How to replace the steel wire rope for the old high pole lamp

Process of replacing traction auxiliary rope of high pole lamp panel

1、 Tool preparation sleeve Φ 14mm、 Φ 27mm, wrench Φ 14mm、 Φ 27mm, chisel, hammer, diagonal pliers, electrical tape, Φ 12 10mm steel wire rope binding heads.

2、 Material preparation: 6-strand hemp core hot-dip galvanized steel wire rope Φ The length of 10mm is 33m, and there are three. One 30m old cable (or 30m long rope).

3、 Rope changing procedure

1. Lower the high pole lamp panel to the bracket position, remove the fixed pressing plate of the main cable, and remove three old steel wire ropes from the wedge-shaped binding head on the lamp panel.

2. Braid the ends of the three removed old steel wire ropes with the new ropes respectively, and the butt joint shall be firm. The braiding joint shall not be too large. The braiding part shall be wrapped with electrical tape, and the braiding part shall be smooth and smooth, so as to pass through the pulley. In addition, the cable end of the lamp shall be tied with the old cable with a binding head to prevent the lamp cable from sliding into the lamp pole and falling down when the main wire rope is pulled in the next step.

3. Slowly pull the main wire rope from the inside of the rod to the outside, and let the braiding head of the new and old ropes slowly pass through the pulley until the wire rope reel in the rod is pulled out of the rod.

4. Based on the position facing the cable on the distribution reel, and referring to the installation position of the cable and the wire rope pulley on the top of the light pole, remove the end of the old rope on the distribution reel in turn in an anticlockwise direction and connect the other end of the new rope with the wire rope binding head in sequence. At this time, the end of the new rope and the end of the old rope at the lamp panel are paired, and the braiding head has just passed the rod top pulley; The other end is connected with the end tie of the old rope head at the branch reel under the rod to form a closed loop.

5. Pull a butted steel wire rope from the inside to the outside of the pole until the cross braiding point is pulled to the outside of the lamp pole, cut off the braiding head of the new and old steel wire ropes, and fix the new steel wire ropes on the distribution reel.

6. Repeat step 5 to fix the other two wire ropes.

7. Slowly pull down the three old steel wire ropes and cables outside the rod together. The main steel wire rope shall be pulled by a specially assigned person to prevent the steel wire rope or cable from falling out of the pulley due to too fast sliding speed under gravity. Pull the main wire rope back to the drum.

8. At this time, one end of the new wire rope has been fixed on the reel. The other end is tied to the old rope and pulled under the rod. Remove the old and new steel wire ropes and the binding heads of the paired cables,

9. According to the installation position of the cable and the wire rope pulley on the top of the lamp pole, fix the end of the new wire rope on the wedge-shaped binding head of the lamp panel. Next, fix the main cable.

10. Raise the lamp panel to see if it is 5cm high. If it is uneven, properly adjust the auxiliary ropes.

11. After the lamp panel is leveled, lift the lamp panel hook to complete the rope replacement.
