W oparciu o przedstawiony diagram wskaż poprawne parametry pracy żurawia:

Using the diagram, identify the correct operating parameters of the crane:Open full-size illustration
a
maximum lifting height of 13 m

maksymalna wysokość podnoszenia 13 m

b
maximum working radius of 15 m

maksymalny wysięg 15 m

c
maximum lifting capacity at a working radius of 14 m is 2.4 t

maksymalny udźwig na wysięgu 14 m wynosi 2,4 t

d
maximum lifting capacity at a working radius of 6.8 m is 4.3 t

maksymalny udźwig na wysięgu 6,8 m wynosi 4,3 t

Correct answer

Why?

The curve labelled 4300 kg reaches a working radius (wysięg) of approximately 6.8 m, corresponding to a lifting capacity (udźwig) of 4.3 t. The lifting height (wysokość podnoszenia) reaches approximately 15 m, but this does not mean the working radius is also 15 m. A distance of 14 m is outside the operating range shown.
