Analysis of the possible causes of heavy objects falling during the use of jib cranes

In the whole process of the operation of the jib crane, if the lifting object falls, it will pose a great threat to the production safety. Therefore, people should know the reasons why the heavy objects of the lifting equipment fall, and strengthen the prevention to prevent the occurrence of safety production accidents. Below, we have asked the technical staff of the manufacturer of the jib crane to introduce to you the reasons that may cause the fall during the lifting process:

1. Design defects of jib crane products

If the original cantilever crane is not designed according to the standard production requirements, it will have certain design defects, the product does not have certain protection measures or the overpressure protection is invalid, the compressive strength of the balance shaft is insufficient, there is no equipment to avoid decoupling, slings and rigging Risks such as using unscientific.

2. Manufacturing defects and installation defects

If there are some problems during the use of the product, in addition to the possibility of defects in the original product design, it can also be caused by poor material selection and poor production and processing quality. These mechanical equipment with potential safety hazards will also have major safety hazards. .

3. Improper maintenance

If the jib crane is not maintained in time during the application stage, the above problems may also occur, such as failure to disassemble and replace damaged parts immediately, lack of necessary safety precautions, and improper maintenance operations lead to damage to parts or structures, etc. In other words, shortcomings at all stages of design, manufacturing, installation, application and testing can create a serious danger of a hook falling.

4. Environmental factors

Harsh natural environments that exceed safety limits or standard requirements, such as high temperature, ultra-low temperature, high noise, strong wind, poor light and other natural environments, will distract and concentrate attention, affect the reliability of operators' ability to reflect work and technology, and increase operation Opportunities for mistakes and traffic violations to operate safely, resulting in safety accidents. On the other hand, the harsh environment for safe operation will also lead to the reduction of the function of the lifting equipment system software itself, thereby accelerating the failure of components or structures, becoming the fourth factor of insecurity.
