How many loads can you put in 1 Bay?
Load increasing & length of Bay is decreasing
--->
Light duty scaffold
125kg/m2
3m length of scaffold pipe
Medium duty scaffold
250kg/m2
2m length of scaffold pipe
How many loads can you put in 1 Bay?
Light Duty Scaffold Bay = Length × Width
125kg/m2 ----> 1 Bay = 3m × 1.25m
=3.75M2
Final Result
Calculate total load of Bay = 3.75m2× 125kg/m2
= 468 kg (SWL)

How many loads can you put in 1 Bay?
2 Person + 250 kg
OR 3 Person + 150 Kg
OR 4 Person + 50 kg
