electric ladder , Iran

Cable ladders are constructed from high-density polyethylene HDPE or fiberglass reinforced with polyester resin. The mechanical strength of these materials under distributed load is minimum 250 kg per meter. Standard tray widths range from 150 to 600 mm with side rail heights of 50 to 120 mm. Rung spacing pitch length is typically 225, 300, or 450 mm with a ±2 mm tolerance. The cable tray depth is minimum 30 mm to maintain safe electrical clearance. The system provides IP40 to IP54 protection ratings for indoor and semi-outdoor environments. Thermal capacity is designed for cables with 70°C operating temperature per IEC 61537.

The ladder structure consists of longitudinal side rails, transverse rungs, and UV-resistant plastic connectors. The permissible installation slope without special fittings is up to 20 degrees. Support span for full load capacity is calculated for a maximum of 3 meters. The structural safety factor under dynamic loads is minimum 2.5 times the nominal load. Flame resistance complies with UL94-V0 standard with minimal flammability. Options include divider partitions, protective covers, and integrated grounding systems. The estimated service life in standard industrial environments exceeds 25 years.You can order and buy electric ladder from Iran by contacting us through whatsaap and email.
