2GWH Gearbox
ADVANCE 2GWH (twin engine parallel) marine gearbox is developed based on GW series gearbox technology and is suitable for main engine dual input single output transmission box according to customer needs. 2GWH series (twin engine parallel) marine gearboxes are widely used in various types of ships with dual main engine layout, such as bulk carriers, oil tankers, container ships, fishing boats, work boats, special ships, etc.
2GWH Marine Gearbox
2GWH series (twin-engine parallel) marine gearbox has the functions of dual input and single output, clutch, speed reduction, torque transmission and withstand propeller thrust. The front end of the output shaft can be equipped with a CPP oil distributor.
The gearbox transmits the power of two diesel engines with the same steering direction to the propeller through dual power input and single power output. The PTO output can be clutched or not clutched according to the needs to meet the requirements of different customers; the gearbox operation control mode is pneumatic control or electric control.
