What are the factors that cause objects lifted by lifting hooks to fall?

Factor 1: The unsafe condition of the crane itself
The first is the risk caused by non-standard design, such as overload protection failure, insufficient strength of the balance axle, no anti-decoupling device, unreasonable selection of spreader rigging, etc.;The second is manufacturing defects and installation defects, such as improper material selection and poor processing quality, which puts equipment with hidden dangers into use. A large number of problems exist in the use process, such as failure to replace scrapped parts in time, lack of necessary safety protection, poor maintenance and diseased operation, resulting in out-of-control movement, damage to parts or structures, and irregular safety performance inspections. In short, defects in any aspect of design, manufacturing, installation, use and inspection may lead to serious consequences of the hook hanging objects falling. The essential safety of cranes (design, manufacturing, and installation) is the basic condition to ensure the safety of lifting operations. Factor 2: Unsafe behaviors caused by humans Human behavior is affected by many factors such as physiology, psychology and comprehensive quality, which are manifested in unskilled operating skills, lack of necessary safety education and training; non-driver operation, working without a license; reckless behavior in violation of rules and disciplines, bad operating habits; misjudgment of operations, unclear command signals, uncoordinated cooperation between lifting drivers and lifting workers, and human body biorhythms in the "three high zones", etc. In short, poor safety awareness and low operating skills are the main human causes of accidents. Factor three: the influence of environmental factors Unfavorable environments that exceed safety limits or hygienic standards, such as lifting operations in environments with high dust, high temperature, high humidity, low temperature, high noise, strong winds, poor lighting, etc., will distract the attention, directly affect the reaction ability of the workers and the stability of technical performance, increase the chances of misoperation and illegal operations, and lead to accidents. In addition, a poor working environment will also cause the crane system itself to degrade in function and even accelerate the failure of parts (components), becoming one of the unsafe factors. Factor 4: Loopholes in security management Management includes the safety awareness level of leaders; the management, inspection and implementation of regular safety performance inspections of cranes; safety education and training for relevant personnel; special training for lifting operators, the establishment of crane safe operation rules and violation reward and punishment systems and accident emergency plans, and the lack of effective monitoring and management of regular inspections of lifting equipment and lifting aids, etc. Any negligence or failure in safety management is one of the important reasons for lifting casualties. To sum up, there are human reasons and physical factors that we should strive to design.In terms of alternative types, safety protection measures, factory construction, lifting processes, operating environment, regular inspections, etc., the design, equipment purchase, and installation construction should be carried out in accordance with the relevant national lifting machinery safety regulations and standards. Starting from both the human and material aspects, the user should formulate safety rules and operating procedures for crane operation, maintenance, and management. At the same time, we should be clearly aware that in accordance with the relevant national regulations on the safety management of special equipment, regular testing and inspection of the safety performance of cranes in use (including lifting aids) is one of the necessary guarantees to ensure the safe operation of the lifting equipment in use, and to reduce or even eliminate the occurrence of accidents involving falling objects from metallurgical crane hooks.Factor 1: The unsafe condition of the crane itself
