(1) Construction Process:

Sorting of basic embedded parts → Sectional sleeve connection of pole body → Inserting steel wire rope and cables → Installation of head → Hoisting → Adjusting verticality of pole body → Power connection → Installation and adjustment of light panel → Installation of lighting fixtures → Adjustment

(II) Construction Method:

The winch and electrical panel of the telescopic pole are pre-installed within the pole before shipment, and the hook mechanism and head are assembled as a complete unit. The entire system has been assembled and debugged in the factory. The goods delivered to the site are divided into pole sections, head assembly, hook mechanism assembly, rain cover, light panel, and accessories (including wire ropes, cables, lightning rods, light panel brackets, electric tools, etc.).

1. Organization of foundation embedment parts:

Clear debris and trash from the concrete foundation surface, remove protective materials wrapped around the embedded bolt, recheck the spacing dimensions between all bolts (including diagonal dimensions), and confirm that the bolt positions match the dimensions shown in the drawings. Visually inspect the bolt threads for damage; if necessary, repair the threads to ensure nuts can be freely tightened onto them.

2. Socketing of the rod body:

Prior to beginning the sleeve assembly, a thin steel wire or wire longer than the rod height should be threaded through the electrical door into the rod body. This will serve as a guide for threading wire ropes and cables later on. The threading of the wire or wire should be performed simultaneously with the sleeve assembly process. (See Figure 1)

Start from the very bottom section of the sleeve, working upwards section by section.

Position the base section with the flange near the foundation in the appropriate location (place the electrical maintenance door upward), ensuring the flange is on the ground. Use wooden wedges to elevate the front end of the base section about 1.5 meters from the front, allowing the front end to clear the ground, leaving sufficient space for the insertion of the upper section rod sleeve.

The socket depth on the base section is marked, as well as the socket depth between each section rod, which varies due to the diameter of the rods. This depth dimension can be found in the drawings.

Nuts are welded on both sides of the rod body for securing the steel wire rope that pulls the sleeve tight. When lifting, confirm the position to ensure the nuts of the upper and lower sections are aligned in a straight line.

Hoist the rod body from the previous section with a crane, aligning the larger diameter end with the front end of the base section, and slowly slide it in. Aim to fit it as deeply as possible, and also place wooden padding blocks at the front end of this section.

Tighten bolts on the nuts on both sides of the upper and lower rod bodies, and securely install the tensioned wire rope and hand winch as shown in the following illustration on both sides of the rod bodies.

Simultaneously tighten the manual winch on both sides of the rod until the sleeve depth marking is reached. If resistance is felt during tightening, use a hammer to strike the sleeve section of the rod to create vibration, assisting in securing the rod. When striking, use a board or other material as a cushion to prevent damage to the rod surface. (See Figure 2)

Follow the above steps and methods to sequentially connect the other sections of the rod.

3. Wire Rope and Cable Insertion

Once the rod sleeve is assembled, connect the rigging coupler to the winch's main wire rope, then secure it to the guide wire left in the rod from within the electrical door. Release the winch to allow the main wire rope to unwind from the drum (refer to the external electric winch lifting pole operation manual if using electric control). Simultaneously, pull the guide wire at the other end of the rod to pull the rigging coupler out through the small end of the rod. Move the head to an appropriate position at the front end of the rod, thread the ends of the three suspended wire ropes without loops and the cable through the head sleeve, through the pulley groove, and out of the head opening. Then, connect the other end of the suspended wire rope with loops to the rigging coupler (the cable connection method is shown in the figure). Operate the winch to retract the main wire rope, causing the rigging coupler to retract and enter the rod (about 100cm into the rod). (See Figure 3)

4. Head Installation:

Lift the front end of the rod with completed sockets and inserted wire ropes and cables using an object (the electrical door of the rod facing upwards), ensuring the height allows the installed head to clear the ground.

Tighten the set screw onto the nut of the head sleeve, lift the head with a crane, and insert it into the rod body. The fork position with the cable pulley on the head should align with the electrical door's orientation. (See Figure 4)

Tighten the set bolts in sequence, adjusting the screw-in depth of the bolts to maintain consistent clearance between the head sleeve and the rod body periphery (i.e., align the axis of the head sleeve with the axis of the rod body). The purpose is to ensure that the three sets of pulley shafts are on the same horizontal plane after the rod is erected.

Pull three suspended steel wire ropes and cables towards the bottom of the pole to the height above the electrical door, ensuring the distance from the ground can connect with the fixed points of the light panel. Temporarily tie them to the pole with ropes to minimize interference during hoisting.

Later, install a rain cover, lightning rod, and connect the jumper wire at the top.

5. Hoisting

After completing the above steps, please carefully inspect and verify to ensure there are no omissions and everything is secure, then you can prepare for the lifting operation.

Based on the conditions of the steel lamp posts at 35 meters, 15 meters, and 8 meters respectively, select the crane and lifting equipment. During the lifting process, the site supervisor will provide unified command to ensure the reliable and orderly progress of the lamp post installation on the road.

Theodolites and level gauges are used to check verticality, allowing deviations: 2H/1000 for elevating types, 3H/1000 for 10-meter light poles and not exceeding 20 (H is the height of the light pole, in mm).

Please note the following points for the hoisting of telescopic tall poles:

5.1 The head of the machine should be positioned below the top of the lamp post during the lifting and installation process.

5.2 The lifting point should be at two-thirds of the rod's length.

5.3 The lifting equipment's load must meet the weight of the rod body.

5.4 The fixed position for lifting should facilitate the placement of the light pole in the predetermined orientation.

6. Installation and tuning of light panels:

Tighten the set screw onto the lamp plate sleeve nut, hoist the lamp plate with a crane, and insert it onto the front end of the pole. Gradually tighten the set screws, adjusting the depth of screw insertion, to ensure the sleeve gap around the pole body remains consistent (i.e., align the sleeve axis with the pole axis).

Later, install lightning rods on the lamp panel.

7. Cable Traversing

Prior to stringing the cables, a guiding steel or iron wire should be inserted first. This step can be pre-completed during the rod sleeve jointing (refer to the rod sleeve jointing section) or after the base is mounted onto the rod.

At the front end of the pole or the cable entry hole of the lamp disk, wrap and secure the guide wire around the cable. Pull the guide wire, coordinating with the insertion of the cable, to thread the cable through the pole body.

8. Lighting Installation:

Install lighting fixtures at the predetermined location on the luminaire panel, wire them up, supply power, and conduct a 24-hour lighting test.
