Marine Gears Delivers Haley Units For Three Vessels At Main Iron

Marine Gears, Inc., Greenville, Miss., recently delivered six new main propulsion Haley gear units and six Haley auxiliary drive units to Main Iron Works, Houma, La.

These gears were installed in three new vessels operated by G & H Towing of Galveston, Texas. The three vessels and their owners are: M/V Deacon, Suderman & Young; M/V Jupiter, ITT; and M/V Andrew K., Bay-Houston Towing.

The three vessels each received two Haley RV2835 marine reverse reduction gears of the flywheelmount clutch series. These gears, equipped with Haley 35TB650 clutches, are matched with 16-cylinder EMD engines and rated 1,950 hp at 900 rpm with a ratio of 4.5:1.

Each vessel also received two Haley Auxiliary Drive Units (HADU 12) used as speed increasers with 1,200 rpm input and 1,800 rpm output.

The purpose of these auxiliary units is to drive hydraulic pumps which power the towing winch and capstan. These auxiliary units are powered by mounting them to the front end of the crankshaft of the 6-71 Detroit Diesel generator pack- age. The HADU 12 units are designed with an air pneumatic disc plate clutch allowing for remote operation from pilothouse or aft deck.
