提升门采用扭簧平衡，平衡扭簧为专业弹簧厂根据门重负荷计算而设计制作的扭簧，使平衡达到最佳状态。提升门的扭簧材料选用日本进口铃木优质60Si2MnA弹簧钢制作确保使用寿命超过30000个循环周期。表面发黑防锈处理。

The lifting door adopts a torsion spring balance, the balance torsion spring is a torsion spring designed according to the door heavy load calculation, so that the balance can reach the optimum state. The lifting door of the torsion spring material selection of Japanese imports of SUZUKI quality 60Si2MnA spring steel production to ensure that the service life of more than 30000 cycles. Black surface rust treatment.

提升钢丝绳轮，标准提升门采用圆柱形绳轮。轴杆采用热镀锌钢管，二轴端为实心圆钢，在提升门平衡轴上装有扭簧断裂保护装置，该装置能在平均扭簧断裂时，防止提升门门板坠落。

A cylindrical rope wheel is adopted for the standard lifting door. Shaft uses hot galvanized steel pipe, two shaft is a solid round steel, the lift door balance shaft with twist spring fracture protection device, the device can in average twist spring fracture, to prevent the lifting door door plank is falling.

提升钢丝绳安全系数大于提升门重的5倍，并在提升门门板上设置钢丝绳断裂、速度监控保护装置，确保提升门门板安全运行。

The safety factor of hoisting rope is 5 times larger than that of lifting door, and the fracture of steel wire rope and the speed monitoring and protection device are arranged on the door panel of the door to ensure the safety operation of the door and door.
