280 kg

c
200 kg

200 kg

d
Operation is prohibited because the permissible operating parameters are exceeded

praca niedozwolona ze względu na przekroczenia dopuszczalnych parametrów pracy

Correct answer

Why?

The point at a height of 22 m and an outreach (wysięg) of 9 m lies outside the entire permitted work envelope (pole pracy). A load of 200 kg is permitted only within its designated zone, and this point is outside even the 80 kg zone.
