电动伸缩门的智能红外探头防撞装置，遇人或异物30-50cm，可自行返回运行，从而保障车辆及行人的安全。电动伸缩门可以选用电子软启动与机械缓冲装置配合使用，启闭时主机不摇晃且运行顺畅，普通电动门在启闭时易晃动，运行继续且发出磨擦噪音，导致交接管折断。 电动伸缩门的离心式离合器，在停电时只需将精致的钥匙从专用离合孔插入，轻松旋转90度角，即转为手动运行。大功率动力驱动系统，电机蜗轮采用KK合金材料。具有强韧性，高强耐摩性，适用性，机械摩擦损耗小，机械传动效率高。电动伸缩门高性能耐高温、抗寒线，所有的电线我们采用高新性能材料表面耐寒抗养化，炎热的夏天在90℃时不受影响能正常使用。在寒冷的冬天零下50℃时仍然正常使用。
The intelligent infrared probe anti-collision device of the electric retractable door can automatically return to operation when encountering people or foreign matters of 30-50cm, so as to ensure the safety of vehicles and pedestrians. The electric expansion door can be used with electronic soft start and mechanical buffer device. When it is opened and closed, the main engine does not shake and operates smoothly. The ordinary electric door is easy to shake when it is opened and closed, and the operation continues and generates friction noise, resulting in the fracture of the connecting pipe. The centrifugal clutch of the electric expansion door only needs to insert the delicate key from the special clutch hole when the power is cut off. It can easily rotate 90 degrees, that is to say, it can be turned into manual operation. High power drive system, motor worm gear made of KK alloy. It has strong toughness, high friction resistance, applicability, small mechanical friction loss and high mechanical transmission efficiency. The electric expansion door is high-performance high-temperature and cold resistant wire. All wires are made of high-tech materials, which are cold resistant and resistant to curing. In hot summer, they can be used normally without being affected. It is still used normally in cold winter at - 50 ℃.
