The E-Crane Opposed Barge Haul System

E-Crane International

USA has developed a

Vector Opposed Barge

Haul System utilizing two W.W. Patterson

Winches. A stand alone

PLC supplied by

Richmond Engineering controls two VFD drives providing controlled barge movement. Two opposed winches, each with a rated running capacity of 17,000 lbs and a starting line pull of more than 40,000 lbs are the heart of this system. Each winch is driven by a 15 hp, 0 to 1,800 rpm, 460V – 3 Phase – 60 Hz, inverter duty electric motor. www.ecrane-usa.com

New Anchor Handling & Escort Winch Design

Markey Machinery

Company, Inc. introduced a new dual purpose hydraulic winch designated the type

DYSDS-52WF-250MT, fea- turing a unique design opti- mized for anchor handling as well as escort/assist servic- es. Each drum measures 24- inches barrel diameter, 48.5-inches barrel width, and 68- inches flange diameter to carry 750 ft of 10-inch circum- ference soft line in eight layers. The upper drum’s two hydraulic motors allow 12.3MT pull and 60m/min speeds with Markey Render/Recover controls for Escort /Assist services. The lower drum’s four hydraulic motors produce 250MT pull and up to 10m/min speeds with dedicated controls including pushbutton freewheel mode. Both drums are outfitted with two stainless steel braking drums rated for a minimum holding force of 227MT at the top layer. www.markeymachinery.com

Sealion Shipping Orders Rapp Winches

Rapp Hydena’s TWS- 11000 winch was installed in early 2009 aboard the DP-II class dive-support vessel

Toisa Sentinel, fol- lowed by another aboard the Toisa

Conqueror in May.

Both winches handle 3500m of 29mm diameter wire, line pull is 53 tons first layer at speed step 1 with a cor- responding line speed of 33 metres per minute. Both winches feature tension control. Rapp’s in-house manu- factured WDU-10000 series gearbox, with a trio of motors, powers the winch. Even if one motor fails, con- tinuous use of the winch is assured and gear reduction aids in extending motor service life www.rappmarine.com
