FAQ:
Question A: What is the connection between Ramtec CN and Ramtec Robi in Finland?
Answer A: The origins of Ramtec CN trace back to being an agent for Ramtec Finland in China's Northern region. In 2010, as one of their agents,
we established Ramtec CN in China to champion the Robi brand products.
In 2013, Ramtec CN boldly ventured into its own manufacturing, pioneering the production of hydraulic breakers and
attachments, and proudly registered the Ramtec brand series. Although formerly cooperative partners, our product lines now
differ significantly from those of Ramtec Finland.
