上滑式车库门按照洞口上方的空间可分为单轨和双轨两种，但是它和上排挂车库门的运行方式都是一样的，它在启动的时候，门体在轨道运行且垂直直线上升。
According to the space above the opening, the up sliding garage door can be divided into single track and double track. However, the operation mode of the up sliding garage door is the same as that of the upper row hanging garage door. When it is started, the door body moves in the track and rises in a vertical straight line.
它由平衡系统、固定导轨和多块门板连接而成，门侧边装有滚轮，开启时门沿导轨运动，向上转折提升，门内置扭簧，扭力和门重量相当，使门体处于“零重量”状态，且在轨道内靠滑轮运行。
It is connected by a balance system, a fixed guide rail and a plurality of door panels. A roller is installed on the side of the door. When the door is opened, it moves along the guide rail, turning upward and lifting. The door is equipped with a torsion spring, the torsion is equivalent to the weight of the door, so that the door body is in the "zero weight" state, and it runs in the track by a pulley.
