Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shipbuilding, in particular to a hatch cover safety hook hoisting tool. BACKGROUND

[0002] Hatch cover accessory hoisting is an important link in the process of shipbuilding, which involves the stability and safety of the ship. During the installation of the hatch cover, the end stop device (safety hook) needs to be positioned on site. The traditional construction method is to hang a steel wire rope on the adjacent high hatch cover and use a manual hoist for hoisting and positioning during the construction of the project.

[0003] There are some disadvantages in using the traditional construction method on site: first, when using the traditional construction method, there is no high-altitude work platform to climb to a high place to hang the hoist, which makes it impossible to guarantee the safety of workers; second, when hoisting using the traditional construction method, if the hoist needs to be kept in the air temporarily without landing, the rope on the hoist will be damaged due to long-term hoisting of heavy objects, increasing the risk of injury and death caused by the falling of heavy objects due to rope damage; third, the traditional construction method uses a manual hoist for construction, and workers need to manually pull the rope to lift the heavy object, which consumes a lot of physical strength of the workers. At the same time, because the position of the manual hoist is only roughly above the heavy object, it takes a lot of time and effort for the workers to adjust the hook of the hoist to accurately fall near the heavy object, which also increases the labor intensity of the workers. SUMMARY
