Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a device for transporting and installing steel structure components in a narrow space and a construction method thereof. Background Art

[0002] In recent years, steel structure projects have become increasingly common in residential areas, commercial complexes, large venues, and other fields. At the same time, they have also demonstrated many advantages in the renovation of old buildings, such as small impact on the structure itself, high safety, fast construction efficiency, and obvious environmental protection and energy-saving effects.

[0003] In new construction or renovation projects, the transportation and installation of steel structures within confined spaces is a common occurrence. This process involves both vertical and horizontal transport and installation of the steel structure. While lighter components can be easily transported using hand winches or dragging, larger and heavier components often present operational challenges, including irregular operations and high safety risks.
