Check whether the tower crane foundation is equipped with drainage ditches or drainage equipment to ensure effective drainage; Whether the screw, nut, washer, etc. of the tower crane foundation and standard section of the tower crane are complete and connected firmly, and whether the diagonal brace is fixed by connecting pin shaft and cotter pin in strict accordance with the requirements; Is the rainproof measures for the tower crane distribution box reliable to ensure that electrical components are not exposed to rain; Whether the various limit and safety devices of the tower crane are sensitive and reliable, and whether the lightning protection grounding and protective zero connection devices meet the requirements; The attachment device used for the installation of tower cranes must comply with the product manual and relevant technical requirements, ensuring that the material, embedment, and installation meet safety requirements, and ensure that the connection is tight and the spacing meets the requirements. There are no unauthorized production or use of attachment devices. It is necessary to strictly manage the safety process, inspection and testing, safety technology, safe use, joint acceptance and monthly inspection, and installation and dismantling operations of tower cranes.
