Development of a crane load software application for electric driven overhead travelling bridge cranes in accordance with SANS 10160-6:2010

[摘要] ENGLISH ABSTRACT: Electric driven overhead travelling bridge cranes (EOHTC) form a vital part of industrial plantswhere heavy objects require moving. Overhead travelling cranes aid in production by allowingan uninterrupted work process on the ground while heavy loads are moved to their requiredlocations.Various factors need consideration in determining the loads induced by an EOHTC on itssupport structure. In order to design such a support structure, the designer must understandand take into account the various loads that the support structure will be subject to during itslifetime.The procedure for determining the loads induced by the EOHTC on its support structure is laidout in the SANS 10160-6:2010 code of practice. This document was published in June 2010and as a result very few worked examples exist to test the coherence of the procedure.This thesis presents an investigation into the procedure for determining the actions induced byoverhead travelling bridge cranes adopted in the SANS 10160-6:2010 code of practice. Theinvestigation was conducted by developing a software application to automatically determine thenecessary crane actions needed for the design of the crane support structure, given certaininput parameters. The motivation behind this was to have a tool that can calculate the craneinduced loads automatically. And by developing such a tool the procedure given in the code ofpractice is better understood.The Java programming language was used to code the calculations with an object orientedprogramming approach (OOP). NetBeans, the integrated development environment fordeveloping with Java was used to generate the required graphical user interface of theapplication. In addition, a Microsoft Excel calculation sheet was also developed for the purposeof comparison and verification.Whilst developing the software application, it was found that the model for the acceleration ordeceleration of the crane was specific for four wheel cranes only. This model was then extendedto accommodate eight and sixteen wheel cranes and incorporated into the algorithmarchitecture of the application. The application was successfully completed and verified using benchmarked examples.
