In order to ensure the safe use of single crane hook blocks, we must choose high quality products.
We all know what a hook is. A hook is used mainly for cranes. So what is the reason that the hook falls suddenly when the cargo is lifted?
There are several reasons for cargo falling from lifting hook:
1. Unsafe condition of crane
The first is the risk brought by the non-standard design, such as overload protection failure, insufficient strength of balance wheel shaft, no anti-decoupling device, unreasonable selection of spreader and rigging.
Secondly, manufacturing defects and installation defects, such as improper material selection and poor quality of processing, make equipment with hidden risks put into use.
A large number of problems exist in the process of use, such as not replacing the scrapped parts in time, lack of necessary safety protection, poor maintenance and operation with diseases, resulting in out-of-control movement, parts or structural damage, and irregular safety performance inspection.
In conclusion, any defects in design, manufacture, installation, use and inspection may lead to serious consequences of falling objects.
The essential safety of crane (design, manufacture and installation) is the basic condition to ensure the safety of lifting operation.
2. Unsafe human behavior
People's behavior is affected by a variety of factors such as physiological, psychological and comprehensive quality, which is manifested as unskilled operation skills and lack of necessary safety education and training.
Non-driver operation without license;
Violation of regulations and discipline, bad operating habits;
Judgment of operation error, unclear command signal, improper coordination between lifting driver and lifting heavy industry and human biological rhythms in the "three high zones", etc.
In summary, poor safety awareness and poor operational skills are the main man-made causes of accidents.
3. Environmental factors
Exceed safe limits or health standard of bad environment, such as the high dust, high temperature, high humidity, low temperature, high noise, windy day, engaged in lifting operations and poor lighting environment, will be a distraction, a direct impact on homework personnel's ability to respond to, the stability of the technology, the opportunity to make the wrong operation, illegal operation, lead to accidents.
In addition, the poor working environment will reduce the crane system function and even accelerate the failure of the zero part (structure), which becomes one of the unsafe factors.
4. Defects in safety management
Management includes the level of safety awareness of the leader;
The implementation of crane management, inspection and regular safety performance inspection;
Safety education and training for relevant personnel;
Special training for crane operators, formulation of crane safety operation rules, establishment of reward and punishment system for violation of regulations and accident emergency plan, lack of effective monitoring and management of periodic inspection of lifting equipment and lifting accessories, etc.
Any negligence and inadequacy in safety management is one of the important reasons for the accident.
The human reason has the thing factor
To strive for the equipment selection, safety protection measures, building, the lifting process, the working environment, regular check, etc., according to the relevant lifting machinery safety regulations and standards of the state to carry on the design, equipment purchase, installation, construction, from the two aspects of people, objects, using unit should make a crane operation, maintenance and management of safety rules and regulations and operation procedures.
At the same time, should realize soberly, in accordance with the relevant provisions of the state of special equipment safety management, to use assistive devices) (including hoisting crane safety performance for regular inspection, is to ensure that in the safe operation of the hoisting equipment, reduce that eliminate the metallurgical crane hook hanging objects fall injury accident happened one of the necessary guarantee conditions.
