Question #737

A reduction in the external diameter of the hoist rope may be caused by:

Zmniejszenie średnicy zewnętrznej liny nośnej może być spowodowane:

a
damage to the rope core

uszkodzeniem rdzenia liny

Correct answer

b
wear of the external surface

wytarciem powierzchni zewnętrznej

c
strand protrusion

wyciśnięciem splotki

d
all answers are correct

wszystkie odpowiedzi są prawidłowe

Why?

A damaged rope core (rdzeń liny) stops supporting the strands, which sink inwards, so the rope diameter decreases locally. Rope discard criteria list this as its own item, diameter reduction caused by core deterioration, and assess external surface wear separately. Strand protrusion (wyciśnięcie splotki) is a deformation of the rope, not a reduction in its diameter, so "all answers are correct" is wrong.
