Title:DesignandApplicationsofTelescopicAttachmentBarinTowerCrane
Introduction:
Theadvancementinconstructiontechnologyhasledtothedevelopmentofvarioustypesofcranes,includingtowercranes.Towercranesarecommonlyusedintheconstructionindustryforliftingandtransportingheavymaterialstogreatheights.Toenhancetheirfunctionalityandversatility,towercranesareoftenequippedwithattachmentssuchasjibs,booms,orluffingarms.Amongtheseattachments,thetelescopicattachmentbarplaysavitalroleinextendingthereachandefficiencyofthetowercrane.Thispaperaimstodiscussthedesignandapplicationsofthetelescopicattachmentbarintowercranes.
