Aluminium stage truss method:
1. Place the base in a rough position on the ground first;
2. Insert the part under the diagonal support on the outside of each base;
3. Fix the reverse head on the base with screws;
4. Put a square sleeve on the reverse head;
5. Connect the beams with screws;
6. Butt-connect the two ends of the beam with the two square sleeves on both sides. At this time, the beam part is assembled on the ground;
7. Connect the column truss while lying flat, then screw one end to the reverse head, and the other end to the cross arm. At the same time, the hoist and the cross arm are connected. The function of the hoist is to lift the lower beam truss; (You can also install the gourd after the column is erected.)
8. A group of people slowly erect the column truss together, taking care not to push the column with too much force, and then fix the screws on the reverse head;
9. After the upright is erected, hook the hook under the hanging gourd to the beam underneath through the sling;
10. The 4 people slowly pull the hanging gourd together to pull the beam to the left and right positions of the person's head;
11. Install lighting and sound equipment on the beam;
12. Four people pull the hanging gourd together to a predetermined height to stop;
13. Tighten one end of the oblique support to the column, and the other end to the horizontal support of the base, so that the gantry is built.
