Chris-Marine initiated five decades of excellent cooperation with MAN Diesel & Turbo in 1963. Back then the impact wrench ABC34 was developed upon request from Burmeister & Wain (B&W) in Copenhagen, Denmark. The wrench was used to loosen bolts on B&W 2-stroke engines hydraulically. Later Chris-Marine got to specialize in grinding & milling solutions for maintenance of engine block & components, starting with our classic grinding equipment for maintenance of cylinder exhaust valve and seat.
Chris-Marine has over several decades developed and adapted products for Caterpillar, MaK Engines. Today, Chris-Marine has available solutions for the maintenance tasks involving machining of surfaces in the cylinder liner, the engine block and the cylinder cover. Some Chris-Marine machines are used by Caterpillar during production of new parts for MaK engines.
