WELCOME TO MY BLOG

Hi and thank You for visiting my blog.

This blog is about my professional work, projects I have been working on, and some funny and interesting things about mechanical engineers. On these pages You can find some of my projects, as I work for army and I am not able to enclose all projects I have been working on.

My most recent designs You can find in posts below.

For more interesting projects You can follow labels, such as:
- aircraft engine blades


- aircraft parts


- wind tunnel models

...etc...

You can download some of my models, posts with files for download are labeled free model download.

or You can go to INDEX page and search through list of all projects on this blog.

Info about me is on ABOUT ME page, where You can see my professional CV and some info about my skills and professional knowledge.

For all questions about my work, projects, blog or job offers contact me over e-mail or Skype. E-mail form and Skype Add Me link are on CONTACT ME page.

For those who are interested in learning new stuff about Siemens NX program I made NX TUTORIALS page, where I will post some tips and tricks about how to use NX more efficiently.

Tower crane 3D model (free CAD download file)

designed in Siemens NX6

This is unfinished 3D model of Tower Crane, I designed as much as I could just by looking at images of tower cranes on internet. I over dimensioned most of model, as at first i had idea to try to make it in plastic. Most of cable work is unfinished as I do not have enough info about cable system. If anyone have informations I need to finish this design, please contact me.
NOTE: In this design I didn't use real profile dimensions for steel beams, but in .prt files profile dimensions are editable in sketches.
NOTE: Design is based ONLY on photos of tower cranes i found on internet so do not take it seriously.

EXPLANATION: fore jib connector part as it is now is designed only to hold constrains in assembly.


So far assembly of this model consist of 20 parts (more will come as model get more details):
  1. apex
  2. apex rear conector (connection between 'apex' and 'rear pendant counterjib conector')
  3. cabin
  4. cable conector (connection between two 'rear cables' holding counterjib)
  5. counter weight segment
  6. crane body segment ground base (ground segment)
  7. crane body segment (repeating segment)
  8. crane climbing segment 
  9. crane cabin segment 
  10. crane jib - base (jib segment connected to 'crane cabin segment')
  11. crane jib last (end of jib segment)
  12. crane jib main (repeating jib segment)
  13. motor (motor behind cabin)
  14. fore cable (repeating cable that hold jib)
  15. fore cable conector (connection between `apex` and `fore cable`)
  16. fore jib connector (unfinished part, connection between 'crane jib main' and 'fore cable')
  17. rear cable (repeating cable that hold 'counter weight segment')
  18. rear pendant counterjib conector (connection between 'rear cable' and 'counter weight segment', and 'rear cable' and 'apex rear conector')
  19. trolley (trolley with cage and long cable)
  20. trolley sc (trolley without cage and with short cable)
  21. ASSEMBLY (part only, due to some error I was not able to make it in STEP format)

  6. Zdravo Ivane,
    Prvo cestitam na ovako dobro uradjenom poslu. Vizuelno to izgleda odlicno.
    Samo steta, sto kran nije racunat pa da modeliras prave dimenzije komponenata, jer si ostavio mnogo vremena za ovaj posao. Onda je to mogao biti projekat koji se mogao unovciti.
    Ali svaka cast na tvom entuzijazmu i volji da ovako nesto modeliras.
    Pozdrav
