hello,I need 140T Demag AC140 DWG blocksmy Email: hamzatranslog@gmail.com 

Hello souhila2018, you could try : BIBLIOCAD , grue demag ac 140 but you have to register, maybe not really a problem.It looks like you will find the lateral elevation and plan views but not all the others view necessary to do a real lifting study.On the other hand if you can use a "generic" crane you could use : GROVE_GMK5130-2.dwg available here in the CAD/BIM Blocks library and this file of mine includes all the views, boom lengthes + diagrams if I remember well.I had done this file with the help of the official PDF file.With this crane you can also use the MANITOWOC-GROVE software available on the internet : GMK OUTRIGGER PAD LOAD CALCULATOR that is really usefull.Eventually ask for a PDF that I have done that gives all the necessary instructions for that software.
