The safety of large-scale machinery has always been a topic that cannot be avoided in the industry, because the quality of the machinery itself is very large, no matter what failure occurs, the risk factor will be superimposed to the highest, and because of the specific use environment of marine winches, the risk factor is relative to that on land. The winch used will be a little higher.
For the specific reasons, it is necessary to mention the state of the marine winch under normal operation. Regardless of the pneumatic or electric driven marine winch, it operates at a uniform speed during operation, but many operators will lose patience because of the slowness. Therefore, regardless of the load limit, it will start to run, because the quality of the marine winch itself is very large, and it will enter a dangerous range at this time.
If it is under the load of the marine winch, forcibly braking and stopping after the operation is completed, it will cause the risk of equipment damage, and the brakes inside the equipment will also reduce the life of the brake disc due to the braking and stopping after this high speed. Of course, this is still within the controllable range. Inside.
If it exceeds the load of the marine winch, if the operation is not stopped after the operation is completed, the equipment will idling and lead to the secondary release of the towed items such as ropes. Fever leads to failure to stop, creating a greater risk.
Through the case analysis of incidents of marine winches in the past, the cause of marine winch accidents is mainly manifested in the case of not fully grasping the use of equipment parameters, and the ability to predict and predict accidents is extremely lacking. Most operators are using The attitude during the equipment process is very lax.
These will lead to frequent accidents. EME has a standard operation manual in the equipment manual, and repeatedly warns that it must read the operation manual before starting the operation. Most operators still believe in empiricism, which leads to too many operation accidents.
Such frequent violations, the lack of clear draft rules for critical areas and specialized equipment, and the lack of clear labor management and personnel safety awareness have resulted in a high risk of marine winch accidents.
Enterprises should strengthen their awareness of the importance and urgency of machinery operation management, establish and improve practical management standards, and implement them conscientiously.
