Welcome to The ME2045 Group J Crane Project Blog page!


This entire site is to give a guide to Group J`s efforts to design a small portable crane for use in disaster relief before our final submission of work and our presentation.

Following our first meeting (See the Minute Meetings Topic for reference) the following positions have been allocated;

D.Scriven Project Manager
R.Sidhu Chief Designer
H.Singh Sall Finnance Officer
J.Sidhu Materials Specialist
R.Shukla Stress Analysis

For Our Progress up to date please see the Project Plan below and then head to the relevant topic and we hope you find our work interesting!

Summary

Project Summary

As a group we feel the project has been successful. If we were to carry out the same task again, we all agree that we would do nothing different. The crane itself was designed and tested very well. The group had a very wide variety of skills, the design engineers were very confident with CAD, and the mechanical engineers were very confident with the stress analysis. As a group we worked very well together from the beginning stages to the very end of the project. We set deadlines and met them almost perfectly every week, and with sometimes up to three meetings a week we were getting through the work at a very good rate. We as a group feel we could not have had a better group to work with.

During the duration of the project we faced some challenges. The hardest were probably the choice of material and the stress analysis. We had to change material a few times after stress analysis so the crane itself would not fail under stress. The choice of the design was also a difficult phase, we had a lot of different designs and different crane styles to choose from. Choosing the right one was a vital stage in the development of our crane, a bad choice would ultimately have led to a bad project.

Our final design was a very good design and we felt it was the best it could be, it was engineered to a safety factor of 1.5 and very different to most the other designs we saw. We felt a lot of the designs we saw had many more flaws than our own.

To summarise, the group was very happy with the whole project and the final design. We all feel that given the chance again we would not change anything and would carry out the task in the same way.

CAD Progress

The CAD is coming along!

As I said  the inital CAD prototype will be issued this friday to enable everyone to do their material caluclations. When we re-meet up after the easter the design will be updated and changed accordingly  and any other  changes needed/or liked  can be added.

For now, here are a few screenshots;
                                              
   The first drawing is assembly made usign blocks. It was motion-modeled to show how the crane would move. (Video Coming later!).

Next the blocks were turned into parts; Here  the two tower blocks were changed into a Box frame as shown above.


Here is a protoype of the  flanges  proposed to go onto the frame to enable the legs to be removed. The flanges from the other access points and corners arent shown here.

A mock of the clasp proposed to hold our two blocks of the tower together.

Project Progress - 05/04/2010

Alright Guys;

Just an update on the Project so far; Sorry  Havent been in contact for a week been off ski-ing!

I have just started doing the CAD model for our final design and hope to have it done by friday when I will send it round. I  have also started doing a step-by-step breakdown of the  crane  material calculations to make life easier ( and almost turn it into a set of questions) . The deadline for the material calculations is  the monday that we get back so we have plenty of time.?
 
Secondly; im going to start trying to tidy up the blogger. Not that there is anything wrong with it, but we seem to have posted everything onto the main page and not  used the smaller sub pages availble. Does anyone know how to relocate a post to one of the smaller subpages ?

Hope you guys are alll enjoying easter  and see you when we get back!
