8.4 t
8,4 t
Correct answer
b
8.0 t
8,0 t
c
6.0 t
6,0 t
d
4.0 t
4,0 t
Why?
The tag gives a working load limit (dopuszczalne obciążenie robocze, DOR) of 8.4 t for the sling (zawiesie) at β up to and including 45°. The 6.0 t rating applies above 45° up to 60°, so it is not the maximum DOR here. In the diagram, β is the angle of a sling leg from the vertical.
