Champ d’application
This standard applies to fixed steel vertical ladders used in workplaces within industrial enterprises. It covers the basic safety requirements for the design, manufacture, and installation of these structures. This standard is mandatory except for the terms and definitions chapter. It does not apply to ladders that are regulated by other specific standards.
Exigences techniques
The standard specifies material requirements, mandating that the mechanical properties of steel shall not be lower than Q235-B with a qualified carbon content guarantee. It also outlines the design load limits, including specific vertical concentrated live loads for stiles, rungs, and supports. Manufacturers must ensure all structural components can withstand the specified loads without exceeding allowable deflection limits. In terms of structural design, the standard dictates the inclination angle (75° to 90°), inside clear width, and ladder section height limits. It mandates the use of safety cages when the climbing height exceeds specific thresholds to prevent falls. Additionally, it details the dimensional requirements for rungs and stiles, which vary depending on whether the ladder is used in normal or abnormal environments, such as damp or corrosive conditions. The standard also addresses manufacturing and installation practices, requiring welded connections in compliance with GB50205. It mandates anti-rust and anti-corrosion measures, such as painting or hot-dip galvanizing, and requires lightning protection grounding for outdoor installations in accordance with GB50057.
Méthodes d’essai
This standard primarily focuses on design, manufacturing, and installation specifications rather than laboratory testing methods. However, compliance assessment involves structural verification of load capacity to ensure stiles, rungs, and supports can endure the specified vertical and pull-out loads. Visual and dimensional inspections of anti-corrosion coatings and structural integrity are also required to verify adherence to the manufacturing standards.
