Ferry Capitain, other Company of the group CIF, designs and manufactures girth gear. Our expertise has afforded us a place amongst the world leaders in the cement industry and other heavy industries. CMD, with the cooperation of Ferry Caqpitain, offers a turnkey service including analysis of your installation, calculation and definition of products, manufacturing, testing, assembly on site and after sales and maintenance assistance. All of the above are subject to scrutiny in terms of an internal quality assurance plan.

In 1831, a royal ordinance granted Auguste Capitain the right to establish an iron-ore crushing operation, consisting of a mill driven by a hydraulic wheel, along the banks of the Marne River in Bussy, near Joinville, in the heart of the Haute-Marne region of France.  In 1835, after the construction of a blast furnace, daily production of cast iron reached 1,500 kg.

In 1901, the foundry equipped itself with a four-tonne open-hearth furnace enabling the manufacture of cast steel components.

Throughout the last century, major investments were made to reinforce and increase the machining capacity of the mechanical workshop, through to the 1980s, when the installation of a gear cutting machine with 12-meter diameter capacity signaled the arrival of Ferry-Capitain on the large open gearing market.

FERRY-CAPITAIN is the leading supplier of grinding mill components to the mining industry for several decades now. With trends to larger mills and a desire for gear driven solutions, the holding Groupe CIF invested heavily to strengthen FERRY-CAPITAIN´s position in the forefront of manufacturing technology for cast and machined components

FERRY CAPITAIN equates to 30 years of excellence in gear design, manufacturing and installation for heavy industry.

FERRY CAPITAIN mainly produces straight, helical and double-helical tooth gears.

Every year, FERRY CAPITAIN delivers approximately 150 pairs of large gears for a wide range of applications.

FERRY CAPITAIN designs gears according to the main international standards, ISO, AGMA and DIN.

FERRY CAPITAIN is a member of the AGMA and ARTEMA and participates in the development of AGMA and ISO design standards.
The drawings are produced directly in 3D in TOPSOLID.
