Our products combine the best aspects of ZF and of FH propellers. This is because both were a part of Masson-Marine at some point in their history. Our propellers are assembled in France or in China, depending on the geographic location and the wishes of our client. The electric controls are easy to install and combine high flexibility and maximum safety (as for example through automatic reduction of the propeller pitch in case of overload conditions or excessive towing warp strain/ winch load). Come-home devices are efficient and easy to use if, for any reason, the controls should be damaged. The propeller hub is a monoblock part, thus preventing all risks of ingress of water into the propeller blade positioning system.The assembly is particularly simple. Removal of the blades does not require the propeller shaft to be moved, even inside a nozzle. In the MMS version, the servo cylinder is attached to the output coupling flange of the gearbox; this design allows very fast access when the piston rings have to be replaced, for instance. The system is simple and requires minimum maintenance: all components are automatically lubricated by the hydraulic circuit. Masson-Marine offer a range of controllable pitch propellers for professional applications and continuous operation. We have inherited this activity from France Hélices. In fact, MM took over their activity in this area. In order to provide better service to our clients, and to extend our business, we maintain permanent efforts in research and development of our systems, thanks to our design department. Each project and every order undergoes a comprehensive case-specific study.
