Description

Technical Field

[0001] The utility model relates to the technical field of cement pier hoisting tooling, in particular to a marine steel structure cement pier hoisting device. Background Art

[0002] In the manufacture of offshore steel structures, cement pads are often needed as structural supports and counterweights. They are frequently used and require frequent lifting and storage. These cement pads require flat upper and lower surfaces and no lifting points. Traditional lifting methods often involve threading wire ropes / slings through embedded parts for installation. This is inconvenient, difficult, time-consuming, and labor-intensive, and the wire ropes are easily abraded at the perforations. Alternatively, the holes in the embedded parts do not match the wire ropes / slings, making threading impossible. Alternatively, traditional slings are used to tie the cement pads. The slings are heavy, labor-intensive, and require the cement pads to be elevated and passed through from below. Therefore, a new type of tooling is needed to facilitate lifting, avoid wear and tear on the wire ropes / slings, which can create safety hazards, and avoid the problem of mismatched perforation sizes between the wire ropes / slings and the inconvenience of threading the wire ropes / slings.
