Hello community,I am working on a workshop/production drawing for a vessel and I need a functional 3D CAD model (preferably a .dwg) of a Davit-Arm Manhole Cover mechanism with Cover conforming to DIN 28124-4 and DIN 28124-3. Specifically Type H, d2 = 670 mm.Does anyone would be willing to share?Thanks Zoran

Hello zoranob, I can see that the model that you want H for horizontal is not complicated but some dimensions are not included in that page 1 of 4 like the dimensions b, d10, l1, l2, l3, details X, Y, Z, etc...Those dimensions should indicated in the rest of the norm.These are not complicated 3D solids to elaborate.

Hello zoranob, I have placed in the CAD/BIM Blocks library the 2D and 3D AutoCAD file :MANHOLE CLOSURE DIN 28 124.dwgI'm still waiting fot the additional dimensions to finalize the 2D and 3D entities.

I would be grateful – surely other users would be too. I can send both required standards in full to your email address – DIN 28124-4 and DIN 28124-3. They are not large PDF files. My email address is zoranob@yahoo.comThanks and best regards,Zoran Obrenoviæ

Hello zoranob, I have already placed in the CAD/BIM Blocks library my 2D and 3D file :I'm just waiting for the dimensions that I send you to your personnal e.mail.See the picture here enclosed.P.S. I had found the DIN norms to draw everything.
