How do you calculate H frame scaffolding?
Following is the formulae that can be used for calculating the quantity of ‘H’ frames and other components:
- ‘H’ frames: L/B + 1) x (H/h)
- Cross Brancings: (L/B) x (H/h) x 2.
- Base Jacks: (L/B + 1) x 2.

How is SWL calculated?
SWL or WLL are calculated by dividing MBL by a safety factor (SF). An example of this would be a chain that has a MBL of 2000 lbf (8.89 kN) would have a SWL or WLL of 400 lbf (1.78 kN) if a safety factor of 5 (5:1, 5 to 1, or 1/5) is used.
