Principle Introduction 

1.small and medium size electric stage lifting screen use SHIDAI strong power AC tubular motor, built-in overheating protection device, can landing and stopping at will, with the feature of quiet running and convenient adjustment. Reelpipe is made of high quality aluminum alloy, high strength and difficult deformation. The surface is treated by anodizing and dull polish, anti-aging, corrosion resistance, according to the lifting height or weight can choose diameter 50mm,70mm,80mm reelpipe. Outside of reepipe is ropewinder which inner diameter is same as reelpipe’s, Bracket is made of high strength alloy,hign anti-bending, to ensure the safety and reliability in installation and using.

2.Large electric stage lifting screen system adopts the motor with automatic function. device adopts special motor with automatic function to ensure the stability; equipped with gear, can adjust different lifting speed according to requirement; limit control adopt high-precision count method; this device has perfect time-delay and overcurrent protection function and can be customized when it overweight.

 

Control method

Machinery button switching control, infrared or wireless remote control, can connecting central control system.
