5, the standard section, the top lifting frame, the rotary platform installation should check whether the standard section model is correct, the top lifting frame and the standard section alignment meet the requirements, the introduction of the right direction of the car, whether the connection bolt is solid and reliable, bolt pre-tightening force meets the requirements.
6, after the installation of the cab, tower cap device should review whether the connection bolts are firm and reliable, whether the pre-tightening force is in accordance with the request, the backpoint of the undercarriage track contact, the relative value of the transverse deviation is not greater than 1/1000 of the gauge design size,

The absolute longitudinal deviation is not greater than 1/1000 of the gauge design size, and the vertical deviation of the(diagonal) tower body is not greater than 3/1000.

7, after the suspension wall, balance wall installation, should check whether the connection parts are reliable, connection shaft should not be tamper, fastening meets technical requirements. Perimeter, complete installation, pull rod or cable installation correct, average force, fastening meet technical requirements, balance iron installation correct and reliable.
After the above installation is completed, the lifting, amplitude, turning, and walking mechanisms shall be tested.

The operation of each working organization shall be balanced and loud, sensitive, reliable braking, and experimental in response to various safety maintenance and installation. Its actions should be sensitive and reliable.
9, so after the installation of the device, the upgrade test and the test of the operation of the tower crane.
