Cause analysis and solution of tower crane blind area

Measures to solve blind area of tower crane

1. During the construction, if possible, try to increase the number of tower cranes. Multiple tower cranes are used to construct the same building in an all-round way, which can reduce the possibility of tower cranes forming a blind area.

If the number of tower cranes is limited, the construction of each tower crane with complementary cooperation should be carried out as far as possible, so that the whole building will be within the scope of tower crane construction with complementary cooperation, and the possibility of blind area formation may be reduced.

2, in the installation of the tower crane should be carried out on the construction site careful investigation, the length, width, height of the building survey clearly, but also to calculate the activities of the tower crane crane boom and the safe distance between the tower crane.

The surrounding building peripheral equipment. Then the tower crane is installed, and the tower crane should be installed in the best position for lifting. This will also reduce the possibility of the tower crane forming a blind spot.

2. For the blind area formed by the shielding of some tall buildings that have been constructed, the height of the tower crane should be increased to make the whole tower crane in the highest position

3. the tower crane can cover the entire construction operation surface as much as possible, so as to reduce the possibility of the blind area formed by the tower crane.

4. For the problem that two tower cranes are afraid to touch each other and form a blind area, the height difference between two tower cranes can be increased to solve the problem, and the original manufacturer can purchase an arm that can adjust the length to be fixed.

5, for those due to the interference of dangerous objects caused by the tower crane blind area, should be in the tower crane installation when the choice of the best position to avoid those dangerous objects.

6, the tower crane for regular maintenance, for those who have been aging or damaged tower crane parts, must be repaired before use, as long as there is abnormal phenomenon firmly not to use. Or eliminate it directly, so as not to affect the construction.

7. Master unified command signals. There must be tacit understanding between tower crane operators. Signal commanders use intercom to communicate with drivers.

Each tower crane has its own channel. The driver should order a person to order a machine, prohibit to adjust post without permission.

8. Strictly check the command and operation personnel of the tower crane. Those who do not meet the requirements shall not operate and command the tower crane.

The tower crane driver and the command shall be on duty with a license. The command shall use technical language and communication devices and other contact signals according to the regulations.

The operator shall operate according to the flags, gestures or whistles predetermined by the commander. If the command signal is not clear and may cause an accident, the operator should refuse to carry out and immediately notify the command personnel

But any signal sent by anyone to avoid an accident or eliminate danger should be heeded and decisive measures taken.

Third, summary

The blind area of tower crane is caused by many reasons, which are caused by the negligence of some links in the construction process or the installation of tower crane and the calculation of data.

So the construction process must be in the installation, survey and other links in line with the requirements, through the joint efforts of the relevant personnel, so that the organic combination of people, equipment and environment, so as to ensure that the formation of the tower crane blind area.
