A marine winch is a large piece of equipment used to hoist cargo onto a ship. The marine winch can also be used to pull large cages and fishing nets up from the depths of the ocean and onto the deck of the shop.
This type of winch is made up of a hydraulic motor and a large drum or spool. The most commonly used marine winches include a transmission or gearbox that allows the winch marine to power the rope, next and cable out and away from the vessel.
Marine winches are typically mounted on the rear end of the deck, or behind the Captain’s or control house.
While most vessels are loaded by heavy-duty dock cranes hoisting cargo up from the dock and transferring it onto the vessel’s holding area or deck by the marine running a rope up and over a tall tower or outrigger on the vessel’s deck. The marine winch is used on remote or smaller docks where a heavy-duty dock crane is not readily available. In such instances, the marine winch is used instead of the crane. The crew on the ships is responsible for loading the vessel for travel.
Once at sea, the marine winch is used for different tasks such as fishing and pulling heavy objects. When the crew is using large fishing nets, the ropes attached to the next can be connected to the spool and the winch can be used to pull heavy loads out of the water and onto the holding area on the ship. When crab or lobster fishing, the marine winch can be used to set the large net pots or cages and raise them from the depths of the sea.
A rope, typically attached to pots on one end and to floating buoys on the other end, is connected to the winch and pulled up to the ship’s crew waiting on the deck. This kind of marine winch does not attach the rope around the spool. Instead, the winch retracts the rope and piles it up on the rear end of the winch. The ship’s crew can then tie the rope around a barrel to keep order and prevent tangling as it leaves the winch.
A marine winch can also be used to lift and place bulky loads on the vessel’s deck, as well as to stack and organize fishing gear on the holding area or deck of the ship. Marine winches are also used to unload vessels when it arrives at a port.
Marine winches can be categorized based on the mode of control (either manual or automatic tension), drive type (electric, hydraulic, or steam), number of drums on each drive, type of drums (undivided or split) and by their brake application and brake type (spring applied, mechanical screw, disc or band). There are electric winches, hydraulic winches and diesel winches etc.
Finally, marine winches are critical in securing the shipboard and to compensate for shifts in tide and draft. General requirements for marine winches are regulated within ISO Standards 7825 and 3730. Marine winches also play a critical role in the smooth loading and offloading of freight at ports in various parts of the world.
