Logan Clutch Corporation  

Logan CH Series Heavy Duty Clutches and Brakes for Z-Drives, Render-Recover Deck Winches and Heavy-Duty Gearboxes:

Logan CH / HPC Series clutches are heavy-duty, multiple disc wet or dry, and ideal for Azimuth Thrusters / Z-Drives, bow or tunnel thrusters, heavy-duty gearboxes, render-recover and mooring winches, deck winches, FiFi gearboxes and more.

CH / HPC Clutches are air or fluid actuated, available in seventeen (17) sizes, and designed for wet or dry operation. Torque ranges from 49,000 lb-in (5532Nm) up to 2,880,000 lb-in (325424 Nm). Maximum allowable pressure ranges from 120 psi (8.3 bar) to 360 psi (25 bar). Pressure varies for wet or dry operation. Modified standards are available for specific OEM applications. Made in USA. 

Logan SAE / DIN mounted Direct Drive power take-off (PTO) clutches are self-contained, air/fluid activated, and designed to mount between the live power take-off (PTO) of an engine or auxiliary attachment such as a hydraulic pump or pump drive.  The heavy-duty, corrosion resistant design is ideal for auxiliary marine drive applications. ABS agency approved.

PTO Clutch Applications:

• Single and Multi-Station Pumps

• Mobile or Stationary Auxiliary Drives

• Connect/Disconnect Direct Drives

• Winches, Reels, Hoists, Bow and Tunnel Thrusters, Winch Drives

Advantages:

• Reduces fuel consumption and CO2 Emissions by engaging drives and pumps only when required

• Faster Starts: Lowers horsepower draw and cranking power required during machine start-up by disconnecting the hydraulic system from the engine

• Reduced ambient noise through intermittent use of pumps and equipment

• Cooler running hydraulic systems: Heat is generated whenever oil dumps from high to low pressure without producing work. Disconnecting the PTO Clutch reduces the destructive effects of heat – lowering maintenance costs and hydraulic oil requirements

• Extends the life of drive systems and components, since the drive is engaged only when required

Logan Front of Engine PTO clutches act as a connect-disconnect power source for pumps & drivelines mounted to the front of your engine.  Logan clutches reduce fuel consumption, lower emissions, and improve pump life by engaging pumps only when required. They are also ideal when system troubleshooting requires the hydraulic system to be disconnected from the main or auxiliary engine while in operation, or underway. 

Logan Universal Front of Engine PTO’s incorporate an integral flexible coupling to mitigate from torsionally active diesel or gasoline engines. Using a clutchable PTO off the front of an engine provides practical space savings and an additional power source connection for marine hydraulic pumps, drivelines, and auxiliary drive applications.

Clutches can be furnished with an engineered bracket design, driveline shaft arrangement, or as a universal coupling, driveline and foot mount arrangement for common applications.

• Extends the life of drive systems and components

Marine Applications:

Logan Air / Fluid actuated Bell Housing PTO’s mount directly to a diesel engine’s flywheel and are used as a connect / disconnect drive for main propulsion, or for generator sets which control fixed displacement or variable displacement pumps. Logan PTO’s are suitable for tug boats, workboats, fishing boats, jet boats, patrol boats and pleasure craft.

Typical applications include:

• Generator sets

• Deck and cargo winches

• Bow thrusters

• Drag net reels

• Deck pressure washers

• FiFi pumps Logan PTO Features:

• Air or Fluid actuated for maximum torque capacity

• Self adjusting disc pack – minimizes slippage • Fast engagement – Quick release

• Eliminates Mechanical Linkages, Hand Levers, and Yokes
