[0002] Aerial work in power construction refers to the installation, maintenance or overhaul of power facilities in a high-altitude environment. Such work usually involves the use of ladders, hanging baskets, scaffolding or safety vests, and workers need to follow strict safety procedures to prevent falls and other accidents. Among them, the safety vest for aerial work in power construction is a specially designed protective clothing, usually in high-visibility colors (such as fluorescent yellow or orange) to enhance visibility in high-altitude work environments. It may also be equipped with reflective strips, pockets and reinforced protective materials for additional safety and convenience. This vest is designed to ensure the safety of workers in high-risk environments such as power construction.
[0003] The prior art has the following deficiencies: the traditional safety vest is designed mainly to improve visibility, and is structurally the same as the traditional vest, and cannot directly provide fall protection.
