Abstract

Ovaj završni rad se bavi analizom ergonomije rukovanja parangalom u sportskom ribolovu iz male brodice te prijedlogom konstrukcijskog rješenja koje olakšava obavljanje ribarenja. Parangal je tradicionalna ribolovna tehnika odnosno alat kojim se vrši ribolov pelagijske i pridnene ribe ručnim spuštanjem i podizanjem dugačkog užeta s više desetaka udica. Rukovanje njime je fizički zahtjevno, pogotovo prilikom samog spuštanja i podizanja iz mora.
Poglavlja završnog rada definiraju sve specifičnosti ribolova parangalom i analizu rukovanja, na temelju kojih se izvodi ergonomska analiza. OWAS metodom za procjenu radnih položaja su identificirani ključni problemi u tradicionalnom načinu rukovanja parangalom, te je predložen ergonomski povoljan položaj ribara prilikom obavljanja radnje.
Na temelju provedenih analiza i funkcijskih zahtjeva je predloženo konstrukcijsko rješenje za lakše i sigurnije rukovanje parangalom. Konstrukcija se sastoji od postolja s prihvatom, pokretačkog modula, modula za vođenje užeta, te kočnice. Prihvat konstrukcije za brod je napravljen tako da se jednostavno postavlja, te da nije potrebno bušiti brodicu. Prijedlog konstrukcije obuhvaća rješenja svih zahtjeva, kao što su: izmjena više parangala tijekom ribolova, ergonomski položaj pri ribarenju, mogućnost kočenja užeta parangala i sprječavanje zapetljavanja.

Abstract (english)

This final thesis focuses on the ergonomic analysis of handling a longline in small boat sport
fishing and proposes a structural solution to facilitate the fishing process. Longline fishing is a
traditional technique to catch pelagic and demersal fish by manually lowering and retrieving a
long fishing line with dozens of hooks. Handling this equipment is physically demanding,
particularly during the setting and hauling phases.
The thesis chapters define all the specific aspects of longline fishing and analyze the handling
process, forming the basis for the ergonomic assessment. Using the OWAS method for
evaluating working postures, key issues in traditional longline handling have been identified,
and an ergonomically favorable posture for the fisherman has been proposed.
Based on the conducted analysis and functional requirements, a structural solution has been
developed to enable easier and safer handling of the longline. The design consists of a base
with a mounting system, a drive module, a guiding module for the fishing line, and a braking
system. The attachment system is designed for easy installation on a boat without the need for
drilling. The proposed construction addresses various requirements, such as enabling multiple
longline changes during fishing, ensuring an ergonomic working position, integrating a braking
mechanism for the fishing line, and preventing entanglements.
