Using the diagram shown, identify the correct crane operating parameters:Open full-size illustration
a
operation with the outriggers at minimum extension

praca na minimalnym wysuwie podpór

b
maximum reach of the boom with powered extension: 16.15 m

maksymalny wysięg wysięgnika z mechanicznym wysuwem 16,15 m

Correct answer

c
maximum lifting capacity: 25.1 t

maksymalny udźwig 25,1 t

d
answers a and c are correct

odpowiedź a i c jest prawidłowa

Why?

The main chart ends at a reach (wysięg) of 16.15 m, corresponding to powered extension, called mechanical extension (wysuw mechaniczny) in this question. The longer reaches use manual extensions R/S/T. The outrigger (podpory) symbol marked max requires full extension, and the maximum lifting capacity (udźwig) is 21.5 t, not 25.1 t.
