4. Accident occurrence and emergency rescue
(1) On November 22, 2025, the accident occurred
in the project of 0308-02 and 0314-05 plots of BSP0-0103 units of Gucun large residential community in Baoshan District. Liu Moufa, Liu Moumeng and three workers in the carpentry class of Cailifeng Company started work at 6 o'clock. 56, three workers dismantled and installed aluminium formwork on the steel platform in the elevator shaft on the east side of the 14th floor of Building 17. Before the accident, two lifting wire ropes were hung under the hook of No.17 tower crane trolley, and a U-shaped shackle was hung on the wire rope respectively. Liu Mou-meng stood at the northeast corner of the steel platform and used tools to pry an aluminum template on the wall of the shaft and hook it. Xiang Mou-mou and Liu Mou-fa stood at the northwest corner and held the aluminum template. Then Liu Mou-fa gave a lifting signal to Bai Mou-mou, the driver of the No.17 tower crane, and lifted the aluminum template to the 15th floor to prepare for the installation of the aluminum template. During the lifting process of the tower crane, one of the U-shaped shackles with empty hooks was hung on the pedal at the northwest corner of the steel platform operating frame, and the steel platform was lifted, and the "corbel" stuck on the 13th floor under the east side of the rear steel platform moved from east to west and took off, and three workers and the steel platform fell together from the top of the shaft. During this period, it fell to the second floor after being buffered by the anti-falling hard quarantine facilities on the 12th, 9th, 6th and 3rd floors. After the fall, Liu Moumeng and Xiang Moumou climbed out of the elevator shaft door and found that Liu Moufa was still in the shaft. After the accident, Jingdong Construction Company immediately started the contingency plan, and removed Liu Moufa from the shaft, dialed 120 telephone calls, and sent three injured people to the North Hospital of Mount Hua Hospital for treatment and rescue. After diagnosis, Liu suffered skin abrasions; Xiang suffered minor injuries and was hospitalized. Liu died of ineffective rescue.
(2) Investigation
of the accident scene The accident occurred in Building 17, Block 0308-02, Unit BSP0-0103, a large residential community in Gucun, Baoshan. There is a tower crane with the site number of 17 on the south side of the building. The accident point is located at the elevator shaft on the east side of the 14th floor of the building. There is a yellow tower crane trolley hook above the elevator shaft, under which two lifting wire ropes are hung, one of which is hung with an aluminum formwork, and the other is hung with a U-shaped shackle. The elevator shaft is about 2100 mm wide and 1900 mm long. The aluminum formwork is attached to the wall. The steel platform of the elevator shaft has fallen to the second floor of the building. After investigation, the 12th, 9th, 6th and 3rd floors of the building are equipped with anti-falling platforms composed of steel plates and steel pipes, which have been collapsed by falling steel platforms layer by layer. The falling steel platform structure was left at the elevator shaft on the second floor, and a large amount of blood was left on the left side of the steel platform near the wall.

In the process of lifting, the U-shaped shackle was hung on the operating frame of the elevator shaft platform, causing the platform to fall after lifting.
(2) Indirect cause analysis
1.2.3.4.5
. Failure to pass the inspection means. Timely find out and correct the illegal command and operation behaviors of the carpenters.
6.
The main problems
existing in the responsible units (1) Zhaopan Real Estate Company failed to strictly supervise the construction units and supervision units to implement the on-site management responsibilities in accordance with the safety management norms of construction projects, and the supervision and inspection efforts were insufficient.
