Hi,
I am a mechanical engineering student. I need help with my final year project. We are automating a portable crane which is used to lift weights of about 300Kgs max and are usually transported over a distance of about 5 to 6 mts at a time. We thought of using a simple reduction motor for the lifting and lowering of the weight. The current application uses a 6mm metal rope which i obviously too thin for the application and wears out very often. I need to design a new rope. Can anyone tell me the procedure to calculate the rope dimensions and if possible provide me with a list of the standard ropes available.

These sites may be of interest to you and would help you in your selection.

For cranes, a SF of 4 is usually taken while designing crane wire ropes. Multiply your load with this and select the appropriate size for your system. There is no need to design your own rope, it is always better to select from what is available, rather than reinventing the wheel.

Google is an undergraduate engineering student’s best friend and a graduate student’s life saver. Some times you need to get creative with the search terms to find what you need. If you stick with it you can eventually find something.

Try this:

Also try google for wire rope catalogues; there are a good number of them on the web.

Let me know if it helped.

I agree, but you have to get creative with your searching methods. Switch the words around. Include some words and neglect others. Use "insert word here" to look for pages that contain that exact phrase or word. You can also add site:edu or site:net site:org to help. There are a lot of engineering courses that address engineering problems. To see only educational posts, try site:edu. Google also has a scholarly search. Go to google.com and click on more>> above the text bar and then click on scholar. Google is very helpful if you know a couple of tricks.
