Claims

[Scope of utility model registration request]

The wire unwound from the hoisting winch and the elevating winch is wound around the tip of the boom via the support or boom, and the end stop side of the cargo handling wire is attached to a part of the drum of the elevating winch.
In a cargo lifting device mounted on a ship that winds the wire in the opposite direction to the winding direction, a hoisting sheave at the tip of the boom is provided at both ends of the outrigger of the boom, and the hoisting sheave at both ends of the outrigger is used for light load handling. It is equipped with a single acting pulley with a hook that is wound around the hoisting cable through each sheave, and for heavy duty, the single acting pulley can be attached to the boom using an outrigger.
A double-acting pulley with a hook is provided between each sheave at both ends and a single-acting pulley attached to the boom, and the hoisting cable is wound around a double-acting pulley with a hook, and the double-acting pulley is formed to be easily attached to and detached from the hoisting cable. A cargo lifting device for a ship, characterized in that the light load handling means and the heavy load handling means are configured to be switchable in use.
