the mechanics of the “scoop” that the garbage is loaded into would need a complete redesign to cut much noise..as any of the trucks Ive ever seen produce as much noise standing still moving the garbage into ithe big bin as they do whilst traveling.
Im all for a complete re do
Yes, the hydraulics that run the loader and compactor make a lot of noise. I think you’d need to go to some type of electric screw mechanisms to be really quiet.
But that’s a whole ‘nother engineering project.
