Description

Technical Field

[0001] The present application relates to the technical field of lifting tools, and particularly relates to a special lifting tool for underwater gabions. Background Art

[0002] As a new ecological grid structure of new technology, new technology, and new material, the gabion has been successfully applied to water conservancy projects, highway, railway projects, and embankment protection projects, and has better realized the organic combination of engineering structures and the ecological environment. A special lifting tool is required during its installation.

[0003] After the existing lifting tool is hooked at the connection with the gabion, it is impossible to intercept the opening of the hook body. As a result, after the buoyancy of the hook body rises when it enters the deep underwater, the hook body is easily disconnected from the connection with the gabion automatically, which will cause the gabion to be unable to be installed at the designated position and affect the working efficiency of the staff.
