Question #653

The maximum mass of the load lifted at an angle β of 65° must not exceed:

Maksymalna masa podnoszonego ładunku przy kącie β wynoszącym 65° nie może przekraczać:

a
12000 kg

12000 kg

b
9000 kg

9000 kg

c
6000 kg

6000 kg

d
lifting is prohibited

nie wolno podnościć

Correct answer

Why?

Lifting at β = 65° is prohibited because it exceeds the maximum sling leg angle from vertical (kąt odchylenia cięgien od pionu) of 60°. The 6000 kg limit applies only up to 60°. Simply reducing the load mass does not permit lifting at 65°.
