Abstract

Tema ovog završnog rada je koncipirati i konstruirati električna kolica za penjanje po
stepenicama. Glavni cilj uređaja je olakšati transport teškog i nezgrapnog tereta ne samo po
ravnom terenu već i stepenicama. Kolica moraju biti konstruirana po pravilima ergonomije
kako bi bila se korisnicima olakšala manipulacija tereta i kolica tijekom postupka svladavanja
stepenica te kako bi se osigurala sigurnost korisnika tijekom tog opasnog posla. Uređaj mora
biti pogonjen električnim motorom te sadržavati bateriju kako bi ostao autonoman. Rad
započinje provedbom analize tržišta, definiranjem funkcijske strukture te morfološke matrice
na temelju koje se razrađuju koncepti. Odabran je optimalan koncept s kojim se išlo u daljnju
razradu, proračun kritičnih dijelova te izradu 3D CAD modela. Naposljetku je još napravljena
i tehnička dokumentacija uređaja.

Abstract (english)

The topic of this final thesis is to design and construct an electric stairclimbing cart. The main
goal of the device is to facilitate the transport of heavy and bulky loads, not only on flat surfaces
but also on stairs. The cart must be designed according to ergonomic principles to ease the
handling of both the load and the cart during stair navigation while ensuring user safety during
this demanding task. The device must be powered by an electric motor and equipped with a
battery to maintain autonomy.
The project begins with a market analysis, followed by defining the functional structure and
developing a morphological matrix, which serves as the basis for concept development. The
optimal concept was selected for further refinement, including calculations of critical
components and the creation of a 3D CAD model. Finally, the technical documentation for the
device was also prepared.
