How do you build a truss stage?

First place the four bases in approximate positions on the ground, and adjust the lower legs to make them in a horizontal plane;

Insert the underside of the diagonal support on the outside of the base at the four corners, each Insert 2 pieces on the corners, a total of 8 pieces;

Fix the reverse head on the base with screws, pay attention to the direction of rotation of the reverse head to be the same as marked in the figure;

Put a square sleeve on the reverse head;

Handle Connect the beams on the ground;

Connect the two ends of the beams to the two square sleeves on both sides respectively. At this time, the beams are assembled on the ground;

Connect the column truss on the ground, and then Screw one end to the reverse head, and the other end to the cross arm. At the same time, the hanging gourd and the cross arm are connected. The function of the gourd is to lift the beam truss below;

Many people work together to erect the column truss slowly. Get up, be careful not to push the column with too much force, and then fix the screws on the reverse head;

After the column is erected, hook the hook under the hanging gourd to the beam below through the sling;

4 people slowly together Pull the hanging gourd to pull the beam to the left and right positions of the person's head;

Install lighting and sound equipment on the beam;

 4 people pull the hanging gourd to a predetermined height to stop;

Support the diagonally Tighten one end to the column, and the other end to the horizontal support of the base, so that the aluminum alloy frame is completed.
