MCD4000

Twin Disc pioneered the slipping clutch concept more than 30 years ago and today offers a full line of timetested, field-proven Marine Control Drives (MCDs).

The new series of MCDs offers distinct operating advantages for any vessel requiring highly accurate positioning or extreme slow-speed maneuverability while splitting main engine power to operate high-powered FiFi pumps.

• Extraordinarily modulated power achieves propeller speeds below engine idling speed
• Unique design and manufacture allow for intentional clutch slipping to regulate propulsion speed
• LD (Low Dissipation) slips up to engine idle speed for maneuvering and DP operation*
• HD (High Dissipation) slips up to rated engine speed with the capability to dissipate all heat generated by that when power dividing*
• Optional high-power PTO to drive auxiliary equipment
• Used in conjunction with azimuth thruster systems
• Best alternative to controllable pitch propellers (CPP)
• Smooth, gradual propeller speed change resulting in improved maneuverability
• Safer and easier vessel control during slow speed maneuvering and docking
• Adjustment of propeller speeds below engine speed rating
• Divides the power from the main propulsion engine to eliminate the need for auxiliary engines
• Delivers an instant response when required
• Bearing calculated for high universal joint angles at maximum power
• Dynamic positioning (DP) capable
• Emergency “come home” device per classification requirements
• Easy, in-engine room maintenance; no need for diver assistance or to dry-dock the vessel

* Slip at any engine speed can be done based upon specific application criteria. Twin Disc’s expert application team will help customize your MCD selection to any desired operator requirement.
