Abstract

Ovaj završni rad prikazuje postupak konstruiranja preklopnog dohvatnika s minimiziranim najmanjim dohvatom. Dohvatnik se koristi za potrebe pretovara u zatvorenom skladištu, stoga se zanemaruje utjecaj vjetra. Dohvatnik se oslanja na betonsku podlogu preko sidrenih vijaka. Najveća nosivost iznosi 500 kg, maksimalni dohvat iznosi 4 m, dok je visina dohvatnika 3 m. Mehanizam promjene dohvata kao i okretanja dohvatnika je izveden pomoću vertikalne osovine, para radijalnih ležajeva i aksijalnog ležaja. Pogoni su izvedeni električni.
Završni rad se sastoji od: proračuna mehanizma za prihvat i dizanje, proračuna nosive konstrukcije i odabira i provjere pogonskog sustava.
Sva tehnička dokumentacija i 3D modeli su izrađeni u programskom paketu Solidworks 2015.

Abstract (english)

This undergraduate thesis presets the construction procedure of the articulated jib crane with minimized minimum reach. The crane is used for transshipment of unit loads in closed warehouses, hence the influence of the wind can be disregarded. The crane is connected to the concrete base by anchor bolts. The maximum capacity is five hundred kilograms, the maximum reach is four meters and the height of the crane is 3 meters. The reach changing mechanism is derived from a vertical shaft, a set of radial bearings and an axial bearing. All driving mechanisms are electrical.
The thesis consists of: calculation of mechanisms for acceptance and lift, calculation of load-bearing structures and selection and review of driving mechanisms.
All technical documentation and 3D models were made in the software package Solidworks 2015.
