Case references for DONG-I marine gearboxes showing their flexibility and full compatibility with existing ZF and other control systems across many different setups.
The DONG-I DMT5100 gearbox was supplied for a commercial marine application where reliability and smooth operation were key requirements. The gearbox was chosen due to its solid construction and its ability to fit easily into the existing engine setup without the need for complex modifications.
This case shows how the DMT5100 works well in real-world marine operations where equipment is used daily and must simply perform without issues.
The DONG-I DMT110 gearbox was delivered together with a John Deere 6090 propulsion engine for an aquaculture service vessel. The setup is used for daily operations where dependable propulsion and stable performance are essential.
The installation proves that DONG-I gearboxes are a good match for John Deere engines and are well suited for service vessels operating in demanding environments, where ease of operation and long-term reliability matter.
The vessel was equipped with a DONG-I DMTP 5100 gearbox with PTO output, a reduction ratio of 3.46:1 and an integrated trolling valve. The gearbox was delivered as part of a complete propulsion package, including a ZF control and manoeuvring system, exhaust silencer with ejector function, a 2” flushing pump, a new four-blade propeller, a complete keel cooling system and Rubber Design flexible mounts.
The result is a fully integrated and ready-to-operate setup designed for reliable marine operation
The John Deere engine was delivered as a complete package together with the DONG-I gearbox, using the PTO output to drive the vessel’s hydraulic systems. In addition, the engine is fitted with an extra PTO for future hydraulic requirements.
This case clearly shows that DONG-I gearboxes work seamlessly even when a ZF control and manoeuvring system is already in place. It highlights DONG-I as a flexible solution that fits into many different engine installations and system configurations without complications.
