d
all answers are correct
wszystkie odpowiedzi sa prawidłowe
Why?
The maximum working height (wysokość robocza) of 10.5 m includes the platform floor height plus an assumed worker reach of about 2 m above it. Lifting height (wysokość podnoszenia) is measured to the platform floor, which is approximately 8.5 m here, rather than 9 m. Working outreach (wysięg roboczy) is a horizontal distance, so the vertical dimension of 10.5 m does not describe it.
