U ovome radu analizirano je optimiranje zamjene nosive užadi dizala na ovjesu 2:1. Svrha rada je optimizirati i pokazati ispravan način osiguranja postrojenja pri radovima koji su visokorizični za zaposlenike na istim i sličnim poslovima gdje postoji opasnost od lakših do fatalnih nesreća. U radu je opisan pristup osiguranja protuutega i osiguranja kabine od nekontroliranog pokretanja te upravljanje elementima koji se mijenjaju kako bi izvođenje radova teklo na siguran način i najmanjim brojem operacija. Zbog svoje posebnosti demontaža i montaža elemenata izvodi se ručno te je potrebno prije početka radova snimiti postojeće stanje objekta, jer se sami radovi odvijaju unutar voznog okna dizala, ali i svi ostali čimbenici prostora samog objekta utječu na radni proces kao što je visina građevinskog objekta, prilaz zgradi, širina komunikacijskih dijelova objekta, pristup krovištu i atmosferski uvjeti na zgradi. In this paper, the procedure for replacing the load-bearing steel ropes of the elevator on suspension 2:1 is analyzed. The purpose of the paper is to show the correct way of securing the facility during works that are high-risk for employees attending the same and similar jobs where there is a risk of minor to fatal accidents. The paper describes the approach to securing the counterweight and securing the cabin from uncontrolled starting, as well as the management of elements that change in order to ensure that the work is carried out in a safe manner. Due to its special nature, disassembly and assembly is performed manually, and it is necessary to record the existing condition of the building before starting the work, because the work itself takes place inside the elevator shaft, but also all other factors of the space of the building itself influence the work process, such as the height of the building, the approach to the building, the width of the communicating parts of the building, access to the roof and atmospheric conditions on the building.
