Water transportation projects include coastal, offshore or inland river projects such as ports, waterways, breakwaters, revetments, ship locks, and shipyards. The existing small steel member hoisting devices for traffic water transportation construction are cumbersome to operate, resulting in a large amount of time consumed during operation, which affects the construction progress. Moreover, I-shaped steel members are economic section high-efficiency profiles with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. They have the advantages of strong bending resistance, simple construction, cost savings, and light structural weight, and have been widely used. However, for the installation construction of traditional upper steel members on the wharf, large cranes and flatbed trucks are required to transfer the I-shaped steel to the installation site. During hoisting, it is often necessary to move it with a hanger. When moving it currently, generally, the lifting claws are stuck at the lower end of the steel section. The distance between the two claw teeth of the existing lifting claws is fixed and cannot adapt to hoisting I-shaped steel members with different thicknesses and lengths.
