10.0 t
10,0 t
b
8.4 t
8,4 t
c
6.0 t
6,0 t
Correct answer
d
4.0 t
4,0 t
Why?
The tag gives a working load limit (dopuszczalne obciążenie robocze, DOR) of 6.0 t for the sling (zawiesie) at β = 60°. The 8.4 t rating applies up to β = 45°, so it cannot be used at 60°. Despite the question's wording, the diagram measures β between a sling leg and the vertical.
