Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer - specialized in the industrial robotic field, 3D designer, industrial designer and, 3D modeler.
For some of my projects, I'm also doing the physical prototype too.
I'm doing product design, industrial design, reverse engineering, ideation, etc.
I have over 15 years of experience working on various systems/devices across multiple industries, from concept to launch.
1- I could design a similar device with some differentiations in order to avoid patent infringement (if you check their website, on lower-left corner is the notice "The Extractor LLC, Patent pending")
2 - we'll have to discuss the technical details/parameters of the hydraulic unit and the accessories
3 - there are also room for some improvements and enhancements of the system
4 - would be useful if you know the basics of the components (ex. they uses a Honda engine, etc)
For any more questions, we could chat here, including the whole details of the project, final price, time frame, deliverables, etc, etc...
Regards
Bogdan
