ISO 16369:2007

Overview

ISO 16369:2007 - "Elevating work platforms - Mast-climbing work platforms (MCWP)" specifies particular safety requirements for mast-climbing work platforms that are temporarily or permanently installed. The standard covers MCWPs elevated by a drive system and guided along supporting masts (vertical or inclined up to 30°). It identifies hazards across the equipment life cycle and defines measures to eliminate or reduce risks for manually or power-operated MCWPs driven by electric, pneumatic, hydraulic motors or internal combustion engines.

Key Topics

• Scope & applicability: one or more masts; fixed or variable-length masts; tied or untied masts; standing or hanging masts; movable or static bases; excludes MEWPs, suspended access equipment and lifting tables.
• Structural and stability calculations: design verification and load assumptions for masts, base frames and chassis.
• Work platform requirements: main platform, platform extensions, available platform area and load diagram (permitted persons/materials).
• Drive systems: rack-and-pinion, screw drive, ratchet and other elevation drives; rated speed and transfer/transport conditions.
• Overspeed and fall prevention: overspeed detectors, overspeed safety devices, automatic brakes and mechanical stops.
• Emergency systems: provisions for emergency lowering/raising and buffers at travel ends.
• Overload/moment detection: devices and interlocks to prevent unsafe loading and tipping.
• Electrical, hydraulic and ICE drives: safety requirements for control systems, power supplies and auxiliary circuits.
• Controls, travel limit switches and verification: control ergonomics, limit switches, design checks and practical testing for new MCWP models.
• Information & marking: required instruction handbook content, load diagrams and machine markings.
• Annexes: structural calculation guidance, multilevel platform requirements, and electrical/electronic aspects for overload detection.

Applications

ISO 16369 is used by:

• Manufacturers and designers to design safe MCWP systems and prepare conformity documentation.
• Safety engineers and test laboratories for verification, type testing and risk assessment.
• Contractors, façade installers and building maintenance teams specifying MCWP performance, load diagrams and emergency procedures.
• Facility managers, regulators and insurers assessing compliance, safe use and operational training. Practical uses include specifying mast ties, selecting appropriate drive and braking systems, defining transfer/transport conditions, and preparing instruction handbooks and markings.
