Using the working envelope diagram shown, determine the maximum permissible load on the work platform raised to a height of 15 m at an outreach of 11 m:

360 kg
b
280 kg
280 kg
c
200 kg
200 kg
d
80 kg
80 kg
Correct answer
Why?
The point at a height of 15 m and an outreach (wysięg) of 11 m lies in the darker zone marked 80 kg. The light 200 kg zone does not extend to that point. The platform's maximum load capacity (udźwig) does not apply everywhere in its working envelope.
