Cause analysis and solution of tower crane blind area

With the constant change of building structure and height, tower crane often appears certain blind area in application, which reduces the construction efficiency and increases the construction cost and risk.

This paper enumerates practical cases of the phenomenon of tower crane blind area, analyzes the reasons for the formation of tower crane blind area, and puts forward some measures to solve the formation of tower crane blind area. In order to improve the construction efficiency, reduce the construction cost causes of formation of blind area of tower crane

1. The number of tower cranes is limited, and several tower cranes do not complement each other in the construction process.

 For example, the construction tasks of tower 4 and tower 6 in the above example are mainly undertaken by tower D and tower F. Unlike tower 5, which has multiple tower cranes for construction, it does not receive complementary support from other tower cranes.

Therefore, certain tower crane blind areas are bound to occur in these two buildings.

2. In the above example, under the premise of satisfying the work space for erecting and removing towers and covering all the construction work surfaces as far as possible

In order to ensure that tower D and tower F can avoid the 3# and 8# buildings that have been completed in the process of lifting boom rotation, due to the shielding of these two buildings, a fixed tower crane blind area should be generated in tower 4 and tower 6.

Therefore, the completed construction also has a certain impact on the formation of blind area of tower crane.

3. In the process of tower crane installation, the installers do not have a clear survey of the construction site, and the installation position of the tower tower is not the best position for tower crane installation. In the above example, the installation of tower D and tower F is not the best position for tower crane installation.

4. installation personnel length of height, width, the building of the building, and surrounding environment of understanding is not clear, and during the installation process ignores the construction completion of buildings will also affect the normal work of the tower crane.

Some tall buildings to the attention of the tower crane operator cover can also cause cranes form blind spots. For example, in the above example, buildings 3 and 8. which have been completed, have an impact on tower D and tower F, so these two tower cranes have a blind spot during the construction of buildings 4 and

5. tower crane and tower crane jib range and the surrounding buildings or building safe distance between peripheral equipment also have impact of tower crane blind area.

In the case because of tata jib end distance has to ensure that the D construction of 3 # building external wall to ensure the safe distance of 2 m, F tata jib end distance is the construction of 8 # building external wall to ensure the safe distance of 2 m, and a blind area are formed when the two sets of tower crane construction.

6. The causes of tower cranes themselves will also have an impact on the formation of the blind area. Some tower cranes can not reach the required turning radius due to their own reasons, such as aging of tower cranes and abrasion of steel cables.

For normal tower cranes, there will be no blind area in the construction process, but there will be blind area due to its own reasons.

7. Cooperation between operators will also affect the formation of the blind area. Whether there is a tacit understanding between the signal commander and the tower crane operator.

Whether the signals can be understood each other, these factors will also have a great impact on the construction, but also on the formation of the blind area.

8. The command and operation personnel of the tower crane also have some influence on the blind spot of the tower crane.

For example, the operator's physical defects (such as myopia, color blindness, hearing impairment, etc.) will have a certain impact on the operation of the tower crane, but also on the formation of blind areas.
