Enterprises should attach importance to the safety management of the installation and disassembly process of high-rise tower cranes

Enterprises should attach importance to the safety management of the installation and disassembly process of high-rise tower cranes and strengthen the safety technical management of the installation and disassembly of high-rise tower cranes.

1. Units engaged in tower crane installation and disassembly at the construction site must obtain professional contractor qualification. Disassembly and assembly operation personnel must be trained by professional safety technology, the implementation of the post certificate.

2. Establish the second-level approval system for the installation and disassembly of high-rise tower cranes. Before the installation and disassembly of the tower crane, the installation and disassembly schemes and specific safety technical measures must be formulated according to the environment and conditions of the construction site.

The mechanical performance of the tower crane and the characteristics of auxiliary hoisting equipment. The installation and disassembly schemes shall be examined and approved by the technical person in charge of the professional construction  unit and the general contractor.

1. According to the approved construction plan of hoisting and dismantling of high-rise tower. The foundation of high-rise tower crane should be inspected before integral installation

Before the installation and disassembly, the signature and disclosure of targeted safety technology must be made, and the division of responsibility and unified command should be carried out according to the operating procedures.

In the disassembly and assembly operation, each working procedure shall be under the unified command of a designated person, a designated post, and a designated person. Disassembly and assembly operations should be set up warning area, and set up special monitoring.
