Haley DRV 1711 Hydraulic Gear Unit

Haley Marine Gears realizes that quality of product must be complimented with equal service quality to survive in today's ultra-competitive market. The company was recently involved with a job which allowed it to exhibit its prowess on both ends, resulting in a highly satisfied workboat customer in New York. One of CR Harbour Towing & Transportation's (Glen Cove, N.Y.) towboats was recently pulled from service so that it could be re-powered with CAT 3512B marine diesel engines. Chris Roehrig, CR's president, wanted to get the right propulsion gears and have them installed correctly the first time, thus averting more time out of service and lost money. As an original equipment manufacturer, Haley Marine is the largest exclusive manufacturer (800 to 6,000 hp) of marine propulsion systems in the U.S., engineering top-of-the-line gears, clutches and couplings for marine applications. The company is also known for its good reputation for on-site repair service, which is quick and technically correct. "Haley Marine made the gears fit the vessel, and offered us a warranty on the customized gears," Roehrig said. "We needed the gears to fit in a certain space. They made the gears fit, and made them work." "It's something we do every day for our customers: get them the right gears in the right place, and as quickly as possible," said Kyle Haley, president, Haley Marine Gears. For the CR Harbour repower, Haley Marine provided two Haley DRV-1711 hydraulic gear units, rated for 1,500 hp at 1,600 rpm at a ratio of 6.02:1. The clutches were externally mounted wet disc clutches and carburized, precision-ground single helical gear elements, which were designed, engineered and manufactured by the company. The couplings were Haley highly resilient torsional couplings.
