Abstract (Croatian)

Zadatak ovog diplomskog rada je konstruiranje mosnog granika za podizanje i premještanje teških vozila do 70 tona ukupne mase unutar industrijske hale pri čemu je predviđeno da se vozna staza granika oslanja na nosivu konstrukciji hale. Visina dizanja tereta je 12 metara, a potrebni raspon mosta iznosi 15 metara. Prihvat vozila ostvaruje se u četiri točke s rasponom od 3 do 5 metara po širini te od 6 do 10 metara po dužini vozila. Granik radi u poluteškim pogonskim uvjetima, te u zatvorenom prostoru pa se utjecaj vjetra može zanemariti. U prvom dijelu rada provedena je kratka analiza postojećih konstrukcijskih rješenja mosnih granika velikih nosivosti s ciljem odabira optimalnog konstrukcijskog rješenja za zadane projektne parametre. U drugom dijelu rada je za odabrano konceptualno rješenje proveden detaljan proračun elemenata za prihvat i dizanje tereta kao i analitički proračun nosive konstrukcije mosta i vitla prema navedenoj literaturi, te je izvršen odabir odgovarajućih pogonskih jedinica mehanizama za dizanje tereta, vožnju vitla i vožnju mosta. Na kraju je izrađen CAD model i potrebna tehnička dokumentacija.

Abstract

Main goal of this thesis is to design an overhead traveling crane for lifting heavy vehicles with the mass up to 70 t inside an industrial hall where it is predicted that rails are leaning on load-bearing structure of the hall. Required lifting height is 12 m and demanded bridge span is 15 m. Vehicle has 4 lifting points with width span ranging from 3 to 5 m and length span ranging from 6 to 10 m. Crane operates in heavy duty conditions and inside industrial hall, thus the wind load can be neglected. In the first part of the thesis, a short analysis of the existing structural solutions of high load overhead cranes has been carried out with the purpose of choosing the optimal structural solution for given project parameters. In the second part of the thesis, a detailed calculation of the load lifting element for the chosen conceptual solution has been carried out, as well as the analytical calculation of bridge and trolley load-bearing structure according to cited literature. In addition, the selection of corresponding load lifting, as well the bridge and trolley drive units has been made. Finally, a CAD model and required technical documentation were made.
