What are the common causes of crane accidents? How to deal with it?

The causes of crane accidents mainly include two aspects: human factors and equipment factors. Among them, human factors are mainly due to the psychological reasons of managers or users such as taking chances, saving trouble and being rebellious, which lead to irrational behaviors. Material factors are mainly due to the equipment not being designed, manufactured, installed, maintained and serviced as required, especially not being inspected as required. Operating with "illness" thus sowing the seeds of potential safety hazards.

The main causes of crane accidents that account for a relatively large proportion are:

A. Violation of safety operation procedures, such as overloading or failure to confirm the weight of the lifted items, oblique pulling and lifting, standing at the bottom of the lifted load, unreliable binding of the lifted load, unreliable hooks and hooks, and operators lacking qualifications, etc.

B. The safety protection devices of the equipment are not installed or have failed. For instance, if the lifting height limiter, lifting weight limiter, moment limiter, hook anti-disengagement device, operation limit limiter, etc. are not installed or fail, the equipment grounding or zero connection is unreliable, or the leakage protection is unreliable, etc.

C. Inspection and testing work was not carried out as required. If a regular inspection system (such as pre-shift inspection, weekly inspection and monthly inspection, etc.) is not established and implemented, and the equipment is not reported to the supervision and inspection institution for acceptance inspection and regular inspection as required, it will result in the equipment being "faulty".

D. There are no safety supervisors or warning signs when maintenance work is stopped. For instance, if the operation of adjacent equipment is not monitored and warning signs are not hung on the ground power supply switch, etc.

E. Personnel engaged in maintenance and other operations fail to wear protective labor protection equipment as required.

F. The installation or dismantling of tower cranes was not carried out in accordance with the prescribed procedures;

G. When the truck crane was in operation, it failed to ensure the safe distance between the equipment and the lifted items and the wires in the working environment.

2. In response to the various causes of crane accidents, the user units should closely cooperate with the manufacturing, installation and maintenance units, as well as the crane machinery supervision departments and inspection and supervision institutions, strengthen management, implement all inspection systems, eliminate potential safety hazards, and minimize the possibility of accidents to the greatest extent. The user units must at least do the following work

A. We must earnestly strengthen safety ideological work. From safety staff to operators, maintenance and inspection personnel, all should cultivate safety awareness and consciously avoid unsafe behaviors.

B. Strictly follow safety operation procedures and eliminate any violation of operating procedures.

C. Establish a complete inspection and testing system and strictly enforce it;

D. Train and assess the operators.

3. Handling of lifting injury accidents

The handling of lifting injury accidents can generally be divided into five stages: on-site handling of the accident, investigation of the accident details, analysis of the cause of the accident, and conclusion of the accident case. The unit where the accident occurs should pay attention

After a lifting injury accident occurs, the employer must do everything possible to organize the rescue of the injured and state property, take effective measures to prevent the spread and expansion of the accident, and carefully protect the accident scene. Any objects, traces, conditions, etc. that may be related to the accident must not be artificially damaged. If it is necessary to move certain objects at the scene to rescue the injured, Signs, photos and detailed records must be well done.

2) While handling the scene, the affiliated unit should immediately report the general situation of the accident to the local safety supervision department and relevant competent authorities by phone, telegram or other prompt means.

3) After a clear analysis of the cause and responsibility of the accident, serious handling should be carried out in accordance with relevant laws and regulations.

Accidents where relevant leaders should be held accountable include:

A. The rules and regulations as well as safety operation procedures are not complete, leaving employees with no guidelines to follow.

B. Safety and technical training was not provided to employees, and they were ordered to start working without obtaining qualification certificates.

C. Lifting equipment has not undergone regular maintenance, has not passed safety inspection, or is still allowed to be used despite having defects.

D. Knowing that the equipment is in an unsafe environment but failing to take protective measures.

(2) Accidents where the perpetrator or relevant personnel are held accountable include:

A. Illegal command, illegal operation, and dereliction of duty;

B. Discovering an emergency but failing to report it or take emergency measures;

C. Disobeying management, violating labor discipline, leaving post without permission or moving equipment without authorization.
