(1) Construction Process:

Basic embedment preparation → Sectional jointing of rod → Inserting steel wire rope and cables → Head installation → Hoisting → Adjusting rod verticality → Power connection → Installation and adjustment of luminaire panel → Installing lighting fixtures → Adjustment

(II) Construction Method:

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

1. Organization of foundation embedment components:

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 that the nuts can be freely tightened.

2. Socketing of the rod body:

Prior to starting 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 done simultaneously with the sleeve assembly. (See Figure 1)

Start from the very bottom section of the rod body and proceed upwards, section by section.

Position the base section with flange near the foundation in the appropriate location (place the electrical maintenance door upwards), 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.

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

Nuts are welded on both sides of the rod body for hanging and tightening the cable. During 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 diameter end with the front end of the base section, and slowly slide it in. Insert 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.

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

Follow the aforementioned steps and methods, sequentially connect the other sections of the rod.

3. Wire rope and cable threading

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

4. Head Mounting:

Rise the front end of the rod, which has already been socketed and with wire ropes and cables inserted, using a support object (the electrical door of the rod facing upwards). The height of the support 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 into the rod body. The fork position with the cable pulley on the head should align with the electrical door in the same orientation. (See Figure 4)

Tighten the set bolts in sequence, adjusting the screw-in depth to ensure consistent spacing between the head sleeve and the rod body (aligning 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 upright.

Pull three suspended steel wire ropes and cables to the bottom of the rod, above the electrical door, so that the distance from the ground can be connected to the fixed point of the light panel. Temporarily tie them up on the rod with ropes to minimize interference during the hoisting operation.

Later, install the 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 reliability, then you may prepare for the hoisting operation.

Based on the individual conditions of the 35-meter, 15-meter, and 8-meter steel lamp posts, select the crane and lifting equipment. During the lifting process, the site supervisor will统一指挥 to ensure the entire process is conducted reliably and orderly on the road.

Theodolite and rule are used to check verticality, with allowable deviation: 2H/1000 for lift-and-slide types, and 3H/1000 for 10-meter poles, not exceeding 20 (H is the height of the pole, in mm).

Please note the following points for the hoisting of telescopic boom cranes:

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

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

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

5.4 The fixed lifting position should facilitate the placement of the lamp post in the predetermined direction.

6. Installation and Commissioning of Light Panels

Tighten the set screws onto the light fixture sleeve nut, lift the light fixture with a crane, and fit it onto the front end of the pole. Gradually tighten the set screws, adjusting the depth of insertion, to ensure the sleeve and pole have a consistent gap around their perimeters (i.e., align the sleeve axis with the pole axis).

Later, install lightning rods on the lamp plate.

7. Cable passing

Before threading 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 section on rod sleeve jointing), or after the rod is mounted on the base.

At the front end of the pole or the cable entry hole of the lamp plate, wrap and secure the guide wire around the cable. Pull the guide wire to assist in threading the cable into the pole body.

8. Lighting Installation:

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