection or deformation will have a great impact on the overall operation of the industrial door. Today, the small technical director of Mingxin door factory said the requirements of door track installation.
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.
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.
In addition, the lateral dislocation and height difference of the two rails at the joint should be less than or equal to 1 mm.
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.
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.
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.
The above is to introduce the track installation of industrial roller shutter door matters needing attention. I hope you can increase the further understanding of rolling shutter door after reading. If you want to purchase or want to know more, please contact us.
