Question #765

Using the diagram, determine beyond which working radius the rated capacity limiter will activate on the crane designated 600 T with a suspended load of 700 kg:

W oparciu o przedstawiony diagram określ po przekroczeniu jakiego wysięgu zadziała ogranicznik udźwigu żurawia o oznaczeniu 600 T z podwieszonym ładunkiem o masie 700 kg:

Using the diagram, determine beyond which working radius the rated capacity limiter will activate on the crane designated 600 T with a suspended load of 700 kg:Open full-size illustration
a
8 m

8 m

b
9 m

9 m

c
7 m

7 m

Correct answer

d
11 m

11 m

Why?

In the 600 T row, the rated capacity (udźwig) at a working radius (wysięg) of 7 m is exactly 700 kg. Beyond 7 m, the rated capacity limiter (ogranicznik udźwigu) should prevent any further increase in radius with this load. At 8 m, the permitted load is only 630 kg, so 8 m is already beyond the limit.
