Performance and attachments for marine lifebuoys

The marine lifebuoy, like the life jacket, is the most important tool in our marine lifesaving. Polyethylene lifebuoys are used to release smoke distress signals to get help when a ship is in distress.
Marine lifebuoy performance
Marine lifebuoys should be resistant to high and low temperatures, without shrinkage, rupture, expansion and decomposition. After the marine lifebuoy is thrown from the specified height, it should not crack or break. The lifebuoy should be oil-resistant, without shrinkage, rupture, expansion and decomposition. The lifebuoy should be fire-resistant and should not burn or continue to melt after overheating. The marine lifebuoy should be able to support 14.5kg of iron to float in fresh water for 24 hours. In the case of free suspension, the marine lifebuoy should be able to bear the weight of 90kg for 30min without cracking and deformation. For lifebuoys equipped with a spontaneous smoke signal and a quick-throw device attached to a self-lit floating lamp, the device should be triggered when released.
Marine lifebuoy attachments
The boat lifebuoy can be equipped with attachments, including a floating lifeline, a self-lighting floating lamp, or a self-emitting smoke signal.
