Welcome!
In order to overcome the possible overturning of inflatable life rafts in the process of sea formation, avoid the difficulty of personnel launching and righting the raft, and meet the needs of survival personnel at sea for safety and rapid response, some manufacturers have developed inflatable self-righting life rafts. Once such life rafts are overturned on the sea surface during the deployment process, because the top of the raft is circular, the contact surface with the water can be reduced, and the sum of the weight of the raft body and accessories can make its center of gravity at the bottom of the life raft. After the life raft is inflated and formed, it can be self-righted.
Rigid life rafts are also known as traditional life rafts. Its structure is to use galvanized iron sheet, aluminum alloy plate, stainless steel plate or hard plastic materials to make a number of joint air boxes around the life rafts as the main buoyancy part of the life rafts, and then cover or not cover with flame retardant materials; The top of the raft is equipped with a fixed rigid roof and an entrance and exit, and the bottom of the raft is a wooden lattice plate. It is usually fixed and stored on the ship's side inclined slide or on the bridge deck, and the fixed hook of the slide is opened when releasing, so that the raft can slide down and launch by the slide or use the raft hanger to launch.
