operation is prohibited because the permissible operating parameters are exceeded
praca niedozwolona ze względu na przekroczenia dopuszczalnych parametrów pracy
b
215 kg
215 kg
Correct answer
c
115 kg
115 kg
d
80 kg
80 kg
Why?
The position at a height of 18 m and an outreach (wysięg) of 8 m lies within the work envelope (pole pracy) for 215 kg. The outreach limit for this load is about 8.2 m, so it has not been exceeded. Loads of 115 kg and 80 kg are also permitted, but the question asks for the maximum permissible load.
