Single Arm Davit for Rescue Boat and Liferaft

This is a device used on ships, mainly composed of a single arm structure, a slewing device, a lifting device, and other parts. The single arm structure is its core support part, usually having sufficient strength and stability to carry the weight of the boat or raft. The slewing device enables the boom to rotate within a certain angle range, in order to move the boat or raft from the storage position to the water surface or lift it back onto the ship from the water surface. The lifting device is responsible for lifting and lowering the boat or raft.
