Installation procedure, installation test and commissioning, application for inspection and application for permit

In this paper, provide the tower crane installation steps, tower crane installation testing and debugging, tower crane inspection and application for permit and other content.

A. installation steps of tower crane

Installation order, briefly route identification: embedded bolts to install base section, install the tower section and set to install rotary assembly, install rotary tower and the driver room to install the balance arm, hoisting balance weight to install jib, hoisting the remaining balance weight to install hook to cable installation, commissioning, jack-up, attached to the attached position.

1. Check the basic level with the level meter, and the level shall not exceed 1/1000; The strength grade of concrete shall not be lower than.

2. Install the tower body bottom type on the concrete foundation, use the theodolite to calibrate the center line of the tower body perpendicular to the horizontal plane.

Only two pieces of open spacer between the base planes are allowed to adjust the tower body, and the vertical degree of the tower body should be less than 3/1000.

3. Install foundation section, strengthening section and standard section on embedded bolts and embedded seats. Install the cross, compression weight and four struts.

4. the ground will be set on the shelf platform assembly, packed sets of escalators, standing on the platform to install hydraulic jack-up device that will climb set lift, set in the tower foundation section and section two standard.

Should keep climbing set opening parallel to the direction of building, will be set on the shelf jack-up beam resting on the bottom step on the basis of section, make a sense of oil cylinder alignment step side set into the tower.

5. Install upper and lower supports and rotary gear ring as one component on the ground, install the introduction guide rail and lift the rotary part.

6. Hoist the transition section of the tower body, check the electrical equipment in the driver's cab on the ground, and hoist the cab.

7. Fix the last pull rod of the balancing arm and the pull plate of the lifting boom on the tower cap on the ground and lift the tower cap.

8. Assemble the balance arm, lifting mechanism, balance boom and pull rod on the ground.

Lift the balance arm as a whole and make it connect with the hinge points of the tower body, connect and install the connecting pin and the balance arm pull rod.

9. According to the requirements of the crane manufacturer's installation manual, lift and load the balancing block first, and fasten t and t on the balancing arm.

10. Assemble the lifting boom, pull rod, lifting trolley and lifting mechanism on the ground. Hoist the boom as a whole, connect it with the hinge points of the tower body, and install the boom pull rod.

11. Lift the remaining balance weight t block and t block.

12. Install the hook through the hoisting wire rope, install the cable, connect the power supply, and the tower crane is tested to meet the requirements.

13, tower crane jacking height, according to the tower crane manufacturers operating instructions or mechanical equipment safety technical operation procedures to write the steps.

According to the main structure construction required height, continuous jacking or attachment after jacking, operation to the required height. First continuous jacking operation to m, using reinforcement section, standard section.

The second consecutive jacking operation to the height of meters, using the reinforcement section, standard section. The third consecutive jacking operation to the height of meters, using the strengthening section, standard section.

14. For the structure of connection, the high-strength bolt or pin shaft manufactured by the original factory shall be used. If the bolt is made of self-13 system, it shall be proved by qualified experiment, otherwise it shall not be used.

15. When connecting bolts, use special torque wrench and tighten them according to assembly technical requirements.

B. Tower crane installation, testing and debugging

1. check the tower crane circuit wiring is correct.

2. Comprehensively check whether the connection parts of the whole machine are correct and firm.

3. When there is no wind, the axis of the tower is perpendicular to the horizontal plane of the foundation, and the allowable difference is less than 3/1000. 4, the tower grounding resistance less than Ω lightning detection, meets the requirements.

5. Tower crane test run, check whether the lifting of main engine, tower crane rotation and trolley walking are normal.

6. Debug all safety devices of the tower crane, including torque, ultra high and amplitude limiter, to be sensitive, accurate, safe and reliable; The hoisting hook and the drum of the winch are provided with safety device; The venerable master has a shaving guard.

C. Apply for inspection of tower crane and apply for permit

After the tower crane is installed and tested, it shall be initially inspected by the relevant departments of the company, and then submitted to the special equipment department of provincial and municipal bureau of quality
