Using the working envelope chart shown, determine the maximum permissible load on the work platform at a height of 26 m and a horizontal outreach of 7 m:Open full-size illustration
a
100 kg

100 kg

Correct answer

b
200 kg

200 kg

c
230 kg

230 kg

d
operation is prohibited because the permissible operating parameters are exceeded

praca niedozwolona ze względu na przekroczenia dopuszczalnych parametrów pracy

Why?

The point at a height of 26 m and a horizontal outreach (wysięg) of 7 m lies near the outer boundary of the working envelope (pole pracy) for 100 kg. It is outside the envelopes permitted for 200 kg and 230 kg. Operation is therefore allowed, but only with a load of up to 100 kg.
