Logan Bell Housing PTO for Marine Applications

Logan Air / Fluid Actuated Bell Housing PTO’s

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, generator sets, auxiliary drives, Fi-Fi Pumps, and for fixed displacement or variable displacement pumps.

Logan PTO’s are suitable for tugboats, workboats, fishing boats, jet boats, patrol boats and pleasure craft.  Activation is simplified since Logan PTO’s are fluid or air-actuated, and self-adjusting, enabling remote engagement from the bridge or wheelhouse, and requiring no mechanical adjustment.

Bell Housing PTO's – 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.

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
• Drive flange SAE or DIN

Remote Actuation

Since Logan clutches are Fluid or Air operated, and self-adjusting, actuation from a control panel, wheelhouse or bridge is now possible.

Bell Housing PTO’s – Marine Jet Drives

Marine jet drives (waterjet propulsion) are powered by marine diesel engines ranging in size from 50 HP (38kW) to well over 500 HP (372kW), and are used as an alternative to propeller systems. Logan Bell Housing PTO’s act as a connect-disconnect from the diesel engine, and give OEM designers the flexibility required to adapt to all kinds of planing and displacement craft.

The City of Amsterdam Fire Department (Netherlands) – Jan van der Heyde IV

The 58 ft. / 17.6 meter Jan van der Heyde IV Fireboat is powered by Twin Volvo D13-500 Marine Diesel engines with No. 3 flywheels, and has a maximum speed of 15 km / 8 knots per hour. The vessel is equipped with two dedicated water pumps, driven by two Logan hydraulically actuated LC-211 PTO clutches providing a maximum torque transfer of 963 lb. ft. (1305Nm) @ 200 psi (13,8 bar), giving the vessel  443, 000 gallons / 1,680 m3 - cubic meters per hour of water pumping capacity.

Bell Housing PTO’s – Fire Fighting Systems

Fire pumps on Tugs and Workboats utilize Logan Bell Housing PTO’s as a connect-disconnect between the diesel engine and the fire pump. Activation is simplified since Logan PTO’s are fluid or air actuated, enabling remote engagement from the bridge or wheelhouse.
