Markey Electric Winch Markey Electric Winch Markey Machinery is preparing a new TES-40-75HP electric towing winch for shipment that will be installed on Har- ley Marine Services new Z-drive ship assist tractor tug M/V Robert Franco. The Þ rst item of two suites of deck ma- chinery speciÞ ed by Harley for both the M/V Robert Franco and itsÕ sister, the MV Ahbra Franco, the TES-40-75hp towing winch also Þ lls out MarkeyÕs electric towing winch line which now covers wire sizes between 1.25 through 2.5-in. The TES-40-75HP is a rugged single-drum electric towing winch with fairlead and warping head, designed speciÞ cally for use on ASD-tugs where aft deck space is at a premium. Its AC Variable Frequency electric drive sat- isÞ es a wide range of performance re- quirements. All electrical components comply with ABS, USCG, and IEEE-45 standards.The tow winch is part of a two-winch suite of equipment that also includes a Markey Model DEPCF-52- 75HP Class II Hawser Winch. Together, the two winches will share a single VFD drive panel and dynamic braking resistors, while having discrete wheelhouse con- trols for each winch. This reduces the impact of Òbelow-deckÓ equipment on available space, as well as system cost while supporting full functionality of ei-ther winch. The balance of the two ship sets is scheduled to ship in the near fu-ture. Both tugs are being built by Nich- ols Brothers Boat Builders of Freeland, Washington, with expected launch dates in the spring and summer of 2013. The tugs will enter service on the U.S. West Coast and will enhance Harley MarineÕs current ß eet of tractor tugs operating in the Tanker Escort and Ship Assist mar- kets. www.markeymachinery.com Deck Machinery & Cranes January/February 2013 46 MTRMTR #1 (34-49).indd 46MTR #1 (34-49).indd 461/30/2013 12:10:13 PM1/30/2013 12:10:13 PM
