How to Find Load Capacity of Scaffolding?
Definition
Scaffold load capacity is the maximum weight that a scaffold platform can safely support including workers, tools, and materials.
Details
Scaffold capacity is determined based on design and classification. According to scaffold safety rules referenced in Occupational Safety and Health Administration, scaffolds must support at least four times the intended load.
Typical scaffold load classifications:
Type Load Capacity
Light duty 120 kg/m²
Medium duty 240 kg/m²
Heavy duty 360 kg/m²
When calculating scaffold load consider:
Weight of workers
Tools and equipment
Stored materials
Platform area
Design of scaffold system
Example
If a scaffold platform is designed for 240 kg/m² and its area is 4 m², the total safe load is:
240 × 4 = 960 kg maximum load
Workers, tools, and materials together must not exceed this limit.
