Open full-size illustrationa
the maximum lifting height with two people is 23 m
maksymalna wysokość podnoszenia z dwiema osobami 23 m
b
the permitted number of people on the platform is 2
dopuszczalna ilość osób na platformie - 2
Correct answer
c
the maximum outreach with one person on the platform is 12 m
maksymalny wysięg podestu z jedna osobą na platformie 12 m
d
all answers are correct
wszystkie odpowiedzi są poprawne
Why?
The two-person symbol beside 200 kg confirms that two people are permitted on the platform within the corresponding working envelope (pole pracy). The combined mass of people and equipment must stay within 200 kg. The floor of the highest platform shown is above 23 m, so 23 m is not its maximum lifting height (wysokość podnoszenia). This also rules out “all answers are correct”.
