Abstract

Ovjesne dizalice su često sredstvo unutrašnjeg transporta komadog materijala. Razne mogućnosti konstrukcijskih izvedbi omogućuju im prilagodbu prema prostoru u kojem se ugrađuju. U prilog im ide i relativno velika nosivost, koja se može postići pogodnim projektiranjem nosača i vitla, kao i jednostavnost rukovanjem. U ovom radu su opisana postojeća rješenja ovjesnih dizalica, te su dane njihove glavne geometrijske i radne karakteristike, koje su kupcu prilikom kupnje takvog proizvoda najinteresantnije. Nakon toga slijedi proračun i dimenzioniranje nosive konstrukcije za dizalicu koja se giba uzduž, po donjem pojasu nosača koji je u vijčanom spoju s okvirnom konstrukcijom koja je temeljnim vijcima spojena u betonski pod hale. Napravljen je proračun komponenti voznih kolica za pogon i prijenos snage. Naposljetku je izvršena provjera stabilnosti i čvrstoće nosive konstrukcije te čvrstoća zavara. Konstrukcijsko rješenje je dobiveno projektiranjem u AutoCAD-u, te je napravljen glavni sklopni crtež, potom sklopni crteži nosive konstrukcije i voznih kolica, te radionički crteži svih nestandardnih dijelova.

Abstract (english)

Hoist systems are often used as material transporting solution in closed areas. A variery of design makes them adjustable to the geometrical area requests. Their advantage is high capacity, achived by properly designed trolley and support structure, also as ease of use. Here are described existing solutions of electric chain hoists, available on market and their working and dimensional characteristics, which are most interesteting to the purchaser. Further is done calculation for steel structure support for chain hoist, which rides longitudinally on lower belt of steel support, which is connected by bolts to the frame structure connected also by bolts to the concrete area ground. Calculation has been made for all trolley components, including power transmission parts. Finally is done calculation of safety for frame structure, regarding deflection and solidity, also as safety of welds. Design has been done using AutoCAD software and by it has been made main assembly drawing, assembly drawings of steel structure and trolley and at least workshop drawings for all non-standard parts.
