Due to the long service life, there are some safety hazards such as fatigue, corrosion and deformation of the equipment structure. If it exceeds the fixed number of years, it can continue to be used after passing the assessment by a qualified assessment agency. 2. Evaluation of Construction Elevator SC-type construction elevator with service life of more than 8 years (excluding 8 years) has serious wear and tear of transmission system, serious fatigue, deformation and corrosion of steel structure, and potential safety hazards; SS-type construction elevator with a service life of more than 5 years (excluding 5 years) has serious fatigue, deformation and corrosion of structural parts and serious wear of moving parts, which has potential safety hazards. If it exceeds the fixed number of years, it can continue to be used after passing the assessment by a qualified assessment agency. (2) According to the provisions of No.45 and No.600 of the Municipal Safety Supervision Station in 2007, tower cranes and elevators that have not reached the designed service life and have not been used for more than 10 years shall be inspected and evaluated once a year, and inspected and evaluated twice a year for more than 20 years. The specific requirements are as follows: 1. Before equipment installation, the equipment unit shall apply to the mechanical inspection agency; 2.
