c

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 15 m and an outreach (wysięg) of 10 m lies outside the permissible working envelope (pole pracy). The chart has only one envelope, marked 200 kg, and does not provide a larger outreach for a lighter load. Operation in this position is therefore prohibited at any load.
