Weight of cabin is 600 kg and allowable load is 500 kg. Chain Wheels Diameter is 290 mm. What is the weight of counter weight?

Attachment 46597

Sounds like homework. How did you work it out and what did you come up with?

if you can, please answer the question

We won't do your homework questions for you.
You were given the assignment for you to learn.

If you come up with your own answer and post it for us to critique that is within reason.

If you have some SPECIFIC questions that you couldn't find or didn't understand, we may help with that.
But this is your assignment, so show us you have at least attempted to complete it on your own.

Thank you.

It's not a homework. I am mechanical engineer and I need a help to solve this problem. It's a real mechanism not a homework or exam.

Half the load capacity plus the total weight of the load should give you the weight of the counter balance. However other factors like where the lifting rig is actually placed and cable sizes, have to be considered and that's not apparent from your attachment. Also the composition of the "chain wheels" is a significant factor, so my assumption is based on a straight line from the center of the cabin. Like an elevator.

More specific info would lead to a greater accuracy.

Thanks for your help. I attached more picture about wheel chain connection. Chain is 20B. Please ask everything you need for a best solution.Attachment 46602

Nice pictures, but they yield no pertinent information. A blueprint would help you figure out the details of what you need to know, if indeed this is an actual machine, and not course work with given details to arrive at an answer.

I have guided you to how the weight can be calculated, and if you have the details then you can calculate the answer for yourself. It's patently unfair for me to do that work, and not get PAID.

Back to YOU.

It's actual machine and given details as I said in first but I don't know how can I calculate the weight of counterweight and don't know how use details, I'll thank you if you guide me about this.
