Truss system <br>truss system from the top of the bar truss, truss annular, internal stripe trusses. Top Top truss and vertical lift bar connected to the system, lifting the bottom of the lower annular truss, which must meet the length venues hanging point range and the top of the steel beam width requirements Astromesh; Astromesh top surface of the guide rail is provided, at its inner annular truss bar move along the rails the internal space range; slightly less than the internal annular truss truss bar, arranged at the top rail and the slider is connected to the annular truss rail top surface, a bottom rail disposed in the longitudinal direction (i.e., inner annular top and bottom truss is provided perpendicular to each other double rail), bottom rail is connected to the imaging system, the imaging system may be moved along the bottom rail, but also the inner strip along the top rail moves along the truss.

Truss system<br>The truss system consists of the top bar truss, the ring truss, and the inner bar truss. The top bar truss is connected to the vertical lift system, the bottom is hoisted lower ring truss, the length of which should meet the requirements of the steel beam suspension point range and the width of the ring truss at the top of the venue; The top configuration rail slider is connected to the ring truss top guide, the bottom is set in its length direction (i.e. the inner ring truss top and bottom are set with vertical double rail sits perpendicular to each other), the bottom rail is connected to the camera system, the camera system can move along the bottom rail, but also along with the internal bar truss along the top rail.

truss system<br>The truss system consists of top strip truss, ring truss and inner strip truss. The top of the top strip truss is connected with the vertical lifting system, and the bottom is used to lift the lower ring truss, whose length shall meet the requirements of the lifting point range of the steel beam at the top of the venue and the width of the ring truss; the top surface of the ring truss is provided with guide rails, and the inner strip truss can move along the guide rails within the scope of its ring internal space; the inner strip truss is slightly lower than the ring truss, and the top is equipped with guide rail sliders and ring truss The top guide rail of the frame is connected, and the bottom guide rail is set in its length direction (i.e. the top and bottom of the inner ring truss are provided with double-layer guide rails which are perpendicular to each other). The bottom guide rail is connected with the camera system, and the camera system can move along the bottom guide rail as well as the top guide rail together with the inner strip truss.
