FAQ :
Question A : There is also a Ramtec Robi in Finland, what is the relationship between Ramtec CN and the one in Finland?
Answer A : The origins of Ramtec CN can be traced back to its initial role as an agent for Ramtec Finland in Northern China. In 2010, one of their agents,
established Ramtec CN to promote Robi brand products from Ramtec Finland throughout China. By 2013, Ramtec CN not only
established its own manufacturing facility but also began independent research and production of hydraulic breakers and
attachments under the registered Ramtec brand. Although the companies once shared a collaborative connection, their product
lines have since evolved independently, now offering distinct and unique solutions.
