Question #535
An important criterion for assessing hook wear is:
Istotnym kryterium zużycia haka jest:
a
a crack
pęknięcie
b
widening of the hook throat
rozwarcie gardzieli haka
c
a reduction in the cross-section of the load-bearing part
zmniejszenie przekroju w części chwytnej
d
all answers are correct
wszystkie odpowiedzi są porawne
Correct answer
Why?
When inspecting a hook (hak), check for cracks, widening of the throat (gardziel haka), and loss of cross-section in the load-bearing part. Each defect can weaken the hook, so all the listed criteria matter. A hook without cracks can still be unsafe if it is excessively opened or worn.
