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.

Description

• 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.*
• MD (Medium Dissipation) slips up to a defined engine speed below rated speed, allowing power dividing up to that speed/power.*
• 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.
• Optional PTI for secondary propulsion power source, up to 7,600 Nm torque on MCD output shaft.
• Used in conjunction with azimuth thruster systems.
• Best alternative to controllable pitch propellers (CPP).

*Twin Disc’s expert application team will help customize your MCD selection to the desired operator requirement.
