The life raft is a special raft body used for escape and survival of sea survival personnel. The inflatable liferaft is the most widely used liferaft, among which the most common is the throw-on liferaft.
When using a throw-and-drop life raft, the raft and the storage tank can be thrown directly into the water together. The life raft can be automatically inflated and formed for people in distress to ride. If the ship sinks too fast to throw it into the water, when the ship sinks to a certain depth, the hydrostatic pressure release device on the raft will automatically unhook, release the life raft, and the life raft will surface and automatically recharge. Bulging.
The cast steps are as follows:
1. Pull off the opening of the upper chain hook of the hydrostatic pressure release device slightly, push out the small loop to make the chain hook fall, or rotate the manual unhooking device upward, and the raft will slide from the raft frame to the sea. Or manually lift the raft and throw it into the water.
2. If the raft storage deck is less than 11m above the water surface, or when the raft is thrown into the water and has not expanded, continue to pull out the first cable and open the valve of the inflatable cylinder to make the raft inflated and formed to float on the sea.
3. After the raft enters the water, if it is overturned, it should be righted. The righter should wear a life jacket, climb to the bottom of the raft, stand on the side of the steel cylinder, pull the bottom righting belt with both hands, squat and lean back, paying attention to the wind and righting.
