FAQ :
Question A : There is also a Ramtec Robi in Finland, what is the relationship between Ramtec CN and the one in Finland?

gained, Ramtec CN inaugurated its manufacturing facility in 2013, venturing into the research and production of hydraulic breakers and
attachments under our own revered Ramtec brand. While our collaborative journey with Ramtec Finland was foundational, today's offerings
from both entities are distinctly unique, reflecting their evolved paths.
