Why?
The working envelope diagram (wykres pola pracy) shows that the 200 kg envelope, marked with a two-person symbol, includes a height of 24 m. Two people may therefore be raised, provided the outreach stays within that envelope and the combined mass of people, tools and materials does not exceed 200 kg. The one-person symbol applies to the 80 kg envelope and does not indicate the maximum number of people at this height.
