Abstract:V diplomski nalogi je predstavljen razvoj dveh različnih prototipov škripca za izvlek jeklenice iz gozdarskega vitla. Najprej je opisana analiza trga. Poiskali smo že razvite rešitve in iz posameznih sistemov izpostavili prednosti, ki smo jih nato združili v en sistem in s tem pridobili varnejši sistem z optimalnim delovanjem. Prvi prototip predstavlja nadgradnjo starejšega sistema, cilj je bil zmanjšati zunanje gabarite in izboljšati delovanje sistema, tako da bi bil primernejši in varnejši za uporabo. V drugem delu naloge smo razvili inovativno rešitev – neskončno vrtljiv škripec, gnan z elektromotorjem, ki prinaša dodatne prednosti. Oba sistema smo razvili, tako da sta pripravljena za izdelavo prototipov. V ekonomski analizi smo primerjali oba sistema in ugotovili, da je rešitev z elektromotorjem dražja zaradi uporabe slip-ringa in induktivnega senzorja. Vendar prinaša pomembne prednosti: večjo varnost, lažjo uporabo, boljši nadzor ter zanesljivejše delovanje.

Title:Design of a compact redirect duble pulley with a pre-brake and extraction
Abstract:This thesis presents the development of two prototype pulley systems for extracting a steel cable from a forestry winch. A market analysis was first conducted to identify existing solutions and highlight their advantages, which were then integrated into a single, safer, and more efficient design. The first prototype is an upgrade of an older system, aimed at reducing external dimensions and improving functionality for safer and more user-friendly operation. In contrast, the second prototype introduces an innovative, infinitely rotatable pulley driven by an electric motor, offering additional benefits. Both systems were fully modelled and prepared for prototype manufacturing. An economic analysis showed that the electrically driven solution is more expensive due to the use of a slip ring and an inductive sensor, but it provides significant advantages, including enhanced safety, easier operation, better control, and more reliable performance.
Keywords:pulley, extraction, safety, steel wire rope
