Industrial lifting doors cannot be separated from the balancing effect of the spring system. However, if the spring balance system is used for a long time, it will also cause problems of being too loose or too tight. At this time, professional and technical staff are required to debug and deal with it.

Industrial lifting door can not be separated from the balance of the spring system, but the spring balance system for a long time, will also appear too loose or too tight problem, then need professional and technical staff to carry out debugging.
Generally speaking, when it comes to industrial lifting door spring system, there is only the subject of adjusting the tightness. There are different ways to adjust the spring loosening and tightening. The details are as follows:
industrial door spring tightening method:
This adjustment process is extremely complex and requires the cooperation of two people. When manipulating, first clamp the shaft around the tight spring seat with full-force pliers, then one person inserts the tight spring rod into the tight spring seat to stabilize it upward, and the other person loosens the two square screws on the tight spring seat, and then The other tight spring rod is inserted into the other tight spring hole, and the two people lift up equally. After reaching the predetermined number of turns, use a square screw to lock the spring in the keyway of the shaft, and another screw to lock the shaft. If the spring is adjusted too tightly, it needs to be loosened and readjusted.
industrial door spring loose method:
Like the tight spring, this manipulation process also requires two people to cooperate to complete. The first step of the manipulation method is the same as the spring tightening above. In addition, when loosening the spring, for the sake of safety, it is recommended that you add and subtract every half circle and half circle on the basis of the original number of circles. At the same time, you should stop and try every time you add and subtract, and then judge whether you still need to inherit to increase or decrease the number of circles. Do not increase or reduce the number of turns of the spring at a time, otherwise the spring is too tight, the door body of the industrial door will rush out of the track.
