spirlast

Norwegian to English Tech/Engineering Construction / Civil Engineering Scaffolding

..stillas bygget fra bakkenivå og opp ikke mer enn 38 m eller til maksimal spirlast i bunnkonstruksjon/ etasjehøyde oppnås.

I have translated "spir" as "standard", but I don't think "standard load" is correct. "Tensile load" maybe?
A google search yielded: upplagsreaktion (a Swedish article). Not sure if this means "reaction force".

Just to mention that in the file I'm translating there is also belastningssklasse, which I've translated as load class.

Thanks in advance.
