This is an auxiliary machine that is not directly related to the propulsion of a ship and is not installed in the engine room.
It is also known as the deck auxiliary machine.

It includes loading unloading machinery (winch, crane, etc.), mooring winches, anchor capstans,and other equipment designed to lift or lower life saving boats or traps, Steam power is used as the power source for the deck machinery . Even though dierct driving methods such as direct internal combustion engine is used in small ships, performance depends on the type of propulsion engine, requirement performance price and other considerations related to auxiliary devices for the engine power standard but more AC machinery is being adopted as electric power is being required in ships.

The winch is the device driving elevator or escalator

The winch for elevators as especially designed nit to rotate in the reverse direction. Also the winch should incorporate technology that will not lower stability in driving and prevent the generation of noise during the driving.

Winch : is the machine to lift or lower the load by winding or unwinding a wire rope on the cylindrical drum and using the tackle block
