rope races

English to Serbian Tech/Engineering Mechanics / Mech Engineering

Poštovane kolege,

Potreban mi je ovaj termin na srpskom jeziku u kontekstu priručnika za dizalice:

Drum is made of seamless tube, and its surface is processed into rope races according to different model, such as right-handed rotation or left-and-right handed rotation.
Rope guide has rope races inside.

Hvala svima!
