DLG Series
1113 – 110131 | 1,400 – 30,000 kW
Twin-input / single-output reduction gearboxes built for the largest commercial workboats, dredgers, and government support vessels — designed for high-torque dual-engine propulsion with integrated disc clutches.
Engineered for High-Power Dual-Engine Propulsion
Backed by over 80 years of REINTJES marine gearbox experience, the DLG series combines twin engine inputs into a single propeller output — built for the most demanding workboat, dredger, and government support vessel applications.
Twin-Input Configuration
Two engine inputs combined into a single output shaft, with identical input shaft heights for symmetrical engine room layouts.
High Torque Capability
Engineered to handle up to 30,000 kW of combined input power with integrated propeller thrust bearing and heavy-duty disc clutches.
Independent Clutch Control
Hydraulically operated disc clutches on each input allow single- or dual-engine operation, supporting redundancy and reduced-power running.
Continuous-Duty Reliability
Fabricated steel housing, case-hardened helical gears, and pressure-fed lubrication built for unlimited-hours commercial duty.
