FAQ :
Question A : There is also a Ramtec Robi in Finland. What is the relationship between Ramtec CN and the Finnish company?
Answer A : The origin of Ramtec CN is intricately connected with Ramtec Finland. Initially, we were the agents for Ramtec Finland,
particularly in Northern China. In 2010, recognizing the potential, we established Ramtec CN in China to champion the Robi brand
products of Ramtec Finland. By 2013, we had evolved, setting up our manufacturing facility and embarked on producing our own
hydraulic breakers and attachments under the Ramtec brand. Though we once collaborated closely, today, our product lines are
distinctly unique and cater to different market needs.
