2. Then, insert the lower part of the diagonal bracket into four corners on the outside of the base, each corner preferably has two or more.
3. Fix the boring head on the base with screws. Here, be sure to pay attention to the rotating direction of the counter head. After fixing, put a square sleeve on the counter head.
4. Next is the beam part. First, connect the beam on the ground, and then connect the two ends of the beam with the two square sleeves on both sides, so that the beam part is assembled on the ground.
5. Connect the column truss horizontally, and then screw one end on the counter head and the other end on the cross arm. At the same time, connect the suspension crane with the cross arm. The crane is used to hang the beam truss below.
6, column truss stand up slowly, one more person to operate, be careful not to push too hard, and then fix the screws on the head.
7. After the column is completed, use the hook under the hoist to hook the beam below through the sling, and several people slowly pull the hoist to pull the beam to the left and right position of the person's head.
8. Install lighting, audio and other equipment required for activities on the beam. Then drag the suspended hoist to a predetermined height to stop.
9. Fasten one end of the diagonal brace to the column and the other end to the cross brace of the base, thus completing the gantry.
