Katalinic (Ed.), Published by DAAAM International, ISBN 978-3-902734- 08-2, ISSN 1726-9679, Vienna, Austria DOI: 10.2507/27th.daaam.proceedings.100 Abstract This paper deals with modeling and simulation of Hydraulic crane for load lifting in order to determine its dynamics, methods for lifting control and minimization of oscillations. The proposed procedure is modelling of crane with method of schematic design with inerconnected elements that represents crane parts, and its 3-d visualization. Simulations will be planned and applied for lifting motion of Crane’s Boom with hangind load. Dynamic analysis will be carried through simulations and solution of Euler differential equations of second order. Diagrams with results of main dynamic and kinematic parameters will be presented for main parts of crane as the solution results of the analyzed system. Based on these results conclusions will be presented. The aim is to find optimal lifting control process and dynamic behavior of crane which is important for motion planning, failure analysis and safety during work. Analysis will be done using modeling and simulations with computer application MapleSim. Keywords: Hydraulic Crane; Men Lifting; Dynamics; Vibrations; Control; modeling; simulations; 1. Introduction Many companies that work with Hydraulic cranes have difficulties dealing with load lifting due to oscillations and swinging of load, which can lead to safety problems. Hydraulic crane taken for study is also known as a Straight Boom Lift, Man Lift, Basket Crane. It is an elevated work platform that consists of a platform or Cabin at the end of a lifting system and is used to lift men and other load. It is important to find optimal procedure to lift the men and load in order to minimize swinging and oscillations. To do this, main kinematic and dynamic parameters of motion must be measured, which is difficult with instrumentation. Modelling and simulations helps determining crane’s behavior and search for * Corresponding author. Tel.: +377 44 503 577. E-mail address: mirlind.bruci@uni-pr.edu - 0693 -
