Abstract

Razvoj užadi došao je do te mjere da se vrlo precizno može odrediti u kojim uvjetima primijeniti određenu vrstu užadi. U eksperimentalnom dijelu ispitivanja uspoređuju se svojstva užadi iste strukture od dva različita proizvođača. Od svakog proizvođača nabavljeno je po deset metara užadi u četiri različita promjera. Cilj ispitivanja je utvrditi da li proizvođači užadi zaista isporučuju užad definiranu prema propisanim normama i međusobno usporediti kvalitetu proizvođača. Ispitivani tipovi užadi ujedno su i najčešće korišteni tipovi užadi za dizala u cijelom svijetu. U radu je dan pregled povijesnog razvoja užadi i njihove primjene. Pored toga opisana je struktura te tehnička svojstva užadi koja se danas najčešće koristi u dizalima za prijevoz ljudi i dobara.

Abstract (english)

Evolution of ropes has reached the point where you can get precise determination of which rope to use in certain situations. In the experimental part of this paper, ropes of the same structure are compared from 2 producers of elevator ropes. Four rope diameters are included for this experiment and every rope has 10 meter length. Main objective of the experiment is to determine if producers really deliver ropes defined by written norms and to compare quality between 2 producers. Tested ropes in this experiment are also the most used elevator ropes in the world. In this paper is described history of development of elevator ropes and their application. Aside from history examination, structure and technical properties of elevator ropes which are mostly used for transportation of people and goods today are described.
