Amarillo Gear

Has The

Right Angle

On Bow And

Stern Thrusters

Where right angle gear drives are being used in bow and stern thrust- ers, reliability is an important fac- tor. Amarillo Gear Company's drives have reliability built in—have had since 1936.

Our spiral bevel gear drives give de- pendable power transmission from motor or engine to thrusters with maximum efficiency. These right angle drives are available in 12 sizes, from 20 through 750 HP, and in a wide range of increasing or decreas- ing speed ratios. Hollow or solid shaft models are available for use with light or heavy thrust loads.

They put real muscle in barge pumps, too.

Amarillo Gear has a large family of satisfied customers. We'd like to make you a member of the family.

Artist's concept of Litton Industries' newly-designed tug-barge system which will transport bulk materials on the Great Lakes. Combined with the tug, the complete system will be 1,000 feet long—the biggest size permitted by the Poe Lock passage at Sault Ste. Marie and the largest pusher-type tug-barge system in the world.

Litton Industries has announced plans to produce and operate the first of a new-type tug-barge sys- tem designed for transporting bulk materials on the Great Lakes.

The unique, self-unloading, 15,- 000 horsepower tug-barge system, with a deadweight cargo capacity of approximately 52,000 long tons, will be the largest pusher-type tug- barge system operating in the world. It will carry iron ore and pellets, coal, limestone and grain between Great Lakes ports in the

United States and Canada.

The huge barge is being pro- duced at Litton's Erie Marine di- vision in Erie, Pa. Litton recently awarded a contract for approxi- mately $3.5 million to Halter Ma- rine Services, Inc. of New Orleans,

La., for construction of the world's largest pusher-type tug boat. The contract with Halter includes in- stallation by Halter Marine of the main engines, propellers and other equipment furnished by Litton.

The powerful tug will be 152 feet long and 54 feet wide, with twin 7,50O horsepower engines driving separate controllable-pitch propel- lers. Litton and Breit Engineering

Inc., also of New Orleans, are co- designers of the tug.

The Litton barge, 975 feet long, 105 feet wide, and 28*4 feet maxi- mum draft, will be 1,000 feet long when attached to the tug—the maximum length permitted by the new Poe Lock passage at Sault

Ste. Marie.

A large notch in the barge stern will accommodate the bow of the pushing tug. The newly-designed rigid connecting system, invented by Breit Engineering, will permit the tug and barge to function as a»n integral unit in all kinds of weath- er, including high seas. The con- necting system will also permit quick and easy separation for add- ed operational flexibility and main- tenance.

The self-unloading system uses a boom that reaches 200 feet over either side of the barge to discharge materials at rates up to 10,000 tons per hour into storage piles or shore side hoppers. The barge can be loaded at pocket docks as well as sites using conveyor systems.

Litton's new tug-barge system is expected to provide significant economies over conventional tug- barge units. It also offers several major advantages over self-pro- pelled cargo ships, including: lower operating costs, lower con- struction costs, and greater oper- ational flexibility. The new tug- barge system is designed to per- form with the same speed and turnaround time as conventional bulk cargo ships.

Litton Industries, headquartered in Beverly Hills, Calif., is a major multinational corporation specializ- ing in products, systems and serv- ices for business, defense, marine, industrial and professional mar- kets.
