Ceiling jib crane

U ovom završnom radu bilo je potrebno konstruirati konzolni granik uz dane zahtjeve. Prije svega, nosivost granika iznosi 0,5 t, radijus konzole je 3 m, dok je visina prostorije 4 m. Također, potrebno je bilo zadovoljiti i brzinu dizanja koja iznosi 10 m/min, brzinu vožnje vitla 15 m/min i brzinu rotacije granika od 2 okr/min. Kako je granik namijenjen za skladište logističkog centra, uz navedene parametre o kojima je trebalo voditi računa, bilo je poželjno osloboditi prostor na tlu. Pa je onda tako i tema ovog rada stropni konzolni granik. U uvodnom razmatranju analizirani su principi postojećih konstrukcijskih izvedbi te su ponuđena dva koncepcijska rješenja od kojih je jedno izabrano kao optimalna varijanta. Nakon uvoda slijedi proračun mehanizma za dizanje u skladu s važećim europskim normama za transportne uređaje, potom slijedi oblikovanje i proračuni vitla i konzole te mehanizma za okretanje granika. Za prikaz konstrukcijskog rješenja izrađen je 3D model i tehnička dokumentacija koja je priložena u završetku rada. Za navedeno je korišten programski paket SolidWorks 2017.The assignment of this final thesis was the design of a jib crane while taking into consideration the given requirements. The load capacity of the crane is 0,5 t, the radius of the crane is 3 m, while the height of the room is 4 m. Also, requirements of lifting speed of 10 m/min, winch speed of 15 m/min and rotational speed of the crane of 2 rpm must be met. Since the crane's intended use is in a logistics centre warehouse, additionally to the given parameters it was preferable that the space on the ground remained free. Therefore, the name of this thesis is ceiling jib crane. Introduction analyses the principles of existing design solutions and two conceptual solutions are offered of which one was selected as the optimal solution. After the introduction follows the calculation of the lifting mechanism in accordance with the current European standards for transportation devices, then follows the shaping and calculation of the winch and cantilever as well as the mechanism for rotating the crane. For displaying the design solution, a 3D model was produced along with the technical documentation which is attached at the end of the thesis. The stated was done in SolidWorks 2017 software package
