卷帘门在上下启闭的时候查看清楚是否有堆物，非常是防火卷帘门是和消防系统联动的，经常会因为操作不当导致防火卷帘门损坏，或倾斜。而普通的也应该非常注意，门帘在开闭的同时应该人在现场，万一出现门帘倾斜或者轨道卡位应该及时停止门帘开闭，这样才不会给电机和门帘造成更大的伤害。

　　When opening and closing the rolling shutter door, check carefully for any debris, especially since the fireproof rolling shutter door is linked to the fire protection system. Improper operation often leads to damage or tilting of the fireproof rolling shutter door. And ordinary ones should also pay special attention. When opening and closing the door curtain, people should be present on site. In case of door curtain tilting or track jamming, the door curtain opening and closing should be stopped in a timely manner to avoid causing greater damage to the motor and door curtain.

　　卷帘门电机的选购也是比较重要的一个环节，切记不要感觉提升力够用就行，因为卷帘门电机的承载力会随着时间的推移，会慢慢的降低实际的提升功效，所以选材方面尽量的要超过门帘的实际提升力。门帘在开闭的同时，严禁行人及奔跑，因为门帘在开闭的时候门帘是通过联片连接的，而电机和传动轴也是存在很少的不安全因素。所以门帘在启动的时候应该尽量不要有人跑动。商家在选材方面也应该多考虑，轻便，坚固耐用的材质，这样即使在特殊情况下也能起到较高的安全问题。

　　The selection of the motor for the rolling shutter door is also an important step. Remember not to feel that the lifting force is sufficient, because the bearing capacity of the rolling shutter door motor will gradually reduce the actual lifting effect over time. Therefore, in terms of material selection, try to exceed the actual lifting force of the door curtain. During the opening and closing of the door curtain, pedestrians and running are strictly prohibited, as the door curtain is connected by a connecting plate, and there are few unsafe factors in the motor and transmission shaft. So when the door curtain is activated, try not to let anyone run. Merchants should also consider more when selecting materials, such as lightweight, sturdy, and durable materials, so that even in special circumstances, they can still have a high level of safety issues.
