20,7 m
c
10 m
10 m
d
17.9 m
17,9 m
Correct answer
Why?
The 1290 kg curve runs up from the 10.30 m outreach (wysięg) point to the outer edge of the working range. To the left of it the permitted lifting capacity (udźwig) is even higher, so a 1290 kg load can be raised to the highest point of the working range, a lifting height (wysokość podnoszenia) of approximately 17.9 m. The 20.70 m value is the outreach with manual extensions at a lifting capacity of only 445 kg, not the height for 1290 kg.
