Material and Craftsmanship Details
The speed reducer body uses education-grade YL104 die-cast aluminum, precision-machined and surface-treated, with 60% improved impact resistance over standard aluminum alloys. The steel cable uses 42mm diameter high-strength alloy steel, 1200°C heat-treated, with 2500kg tensile strength, covered with blue anti-wear protective sleeve preventing damage from improper student handling. The safety belt features orange high-visibility design, 5cm wide special nylon material, quickly identifiable even in smoke-filled environments. The triangular mounting plate uses thickened SPCC steel, withstanding lateral forces in extreme situations like earthquakes.
Color/Style Display
This kit follows educational industry safety equipment standard coloring, with a black body speed reducer featuring bright orange markings for quick identification in low-light environments; orange high-visibility safety belt meeting GB8624-2012 national safety standards; original color steel cable with blue anti-wear protective sleeve combining aesthetics with functionality; and silver aluminum alloy storage box offering lightweight, durable, and corrosion-resistant properties for long-term campus use. This color combination is both visually appealing and provides intuitive operational guidance during emergencies.
Application Scenarios
Teaching Building Fire Evacuation: When fires block stairways with smoke in multi-story educational buildings, deploying two School Safety Escape Descender Kits per floor window enables safe evacuation of a standard class of 40 students within 8 minutes, with 99% evacuation success rate.
Library Emergency Rescue: During earthquakes blocking main library exits, pre-installed descenders help staff guide readers to safety through windows, each kit evacuating 25 people per hour, significantly reducing injury risks.
Dormitory Night Escapes: When night fires fill corridors with smoke, students can use window-mounted descenders for quick escape, with orange high-visibility design providing clear guidance in darkness, reducing average escape time to 40 seconds and improving survival rate by 80%.
