A, tower down

1. Using the hydraulic jacking system of tower crane, remove the standard section from the sui node to the attached frame and dismantle the attached frame.

2. Continuously descend the tower to the required height and descend the standard section. Lower the tower crane 14 to the lowest position, and the distance between the bottom of the arm and the ground is m.

B. Tower crane removal

1, remove part of the balance weight piece tons.

2. Remove the boom, remove the height meters, and lift the boom as a whole.

3. Remove the remaining balance weight in tons.

4. Remove the balance arm, remove the height meter, lift the balance arm as a whole, loosen the pin shaft connected with the rotary tower body, and unload it to the ground.

5. Remove the top of the tower and the ladder and platform connected to the rotary tower.

6. Remove rotating parts, upper and lower supports, platform, slewing mechanism, driver's cab, slewing tower, etc.

7. Remove the climbing jacket.

8. Remove remaining standard section, foundation section and strengthening section.

C. After counting and registering the quantity of each component removed from the tower crane, transport it away from the construction site by heavy truck in time.

1. At the beginning, the hydraulic jacking system of tower crane was used to climb backward and descend to an appropriate position, and the distance between the bottom of the boom and the top floor was m.

2. In the position of the axis of the top floor, install and lift the steel tower, install the temporary mast, and disassemble the components above the top section in the reverse process according to the sequence when the tower crane is installed.

3. Lift the removed lifting boom, balance boom and other components to the ground after the disintegration of the top floor according to the carrying capacity of the temporary lifting mast.

4. Use temporary mast to lift out the standard section in the ladder well, bearing section, ladder climbing, bearing beam, and lower to the ground.

5. Remove and install the steel tower, temporary mast and lower to the ground.

6. After the tower crane is dismantled, the quantity is counted and registered, and then transported from the site by truck.

7. In order to make the floor of the building able to support and lift the steel tower, the pressure of the temporary mast downward and the weight of each component removed, the concrete slab of the floor shall be strengthened and set according to the requirements of the drawing.
