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

established its own manufacturing facility but also began independent research and production of hydraulic breakers and
attachments under the registered Ramtec brand. Though the companies once shared a collaborative connection, their product
lines have since evolved separately, now offering distinct and unique solutions.
