Description

Technical Field

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

[0002] In construction, cranes are needed to transport heavy steel structures to high places for installation. During the construction process, the usual practice is to use ropes to bind the outer walls of the steel pipes, and then hang the ropes on the hooks of the crane for lifting and moving. However, the rope binding method is very troublesome to operate, resulting in low efficiency in lifting steel pipes. At the same time, during the lifting process, the rope binding method makes it difficult to control the center of gravity of the steel pipe, resulting in the steel pipe tilting during the lifting process, posing a safety hazard of falling. Therefore, we proposed a steel structure profile lifting device to solve the above-mentioned problems. Utility Model Content
