CAD Design for a 400kg Movable Platform Ladder
Steel Service Ladder Design for Overhead Machine Access
A movable service platform ladder designed for safe access to machine components, equipment mounted at height, or high warehouse shelving. Steep stairs with safety handrails and a grated top platform give operators a stable working position without hydraulic or electric lifts. The main frame is bolted steel, painted, while the stairs and top platform grating are hot-dip galvanized for durability.
