Logan Bell Housing PTO's For Typical Applications

In this example, the customer has developed a skid mounted drive system, with a Heavy-duty side load requirement. Logan Engineers specified a Generation II LC-314 due to its spread bearing design. The Logan Gen. II handles 50% more side load than a standard Gen. I 314 Design. Also, the Gen II does not require a pilot bearing, which is prone to failure in heavy duty side-load applications.  

The Logan Gen. II LC-314 transmits a maximum 4420 lb. ft. of torque (5993 Nm) @ 435 psi. (30 bar), providing ample safety factor in this application which only requires 3094 lb. ft. (4195 Nm).

Logan Direct Drive PTO Clutches Enhance Bow Thruster

Steering a commercial boat or large yacht can be similar to driving a heavy car with bad brakes. Its difficult to stop, and response to the rudder is slow. This poses no problem in the open sea, but it can be real challenge to maneuver the vessel in a congested marina or when docking. This is where a bow thruster comes in. A bow thruster consists of an open-ended tube that runs through the underwater sections of the hull near the bow and perpendicular to the keel. A propeller mounted at some point inside this tube can rotate in either direction. The helmsman selects the rotational direction and actuates the propeller. As a result, the bow thruster sucks a solid stream of water in one end of the tube and forces it out of the other, pushing the bow sideways and augmenting the rudder to make steering more responsive. Two Props are better than one Traditional single propeller systems generate thrust by accelerating water in the axis of the propeller shaft. However, the water discharged

Logan self-adjusting, hydraulically actuated Bell Housing Power Take-Off (PTO) clutches have been standard equipment on OEM marine and mobile equipment for over 18 years. Thousands of Logan units are in the field, operating on airport snow blowers, highway and airport marking and runway rubber removal equipment, and more recently trailor mounted waterblasting equipment. Logan vs. Mechanical PTOs The advantage of the Logan Clutch is its ability to engage and disengage the water jetter hydraulically, through push-button activation, eliminating the use of a mechanical hand lever or yoke type clutch engagement system, which dates back to the early 40s. Smooth, Logan softstart engagement eliminates clutch downtime due to over and under adjustment. And since the Logan clutch is self-adjusting, clutch engagement is smooth and consistent after hundreds of hours of use. The mechanical clutch requires the operator to hand engage a clutch, which opens up the opportunity for untrained operators

Logan Self-Adjusting Bell Housing PTO Clutches Now available for Field Retrofit into 2005 and older Oshkosh H-Series Blowers

April 11, 2018 Category: Mobile, Snowblowing

Logan self-adjusting Bell Housing PTO clutches have been standard equipment on all Oshkosh H-Series Blowers manufactured since 2005. Hundreds of Logan units are in the field, operating at a high level of excellence and readiness for major U.S. Airports such as Chicago OHare, Boston Logan, Cleveland-Hopkins, Buffalo Airport, and more. The Logan Advantage: The advantage of the Logan clutch is its ability to engage the snow blower drivetrain hydraulically (for factory blower trucks), and pneumatically (for pre-2005 H-Series field retrofits). This eliminates the use of a mechanical hand lever or yoke type clutch engagement system, which requires frequent mechanical adjustments many times during snow removal conditions, which leads to downtime and inconsistent operation. For example, mechanical clutches that were improperly adjusted, often led to disc wear and eventual clutch failure requiring the truck to be taken out of commission, requiring many hours to pull the blower trucks drivetrain
