Tower Crane Knowledge sharing：

Settlement, verticality measurement and deviation correction of tower crane

1. Settlement and perpendicularity measurement of tower crane shall be carried out regularly. Observation of tower crane settlement is usually done every half a month. The verticality shall be measured once every half a month when the tower crane is within the independent height.

2, when the uneven subsidence of the tower crane, vertical when more than 1/1000 of the height of the deviation, deviation correction should be made for tower crane before the attached to the wall is not set, the minimum section and the tower crane footing bolt padded between steel correction, the correction process.

With high tonnage of one thousand tons bumps up the tower and to ensure safety, the tower with big cable, cable, all around and footing bolt can not be removed, can only loose bolt nut, according to the specific length padded the thickness of the sheet steel.

Test run and acceptance of tower crane after repeated use and installation

Tower crane test and acceptance can be divided into three situations: factory, overhaul and re-use after installation. Here is mainly about: tower crane after repeated use installation test and acceptance. Including the following parts

(1) technical inspection

Check the solidity of the tower crane, the contact between the pulley and the wire rope, the electrical circuit, the safety device and the installation accuracy of the tower crane. In the case of no load, the tower and the ground vertical deviation shall not exceed three thousandths.

(2) no-load test

According to the lifting, turning, amplitude changing and walking mechanism, the action test is carried out respectively, and the joint action test of lifting, walking and turning is carried out. During the test, the sensitivity of each limit device was tested by colliding with it.

(3) rated load test

At the minimum working range of the boom, lift the rated maximum lifting weight, the weight is 20cm from the ground, keep the distance from the ground for ten minutes (at this time, the torque limiter should send out an alarm signal). After passing the test, carry out lifting, walking, turning action test and joint action test in the maximum, minimum and intermediate working range respectively.

During the above test, the theodolite should be used to observe the deformation and recovery of the tower crane in two directions, observe whether there is any abnormal phenomenon, temperature rise, oil leakage, paint peeling and other conditions during the test, record and measure, and finally confirm that it is qualified and can be put into operation.

Participants in the test and acceptance and test results should be recorded in detail and truthfully, and signed by the relevant personnel to confirm that they meet the requirements.
