Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower construction hoisting, in particular to water conservancy and hydropower hoisting equipment. Background Art

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. In the construction of water conservancy and hydropower projects, pipes are one of the indispensable building materials.
