Product Highlights:
- Made of thickened aviation aluminum, lightweight yet high rigidity, anti-rust, corrosion-resistant, long service life for long-term heavy-duty use.
- Heavy-duty design, with a 300 lb weight capacity, making it durable enough for industrial, commercial, and residential use.
- The triangular support at the bottom of the ladder greatly improves the overall structural stability and effectively disperses the bearing pressure during climbing.
- Maximum reach of 41.27 feet (12.58 meters), ideal for high-reach tasks, whether you're working on installations or performing maintenance.
- EN131 compliant. Available for use across South America, including Peru, Chile, and Argentina, meeting the specific needs of the region's workforce.
- 3.0mm thick solid aluminum beam + 75mm widened ladder side frame, high load-bearing capacity, no bending or deformation under heavy weight, improves overall safety.
- Optimized anti-reverse tooth locking mechanism, smooth lifting without jamming, firmly locks ladder height at any position, avoids accidental slide-down.
- Extra large thick rubber foot pad with anti slip serrated bottom. Provide strong friction on various surfaces to prevent sliding and floor scratches.
Whether you need a ladder for high-reaching tasks, telecommunications work, or industrial use, the DY-XXX Aluminum alloy three-in-one lift provides the safety, durability, and convenience required for demanding environments.
