6 m
c
8 m
8 m
Correct answer
d
10 m
10 m
Why?
At a height of 17 m, the working envelope (pole pracy) boundary for 230 kg is at a horizontal outreach (wysięg) of approximately 8 m. Read the curve for 230 kg, rather than the outer outline of the entire chart. An outreach of 10 m exceeds the permitted limit for this load.
