Abstract

Zbog potrebe povećanja sigurnosti u poljoprivrednim poslovima na snazi je zakon koji
nalaže da svi traktori proizvedeni nakon 1983. godine moraju imati ugrađenu neku vrstu zaštitne
konstrukcije.
U sklopu ovoga rada prikazana je kategorizacija zaštitnih konstrukcija namijenjena za
traktore od 1.5 do 4 tone. Nadalje, detaljno je proučen pravilnik TPV 310, kojim se definira
način opterećivanja zaštitne konstrukcije. Od tri predstavljena koncepta okvira, odabire se
najpogodniji prema listi zahtjeva. Donesen je zaključak da će se konstruirati dvije zaštitne
konstrukcije: prva za manje traktore do 2t i druga za traktore od 2 do 4 t. Nakon konstruiranja,
provjeravani su pomaci zaštitne konstrukcije te dali dolazi do narušavanja vozačevog prostora,
određenim pravilnikom TPV 310. Nakon toga, na obje konstrukcije provjerila su se kritična
mjesta na konstrukciji, zavari i vijci.
Na kraju je izrađen 3D model za obje zaštitne konstrukcije, kao i pripadajuća
dokumentacija.

Abstract (english)

Due to the need to increase safety in agricultural operations, there is a law in force
that mandates that all tractors manufactured after 1983 must have some type of protective
structure installed.
As part of this paper, the categorization of protective structures intended for tractors
from 1.5 to 4 tons is presented. Furthermore, the rulebook TPV 310, which defines the
method of loading the protective structure, was studied in detail. From the three presented
frame concepts, the most suitable one is selected according to the list of requirements. It was
concluded that two protective structures will be constructed: the first for smaller tractors up to
2t and the second for tractors from 2 to 4t. After construction, the movements of the
protective structure were checked to see if there was a violation of the driver's space, specified
by the TPV 310 regulation. After that, critical places on the structure, welds and bolts were
checked on both structures.
At the end, a 3D model was created for both protective structures, as well as the
associated documentation.
