適用範囲

This standard applies to the design, manufacturing, and installation of fixed metal inclined ladders used in industrial enterprise workplaces. It is mandatory for all manufacturers producing such equipment for the Chinese market. It does not apply to ladders installed on nuclear facilities, ships, lifting machinery, or power transmission towers. It replaces the previous GB 4053.2-2009.

技術要求

The standard specifies comprehensive safety requirements covering angle of pitch and flight height (maximum 6m per flight). It details strict load-bearing capacities for stiles and treads, including uniform and concentrated live loads. Structural requirements encompass clearance dimensions, inside clear width, and specific combinations of going and rise dimensions. Manufacturers must ensure anti-corrosion and lightning protection measures are implemented according to referenced standards like GB 50057.

試験方法

Compliance is primarily verified through structural load assessments. The standard mandates that treads and stiles must withstand specified uniform and concentrated live loads without exceeding allowable deflection limits (e.g., 1/100 or 10mm for spiral ladders). Engineers must calculate structural integrity based on these load parameters rather than conducting a singular standardized physical test.
