Hydraulic gearbox Dong-i DMT100IV for marine engine
The Dong-i DMT100IV marine transmission, made with high-rigidity aluminum resistant to marine environments, is designed to be lightweight and efficient. It weighs 150 kg and has an oil capacity of 7 L. This model allows remote control via a shift valve, both mechanically and electrically, and enhances engine efficiency through a 14° bevel gear. It facilitates gear maintenance by allowing adjustment of the engine installation space. Developed under the ISO9001 quality system and compliant with DNV and ISO6336 standards, this transmission is ideal for high-speed propulsion systems, both with surface drives and propeller shafts. Its efficient design optimizes space usage in vessels.
