Question #766
Using the diagram, determine at which working radius the crane's rated capacity limiter will activate with a suspended load of 3320 kg:

8.5 m
8,5 m
Correct answer
b
9.5 m
9,5 m
c
10 m
10 m
d
7 m
7 m
Why?
The outer vertical section of the line labelled 3320 kg lies halfway between 8 and 9 m, giving a working radius (wysięg) of 8.5 m. Read the radius from the horizontal scale at the top, not the height scale on the right. Both 9.5 m and 10 m are beyond this boundary.
