The project is almost complete but please increase the price and specify the capacity to carry, it is vital in order to complete its last phase and for me to finally submit.

Hello Aly
How much is the height from the yard to the floor?

Please explain how to build a product with maybe patent protection? And...the development of the product will take not les than 2 months ant will cost just for the engineering not les than 10.000 Euro. So? Do not be so naiv please! However we speak about mashinery and transportation ot peaple, the requirements are not joke,

This product is only available in the UK. I'm trying to build this in my house for my son. It will not be a commercial product, just something that I can contract its design and build. My intention is to have three contests: 1) Engineering Drawing, 2) Engineering Design, including materials, electro-hydronic mechanizm and operations, and 3) Build.
This context is for the first step, the drawing only

Do u need electro-hydraulic operation?

This is not a DIY project. This is serious engineering with liabilities and patent infringement possibilities.
I agree with both comments before me which should explain why this is not a pre-pay as well.

How is this a contest? It looks to me like a reverse engineering job. Something that is already available. You might want to check if there is a patent on this product already.

An interesting project, but it is worth a lot more than $100!

Compressor Valve Improvement
I have several designs for a compressor valve that I have been working on. I am looking now to manufacture based on a numnber of tests made. However, I have 2 designs that I need to decide to finalize. I would like to get good engineering feedback on the best option that will ensure no leakage and the longest operational running hours. These valves will run in a compressor and need to run for 16000hrs and longer.

I have two simple spur gears that I want design a lock mechanism for them. The lock shall be engaged with one of these two spur gears and prevent rotation in both directions (both CW and CCW). The lock mechanism shall be triggered easily with a signal or a servo or similar method upon the request of operator to lock gears. The lock mechanism should be able to released easily and with simplicity.
