L46A1 Mast Section Strengthen the tower crane installation, disassembly management, collapse accident prevention measures summary
the key to ensure the safety of the tower crane is to manage the installation and disassembly of the tower crane. From the analysis of the causes of the Tower Crane collapse accident, it is concluded that the tower crane collapse accident is mainly caused by the installation, disassembly, use and the quality problems of the tower crane itself Therefore, the measures to prevent the tower crane collapse accident mainly aim at the three reasons to strengthen the management of tower crane installation and disassembly. Carefully go through the procedure of Disassembly and assembly declaration: Before the Tower Crane is installed and disassembled, the user unit shall, in accordance with the relevant provisions, make a declaration to the competent government department concerned, and provide the required declaration materials, only after examination and approval by the competent government department can the installation and disassembly be carried out.

Select the installation and disassembly team with corresponding qualification: The unit using the tower crane for installation and disassembly must select the team with the corresponding professional qualification to undertake, shall not entrust the relevant professional installation, demolition qualification units for tower crane installation, demolition work. Carefully draw up the installation and disassembly plan, and give a full account of the safety technology: Before the tower crane is installed and disassembled, the disassembly and assembly unit must draw up a detailed and feasible disassembly and assembly construction plan, to prepare the basis, project profile, basic construction, tower crane installation, safety measures and other contents written into the plan and approved by the full signing, and reported to the entrustment unit for approval after implementation. Before the installation and dismantling of the tower crane, the disassembling and assembling unit shall earnestly provide all construction personnel with the technical disclosure of the tower crane safety, and go through the procedure of the technical disclosure confirmation of the safety. Strictly follow the disassembly procedure. In the course of disassembly and assembly, we must strictly follow the disassembly procedure to avoid accidents according to the specific requirements of different tower crane models. Do a good job in the selection of disassembly and assembly equipment. Before the tower crane is disassembled and installed, the corresponding lifting equipment should be selected according to the construction site conditions, the maximum weight of structural components, the installation height and so on. Do a good job tower crane installation, demolition site safety protection measures: set up warning signs, set up safety signs, equipped with safety staff responsible for site safety. Timely go through acceptance procedures and permits. On-site inspection: After the erection of the tower crane is completed, the competent government department must be requested to conduct on-site inspection and issue the permit. Keep a record of the disassembly and assembly. The users shall arrange and record the technical data of the Tower Crane's disassembly and assembly into the equipment management files according to the regulations. Strengthening the use management of Tower Crane: Use Management is an important part of equipment management, is to ensure that in-service mechanical equipment is always in good technical condition, to ensure the safe operation of equipment.
