80 kg

d

praca niedozwolona ze względu na przekroczenia dopuszczalnych parametrów pracy

Correct answer

Why?

At an outreach (wysięg) of 11 m, a height of 21 m exceeds the upper boundary of the work envelope (pole pracy), even for 80 kg. Operation in this position is prohibited. The load capacity (udźwig) of 80 kg at 11 m outreach applies only within the permitted height range, not at every height.
