BRADEN WINCH

Braden Winch Company of Bro- ken Arrow, Okla., is now marketing its second generation of planetary hoists. Designated the CH Series, they have capacities from 15,000 to 23,000 pounds and are offered with four motor options—three single- speed motors and the Braden two- speed motor. The motors have im- proved starting efficiencies to 84 percent, and the two-speed unit can be shifted on the fly.

The following features have been incorporated in CH Series: lower minimum motor speeds—200 rpm for the single-speed motors and 150 rpm for the two-speed motor; anti- friction bearings throughout, which improve the hoists' starting efficien- cy (less motor) to 93 percent; longer life; longer duty cycle; smoother spooling; reduced noise level; im- proved brake valve stability; im- proved brake clutch assembly; and

The accessibility of motor bolts, brake discs, wire rope anchor, and fill, level, and drain plugs makes the

CH Series hoists easier to service and maintain. Maximum inter- changeability of parts results in low- er parts inventory to service all hoists in the series.

CATERPILLAR

Caterpillar has introduced the

V925 lift truck designed to meet the needs of the worldwide container- handling industry. The V925 has 75,000 pounds of capacity when equipped with a container-handling spreader for moving and stacking fully loaded 20- to 40-foot contain- ers at dockside, rail yards, and transfer terminals. It is the largest in the Caterpillar Lift Truck prod- uct line.

Among the V925's special fea- tures is the oil disc brake system.

The multiple disc design provides significantly more braking surface than standard shoe-type or dry cal- iper disc brakes. The result is excel- lent response and extended brake life, up to 15,000 hours under con- tinuous operation. Dual 21:00 by 35 drive tires and single 18:00 by 33 steer tires, the largest offered in the industry for this size class, provide a large contact area and low ground pressure for long life.

The V925's Cat planetary power shift transmission—currently used in large Cat wheel loaders—has four speeds forward and reverse for the varying conditions required in con-

Deck Machinery

Crosby Group—continued inches. The sheaves are an ideal choice for original equipment in self-unloading systems and as re- placements.

McKissick sheaves are forged from controlled quality 1035 carbon steel which provides excellent weld- ing and flame hardening character- istics. All incoming steel is tested by chemical and spectrographic meth- ods to insure consistently high qual- ity.

Steel sheaves have excellent flexi- cializes in custom designed blocks to any specification, oil field blocks, crane and hook blocks, overhaul balls, swivel hooks, and snatch blocks, as well as many other prod- ucts. Western manufacturers sheaves and sleeves, wood and steel blocks, and cargo blocks and fit- tings, just part of its extensive prod- uct line. National's product line in- cludes steel swaging sleeves, duplex sleeves, swage buttons and furrules, as well as swaging presses in capaci- ties from 500 to 3,000 tons.

ULCC you will find Pusnes steam deck machinery. Looking closer at the windlass on any of these large tankers you will notice up to 1,000- hp disc brakes used to drop the anchors under finger tip control.

Visit a semisubmersible on a drilling station and you will find Pusnes mooring systems for chain, chain- wire combo, or all-wire and moored in depths up to 3,500 feet. Systems for greater depths and hostile envi- ronments are under development today.

Pusnes also manufactures moor- ing equipment for smaller coastal ships, barges, tugboats, off-shore

Pusnes is part of "SUBTECH"

Norway, a firm developing complete diving systems which employ diving bells, underwater vehicles, bell winch systems, divers gas recovery systems, external life support sys- tems, and the "Hyperbaric" satu- rated divers lifeboat. Concern for offshore personnel resulted in the development of "Pudes," the con- trolled extendable protected gang- way for dry evacuation.

Pusnes has a joint venture compa- ny in Japan, Nippon-Pusnes, and both are represented in the U.S. by

Alden Electronics produces the world's most extensive line of weather map recorders and weather satellite systems. It's a line developed to satisfy the needs of any user.

Alden systems are aboard the largest tankers, military vessels of many nations, ocean- ographic research ships in virtually every ocean, and oil platforms inshore and off. But they are also in use among fishing fleets, coast guards and other commercial interests- even individual yachtsmen.

That's because Alden offers more receiver features and a complete range of models that allow each user to select the optimum unit. Our larger systems, for example, pro- vide direct satellite receiving capability which is not available from other manufacturers

Alden weather facsimile systems are used by more than 80 different governments, and many of their broadcasts are made with Alden facsimile trans- mitters. So, you can be certain that every one of our receivers is properly designed and fully reliable.

All these systems utilize Alfax electrosensitive paper for the sharpest and most easily-read charts. And both the equip- ment and paper are sold and serviced worldwide.
