Description

Technical Field

[0001] This utility model relates to the field of steel structure installation technology, and in particular to a movable protective basket for steel structure installation. Background Technology

[0002] In building construction, steel structure installation is a crucial step in steel structure engineering, and its quality directly affects the safety, stability, and durability of the entire project. Therefore, strict adherence to relevant technical specifications and standards is essential during steel structure installation to ensure installation quality. Several risks exist during steel structure installation, which not only affect project progress and quality but also threaten worker safety. Specific defects include: steel structure installation often involves working at heights; inadequate safety measures could lead to workers falling from heights; unstable temporary work platforms, improper use or absence of safety belts can also cause falls from heights; the lack of effective anchor points for safety belts and insufficient lifelines covering the entire work area; the need for repeated disassembly and assembly of scaffolding or temporary platforms, preventing flexible movement along steel beam tracks, resulting in low construction efficiency; and the need for continuous power support for high-altitude work, with cables often dragging around the platform, making them susceptible to snagging on steel components and potentially causing electrical leaks.
