Hi there,
I'm a mechanical engineer with over 15 years experience in designing, modeling, prototyping and effective manufacturing of different products, ranging from consumer goods to alternative energy systems.
Lately I've worked in the pumps field, designing and manufacturing peristaltic(hose) and piston pumps for food industry.
I know how to fit all the element into the trailer, keeping in mind the ergonomic factor (the components should be placed in such way to allow easier maintenance) and same time to be functional with minimum hydraulic loses.
I could design your trailer based on your sketches/drawings, and I'll deliver the 3D model and components in different CAD format(ipt/iam, iges, stl, step, obj, etc), 3D pdf so you'll be able to open the model into the regular Acreobat Reader, and some renderings.
