Twin input – single output gearboxes is often used when variable power to the propeller is required. The gearbox can be operated with one or two engines at the same time.

In vessel were extra reliability is required this is a good solution. The engines can either be placed in front or behind the gearbox. PTO’s for hydraulic pumps or shaft generator can be delivered.


The gearboxes are manufactured with following main components:
Cast steel gearbox housing
Input shaft arranged for flexible coupling
Hydraulic operated multi-plate clutch for secure and soft engagement
Gearwheels with hardened and ground helical teeth for silent operating

Hydraulic built in servo unit for secure propeller pitch setting
Output shaft with flange arrangement for propeller shaft coupling
All bearings of roller type with a low friction losses and long lifetime
Spherical roller thrust bearing with a low friction losses and long lifetime

All parts are made of the most suitable material qualities.
