Using the working envelope chart shown, determine the maximum permissible load on the working platform raised to a height of 19 m at a horizontal outreach of 11 m:Open full-size illustration
a
215 kg

215 kg

b
115 kg

115 kg

c
80 kg

80 kg

Correct answer

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 19 m and a horizontal outreach (wysięg) of 11 m is within the working envelope for a load (obciążenie) of 80 kg. It is beyond the 115 kg boundary, which allows approximately 10.7 m of outreach. Operation is therefore permitted, but with a maximum load of 80 kg.
