The single-arm rescue boat/raft lowering and lowering equipment is an important life-saving device in the marine industry. It adopts the single-arm transition design with electric (manual) lifting, gravity lowering and hydraulic rotating functions, which can realize the lifting and lowering of rescue boats or rafts, the recovery and the lifting of miscellaneous objects in the port operation. The equipment is flexible in operation, supports engine-side maneuvering and in-boat remote control, and can work safely under thebad sea conditions when the ship is tilted. Meanwhile, it is equipped with a brake device to ensure safe and reliable operation, which is in line with the international life-saving equipment rules and the requirements of the relevant conventions, and it is applicable to large and medium-sized ships, and it is the key equipment for emergency rescue of the ship.
