How to build an aluminum alloy truss

The steps for building an aluminum alloy truss are generally divided into 13 steps. The specific steps are as follows:

1. Put the four bases on the ground and adjust the lower legs so that they are on a horizontal surface.

2. Insert the part under the diagonal support on the outside of the base at the four corners, insert 2 at each corner, a total of 8;

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

4. Put a square cover on the reverse head;

5. Connect the beams on the ground;

6. Connect the two ends of the beam to the two square sleeves on both sides, at this time, the beam parts are assembled on the ground;

7. Connect the column truss flatly, then screw one end to the opposite head, and the other end to the cross arm, and at the same time link the hoist and cross arm. The function of the hoist is to lift the lower beam truss ;

8. Several people slowly erect the column truss together, taking care not to push the column too hard, and then fix the screws on the reverse head;

9. After the column is erected, hook the hook under the hoist through the strap to the lower beam;

10 or 4 people slowly pull the hanging hoist together to pull the beam to the left and right positions of the person;

11. Install lighting and sound equipment on the beam;

12,4 people pull the hoist together to a predetermined height to stop;

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