(1) Construction Process:

Basic embedment preparation → Sectional sleeve connection of the pole → Inserting steel wire ropes and cables → Head installation → Hoisting → Adjusting the verticality of the pole → Power connection → Installing and adjusting the light panel → Installing lighting fixtures → Adjusting

(II) Construction Method:

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

1. Organizing foundation components:

Clear debris and trash from the concrete foundation surface, remove protective materials wrapped around the embedded bolt, check 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 the nuts can be freely tightened onto them.

2. Tube Socket Assembly

Prior to 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 done simultaneously with the assembly of the rod body. (See Figure 1)

Starting from the very bottom section of the socketed rod, proceed upwards, section by section.

Position the base section with 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 be off the ground, leaving sufficient space for the insertion of the upper section rod.

Mark the socket depth on the base section, the socket depth between each section shaft, varies with the diameter of the shaft, and this depth dimension can be found in the drawings.

Nuts are welded on both sides of the rod body for hanging and tightening the wire rope. When lifting, confirm the position to ensure that 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 end with the front end of the base section, and slowly slide it in. Try to fit it as deeply as possible, and also place wooden wedges 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.

Tighten the manual winch on both sides of the rod simultaneously until reaching the sleeve depth marker. If you encounter significant resistance during tightening, use a hammer to strike the sleeve section of the rod to create vibration, aiding in the snug fit of the rod. When striking, place a wooden board or other material as a cushion to prevent damaging the rod surface. (See Figure 2)

Following the above steps and methods, sequentially connect the other sections of the rod.

3. Wire Rope and Cable Lacing

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

4. Head Mounting:

Lift the front end of the rod, which has been fitted with sockets and through which the steel wire rope and cables have been inserted, using an object (with the electrical door of the rod facing upwards). The height of the lift should allow 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 onto the rod. 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 to ensure the clearance between the head sleeve and the rod body is consistent (i.e., align the axis of the head sleeve with the axis of the rod body). The purpose is to have the three sets of pulley shafts at the same horizontal plane after the rod is erected.

Pull three suspended steel wire ropes and cables towards the bottom of the pole, up to the level of the electrical door, ensuring the distance from the ground can be connected to the fixed points of the light panel. Temporarily tie them up with ropes on the pole to minimize interference during the hoisting process.

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

5. Hoisting:

After completing the aforementioned steps, please carefully inspect and verify to ensure no omissions and safety, then you may prepare for the hoisting operation.

Based on the conditions of the steel light poles at 35 meters, 15 meters, and 8 meters, select the crane and rigging equipment. During the lifting process, the site supervisor will coordinate to ensure a reliable and orderly road for the entire installation of the light poles.

The theodolite checks the perpendicularity with a level, allowing for an allowable deviation: 2H/1000 for the telescopic type, and 3H/1000 for the 10-meter lamp post, with a maximum height of 20 meters (H is the height of the lamp post, in millimeters).

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

5.1 The machine head must be positioned below the light pole head during the lifting and installation process.

5.2 The lifting point should be at two-thirds of the rod body.

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

5.4 The lifting point should be positioned to facilitate the placement of the light pole in the predetermined direction.

6. Light panel installation and adjustment:

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

Later, install lightning rods on the lamp disc.

7. Cable Wearing

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

At the front end of the rod or the cable entry hole of the light plate, wrap and secure the guide wire around the cable. Pull the guide wire, coordinating with the insertion of the cable, to thread the cable into the rod.

8. Lighting Installation:

Install lighting fixtures at the designated positions on the lighting panel, wire them, power them on, and conduct a 24-hour lighting test.
