Tower Crane Disassembly Management
2024-01-31
The disassembly and assembly of the tower crane is a prone stage of accidents. Safety accidents caused by improper disassembly and unqualified installation quality account for a large proportion. The disassembly and assembly of the tower crane must be carried out by a qualified disassembly and assembly unit, and the installation and disassembly must be carried out within the scope of the qualification. The disassembly and assembly personnel must undergo special business training, have certain disassembly and assembly experience, and hold a certificate to work. At the same time, they must have complete staff of various types of work, clear positions, perform their duties, and obey unified commands. In the process of commissioning, professional electrician skills Level and sense of responsibility are very important. Electricians need to hold an electrician certificate and a lifting work certificate. Through statistics on a large number of tower crane inspection data, we found that a disassembly unit in our city has installed 54 tower cranes, and 47 failed the first inspection. , The first inspection pass rate is only 13%, most of which are due to the poor installation technology of the installation electrician, the negligence of the disassembly unit, and the safety awareness still needs to be further improved. Therefore, we conducted a special management to strengthen business training for this unit, and achieved good results. In addition, because the disassembly and assembly costs in the disassembly and assembly market were not in accordance with the budgeted price, there was even a 400-500 yuan installation of a tower crane, which also led to an important reason for the decline in installation quality. Special disassembly and assembly plans must be prepared for disassembly and assembly. The plan must be reviewed and signed by the technical person in charge of the installation unit, and assigned to the guard area and cordon where the disassembly and assembly unit participates in the disassembly and assembly. The operation is required by the procedures and instructions. When the wind exceeds level 4, disassembly and assembly must be stopped, and the tower crane should stop lifting operations when the wind exceeds level 6. Special circumstances do require adequate lighting for night operations, and those who do require night operations must fully negotiate and reach consensus with the crane driver on the procedures and precautions for disassembly and assembly.
