What should be paid attention to when using movable stage truss?

The distance between the cross arm and the cross beam should not be too large. Try to raise the height of the stage lighting frame to the nearest place to the cross arm, and try to make use of the height of the column, otherwise the cross beam will shake easily and it will be easy for workers to arrange the lighting and sound. For the high stage lighting frame, some safety measures should be taken, such as adding cables, poles, ceilings and other fixing measures. Otherwise, it is easy to collapse. Do not add tarpaulins and grid cloth above the truss, which will increase the lateral force of the stage lighting frame and increase the lateral area of the stage lighting frame, which may cause accidents due to the increase of wind power. Please don't use the stage light frame carefully in bad weather. Bad weather such as typhoon and rainstorm may cause accidents, so you should be fully prepared. If this happens, the outdoor stage lighting frame should be removed or lowered to a safe point in time. Precautions There are many ways to build stage lighting fixtures, but we should pay attention to these safety measures to prevent the occurrence of stage safety accidents. For the smooth progress of stage activities, it is very necessary to let everyone know the construction methods of these stage lamps.
