could be used for ordinary scaffolding in all ceilings with concrete slabs and beams. The props have a 1.5m bearing capacity and they are designed and supplied for 3.5m geight the props for different heights could be supplied according to the customer's order.

k=1m . l=300cm
s=kl/r=(1×300)/(1∙76)=170∙45

ce=√((2π^2 e)/fy=131∙4)

kl/r=170∙45>ce=131∙4

Fa=(π^2 e)/〖f∙s(kl/r)〗^2 F∙s=1∙92

fa=π^2 E→1∙92×(170∙〖45〗^2 )=371∙5kg

P=1∙4ton
p=fa×A→371∙5×3∙73≈1385
