20.500.12556/DKUM-76501 Konstruiranje traktorskega gozdarskega dvigala DOT 50ZK diplomsko delo Construction of DOT 50ZK tractor forestry crane Diplomsko delo opisuje konstruiranje traktorskega gozdarskega dvigala DOT 50ZK. Dvigalo je narejeno na osnovi kinematike Z dvigala. Dodana je nihalka na nihaji roki, s čimer se približamo nihajnim momentom kot so pri K dvigalih. Iz začrtanega 3D modela je narejen izračun sile dviga po zahtevanem momentu 50 kNm. Po izračunih je izrisan tudi diagram dviga na različnih dolžinah roke in preračun, kdaj roka preide v zlaganje. Iz 3D modela je pripravljena trdnostna analiza po MKE metodi. Na koncu je sledil še test dvigala, ki je potrdil preračune sile dviga roke na različnih razdaljah. Testirali smo tudi zlaganje dvigala. Diploma thesis describes the construction of DOT 50ZK tractor forestry crane. The crane is based on the kinematics of a Z crane. A pendulum on a swing-arm was added which got swing moment closer to the ones of a K crane. From the constructed 3D model, the lifting force was calculated based on a moment of 50 kNm. Based on previous calculations the diagram of lifting with different lengths of crane arm was made and it was calculated when to fold the crane arm. Out of the 3D model a strength analysis was done using MKE method. At the end the crane had to be tested to confirm the calculations of the lifting force at different lengths. We also tested the folding of the crane arm. traktorsko gozdarsko dvigalo konstruiranje dvigala moment dviga zlaganje dvigala MKE simulacija obremenitev rok tractor forestry crane construction crane lifting moment folding crane FEM – Finite Element Method loading simulation of crane arms true true false [N.
