Question #430
Using the working envelope chart shown, identify the maximum horizontal outreach of the working platform carrying a load of 215 kg and raised to a height of 22 m:

7 m
Correct answer
b
6 m
6 m
c
8 m
8 m
d
10 m
10 m
Why?
At a height of 22 m, a horizontal line meets the upper boundary of the working envelope (pole pracy) at approximately 7 m of horizontal outreach (wysięg). This is the maximum outreach for a 215 kg load at this height. An outreach of 8 m is beyond the upper boundary, even though it would be permitted at a lower height.
