Reasons for jammed faults of fast rolling doors

The fast rolling door is used by many customers because of its beautiful design, perfect function and convenient operation. However, sometimes the rolling shutter door may suddenly get stuck. If there is a problem, it needs to be solved. But before solving the problem, it is necessary to find out the reason. What may be the reason for this phenomenon? Below we give you a brief introduction.

The reasons for the jamming failure of the fast rolling door are as follows:

1. The limiter has run too far: the limiter of the rolling door crane is generally divided into upper limit and lower limit. In the case of a sudden power failure in some cases, the maintenance of the rolling shutter door has only to pull the chain to open and close the door, or open the automatic drop lever to close the door. At this moment, if you don't pay attention to whether the limit switch is in place, it may cause the limiter to run too far. Generally, if the lower limit runs too far, then the next time there is power on, there will be a situation where only the upper limit cannot be lowered; The situation that cannot be used is stuck. It is very simple to solve this kind of situation, as long as the limit switch is adjusted again within the reasonable limit range.

2. It may be that a certain line in the manipulation route is not connected properly or is pulled out. Each roller shutter door crane has been inspected by the original factory, and the probability that it is not connected is very small. It may be torn off during the transportation or installation process. We also found that some installation masters use the lead wire of the rolling door crane as the handle to lift the motor. This kind of practice is wrong, which usually causes the motor wire and the power plug of the relay to fall off, resulting in the phenomenon of jamming. .

The main reasons for the jamming failure of the fast rolling door are the above two points. If it is a person who is not familiar with it, it is better to find a professional person to adjust it, which is safer.
