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 trace back to our role as an agent for Ramtec Finland in China's Northern region. In 2010, as one of Ramtec Finland's esteemed agents,
we embarked on a new journey by establishing Ramtec CN in China to promote the prestigious Robi brand products from Ramtec
Finland. By 2013, Ramtec CN proudly set up its own manufacturing facility, dedicating itself to the research and production of hydraulic breakers and
attachments while registering the distinctive Ramtec brand series products. Although our paths have diverged, with both companies producing distinctly different products today,
our shared history of collaboration remains a testament to our joint legacy.
