360 kg
360 kg
b
280 kg
280 kg
c
200 kg
200 kg
Correct answer
d
80 kg
80 kg
Why?
The point at an outreach (wysięg) of 4 m and a height of 22 m lies in the light 200 kg zone, not the 80 kg zone. This reading of the diagram identifies the intended answer. The question is imprecisely worded: working envelope (pole pracy) height must not be confused with platform floor height, whose maximum is 20.5 m.
