GVA series which are specially designed for progress-minded shipbuilding. For a long time they will be the standard for sturdy, lightweight and safe twin input/single output gearboxes.It has some properties: heavy rigidity of the integrated thrust bearing, security of connecting tooth mesh in all-load service by a self-supporting gear housing, and safe connecting of all torque transmitting parts and reliable control devices. The pinions are case-hardened and ground .Specifications of various types of these gearboxes are approved by the latest standard rules of classification societies. So they have a wide range of application.
