This paper describes the structural design of the lifting frame designed for handling ameliorating waste concrete pipes. It demonstrates one task solved in the subject Construction practice directed for the students studying specialization: Teachers of technical education at the University of Hradec Kralove. In order to determine the stress distribution at the lifting frame, a theoretical analysis of the problem was performed. 3D computer model of the lifting frame was created subsequently. Computer analysis of generated 3D models was performed using the finite element method and the software Autodesk Inventor. The article presents some of the results obtained through the mentioned software such as the distribution of equivalent stress in the individual sections of the frame and the corresponding deformation of the expected static load capacity. KEYWORD: Construction problem; structural analysis; computer model; stress analysis of frame. International Conference on Industrial Technology and Management Science (ITMS 2015) © 2015. The authors Published by Atlantis Press 953 Specially designed lifting frame for the mobile crane may serve as another option of handling concrete pipes. This lifting frame is the main output of here investigated problem. Figure1. 1-concrete tube, 2-welded chain, 3-caliper The mobile crane is displayed on Figure 2 on the right and the mounted lifting frame in the middle of the figure. Lifting frame is hanging on chain slings and connected by a crane hook with rope. On the left of the image is situated upright the concrete pipe. Figure 2. View of the crane with lifting frame and tube. 1-mobile crane, 2-chain hinge 3-lifting frame, 4-concrete pipe, 5-circular hole in the pipe, 6-circular opening in the housing
