Ensure that the tower crane safety protection device is complete.
Make them understand the structure and working principle of the lifting equipment, be familiar with the safety operation rules and strictly carry out the work with certificates.
It is suggested that the relevant departments formulate a scrapping scale for tower cranes and resolutely scrap them when the service life is up.
According to netizens, on January 2, 2023, a tower crane collapsed at a construction site in Ningbo, Zhejiang.
6.
Common lifting height limiter, amplitude limiter, lifting weight limiter, lifting weight limiter, etc.
Strengthen wind protection measures.
Operate in strict accordance with the requirements, and overload operation against rules is strictly prohibited.
In addition, the safety of adjacent equipment shall also be considered, for example, the vibration generated during the operation of adjacent machinery will affect the tower crane foundation; The bearing capacity of foundation will be changed during excavator operation; Collision may occur when tower cranes are operating in close proximity.
As the end of the New Year approaches, all major construction sites begin to prepare for the “final battle”, and the construction rhythm is also obviously tense.
Please refer to the official investigation and announcement.
At present, many provinces have forcibly prohibited the use of tower cranes produced by some manufacturers, but there is no same scrapping scale for the service life of tower cranes.
It can be seen from the picture that the tower crane foundation is set in the basement, and the tower body bends 90 ° at the reserved hole on the top plate, and finally hits the adjacent main building structure.
The safety department shall increase the frequency of on-site safety disclosure and patrol inspection, resolutely prevent on-site violations, and strive to ensure safe and orderly construction during the rush period before the festival.
Strictly implement the tower crane operating procedures.
The wind interferes with the normal operation of the tower crane.
I wish you all a peaceful and happy New Year home in your busy work before the festival! Preventive measures for tower crane safety accidents 1.
The specific cause of the accident is still under investigation.
2.
Technical preparation, risk analysis and technical disclosure of hoisting equipment are important links to ensure the safe and smooth completion of large-scale hoisting…
As the height of the tower crane increases, the impact of the wind will be greater, especially in windy seasons and coastal areas.
Insist on regular inspection and maintenance of tower cranes by professional staff, which can effectively prevent safety accidents.
Accurately evaluate the service life of tower crane.
Strengthen the safety inspection, maintenance and regular daily maintenance of tower cranes.
5.
3.
The tower crane must be operated by special personnel.
4.
Face up to the tower crane foundation design and accurately handle the safety of adjacent equipment.
Such as cracks and bad welds, if the maintenance is not timely, it will endanger the safety of the tower crane.
The uneven foundation soil will cause the tower crane to tilt.
7.
Because of the rush period and progress, workers are facing more and more work, which inevitably leads to psychological and physical fatigue.
The wire rope shall be inspected and maintained frequently, and shall be replaced immediately when reaching the scrapping standard.
In order to prevent the longitudinal and transverse inclination from exceeding the specified value, the laying of subgrade track shall be strictly required.
Technical and safety training shall be carried out for drivers, installation and disassembly personnel and maintenance personnel in a planned way.
