电动卷闸
关于电动卷闸
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

车库门
卷闸
为什么我们不建议用卷闸来做车库门？
车库门使用扭力弹簧来平衡车库门的自重， 故此开门器只需要克服摩擦力便可轻易地打打开或关闭车库门. 另一方面， 标准的车库门开门机使用动力导轨， 从门的中央用力， 更有利于平衡. 卷闸也可以使用开门机， 但是卷闸的马达只能安装在旁边. 由于这样很难做到平衡， 会产生噪音而且容易坏. 在美加，欧洲等先进地区， 已没有人使用卷闸来做车库门.
