The moderate stage curtain is using tube Motor with huge power and hot-protection device, which could up, down and stop at random. It is noiseless and easy to adjust.The material of the tube is aluminum with high quality and intensity without distorting. The surface has done with anode oxidize, which is proven the surface from aging and resist on corrosion. One can choose the aluminum tube with diameter of 50mm, 65mm and 90mm according to the height and weight of blinds. It use tape roll support with the same inner diameter. In order to make sure the safe and reliance, the bracket is alloy steel, which is good at resisting on curving and cutting.

The large-scale stage curtain is using the special Motor with braking function, which is sure of the steady of the mechanism. Setting turbine gear box with double exceed axes. It can adjust the speed of elevating. The working system is using precise count method. It is together with motor. This mechanism have perfect motor time-lasting and protection of circuit and control function.
