垂直提升门所用塔伦的半径要比标准提升门所用的平轮半径大，根据材料力学设计原理，同样疲劳次数设计的扭簧，垂直提升门就要比标准提升门选用的钢丝直径偏大。

Vertical lifting door for talen's radius than the standard lifting door with flat wheel radius, according to the design principle of mechanics of materials, the same fatigue design times of torsion spring, vertical lifting door to than the standard lifting door selection of wire diameter is too large.

垂直提升门开启到最大状态下，扭簧还需要一定的扭转圈数来保证门体平衡，总的调整圈数也比标准提升门的调整圈数多。由于调整圈数多了，所以扭簧总长度就会加长，总重量就会加重。
Vertical lifting door is opened to the maximum, the torsion spring also need a certain torsion ring numbers to ensure the door body balance, the total number of ring to adjust also than the standard lifting door to adjust the number of laps. Due to the adjustment of the number of laps, so the total length of the torsion spring will be lengthened, the total weight will increase.
由于扭簧加长后，有时平衡实心轴上的安装距离就不够，这时需要通过放大扭簧内径，缩短扭簧长度，以便流出足够的安装调整距离。
Due to the extension of the torsion spring, sometimes the installation distance on the solid shaft is not enough, then need to enlarge the inner diameter of the torsion spring, shorten the length of the torsion spring in order to flow out enough to adjust the distance.
