When Canadian towing and barge services provider Island Tug and Barge encountered problems with the mechanical clutch system on one of its tugs, it turned to Logan Clutch to provide a solution. Island Tug, based in Vancouver, British Columbia, offers towing and barge services, including ramp-equipped deck barges, aggregates and general cargo, as well as cable installations. The companys towing services extend to the Pacific Rim, and it also has facilities on Canadas eastern seaboard. Island Tug had been running two generator sets on the tug Island Scout. These ran pumps for the main hydraulics and bow thrusters off the back of the engines. In order to do this, both engines were equipped with conventional, mechanical lever actuated PTO clutches to drive the pumps. The problem was that these clutches started to fail during full rev/min engagement. Generator sets normally run at 1,800 rev/min and cannot be slowed down to allow for clutch engagement. These failures were creating frequent

Logan CH 1050 series clutches proved to be just what was needed when New York-based Reinauer added fast and maneuverable articulated tug and barge units to its fleet. Reinauer Transportation Companies, based in Staten Island, New York, is a leader in the US maritime petroleum and chemical transportation business. Established in 1923 by Bert Reinauer, the company successfully weathered the Depression and the war years, and has continued that trend through the past several decades. In the 1990s, Reinauer demonstrated that it could adapt to the stringent regulatory changes imposed by the Oil Pollution Act of 1990, completely revamping its fleet by moving forward with innovative double-hulled vessel designs. These innovations manifested themselves in the form of articulated tug and barge (ATB) units, of which there are now a total of 17 in the Reinauer fleet. The most recent series of ATBs added to the Reinauer fleet were delivered by Senesco Marine, of North Kingstown, Rhode Island. There

World Wide Fittings, located in Chicago, specializes in the manufacture of steel tube and pipe fitting components, supplying over 150 million components annually to domestic and foreign markets. Everything they manufacture meets ISO, SAE and any customer-specific standards. Dan Holt, Plant Manager, with recent success with his National Acmes and Logan Clutches, decided to retrofit a model B Davenport screw machine with a Logan Clutch Hi-Lo Retrokit, and CS2001XT controller. The retrofit met and exceeded all expectations. The easy-to-install, air-operated Logan clutch eliminates the constant adjustment problems of the original Davenport mechanical clutches, roll clutch, band brake, and linkages. Engagement and disengagement now are smooth and positive. The new quick-stop, power-applied brake prevents machine coasting. With the fast-acting clutch, World Wide now has the ability to run the machine at full index speed for a greater part of its cycle. Dan Holt reports that he has seen anincrease

The conversion involved adding a new Logan LCT Bell Housing clutch on to the 21 flywheel output of the 3512s with an integrated Centa torsional coupling. The flange output of the clutch was connected by a shaft to the motor
