      Performance and technical difficulties of the next volume electric curtain:
      ?Published: 2012.11.01 ??Views:1121Secondary
      Advantages: large engineering electric curtain curtain is the most difficult to resolve the formation and dynamical systems, the next roll lifting device is derived from the structure of the vertical elevator and loading and unloading crane principle, take advantage of the next big reel gravity curtain always remain flat, fourthe above electric gear motor synchronization to work, very smooth and quiet running up and down.
      Technical Difficulties: a meter long two-ton giant electric screen must have a large platform installation and commissioning; four large motors must ensure synchronous operation, wire sling and the power cord and the curtain on volume downstream must harmonization which is the biggest problem; fitter technologically adept, carefully, particularly in the paste curtain slightest error will expand several times in the screen surface rendering.
