At present, the accident occurred in the tower crane assembly and disassembly process has been accounted for a larger part of the crane accident, which explains the growing popularity of high-rise buildings at the moment, the tall tower to complete its construction and dismantling, the risk of which bears indeed It is not to be underestimated. How to ensure the safety of tower crane assembly and disassembly of employees has become a big crane problems to be solved.

 

Tower cranes (also known as tower crane) functions of each part can be divided into: basic, tower, lifting, rotating, lifting, balancing arm, boom, lifting car, tower, cab, amplitude, etc. section. Among them, the tower crane assembly and disassembly accident occurred mainly in the assembly and disassembly of the tower, which is the raised portions and the lifting boom (lifting weights in general is the force member) part, it is carrying out the work of the two parts during assembly and disassembly We should all pay attention to safety outside.

 

Overall, when you do the tower crane assembly and disassembly work can depart from several aspects:

 

First, carefully handled disassembly declaration procedures. Before dismantling the tower crane, the use of units should be required to declare the relevant government departments, provide the required disclosure of information by the government authorities for examination and approval before disassembling.

 

Second, choose the appropriate qualifications disassembly team. Use unit tower crane dismantling work, you must select team with appropriate professional qualifications undertaken shall not be entrusted without obtaining appropriate professional qualifications of dismantling the tower crane dismantling work units.

 

Third, the real preparation dismantling plan, safety and technical disclosure. Performed before dismantling the tower crane dismantling unit must prepare a detailed and practical dismantling construction program, to prepare the basis, project profiles, foundation construction, tower crane installation, safety measures and other program content is written and signed approval of the audit is complete, After the approval of the Executive and report to the requester. Tower crane dismantling job before working units should carefully to all safety and technical tests, construction workers, and to apply for technical tests confirm safety procedures.

 

Fourth, in strict accordance disassembly disassembly procedures. Disassembling operation process must be based on the specific requirements of different types and specifications of the tower crane, in strict accordance with dismantling program operations, to avoid causing accidents.

 

Fifth, good selection of removable devices. Before dismantling the tower crane, lifting equipment should be selected according to the construction site and the maximum weight of the structure, installation height.

 

In addition, good dismantling site security measures, timely acceptance procedures and Zhunyongzheng also ensure tower crane assembly and disassembly security, particularly important way of second-hand crane, crane rental equipment removably secure.
