14,5 m
b
20.0 m
20,0 m
Correct answer
c
16 m
16 m
d
17.5 m
17,5 m
Why?
The upper hatched area has a lifting capacity (udźwig) of 6800 kg, so a 6470 kg load is permitted there. With the boom raised, the lifting height (wysokość podnoszenia) in this area reaches approximately 20.0 m. The value 17.5 m refers to the right-hand end of this area, not its highest point.
