Deck Machinery (Blohm + Voss—continued) rigging the hook on the slings for heavy lifts, a trolley is arranged at one side of the derrick. Its capacity is 25 tons, and it can operate in all topping angles of the derrick. For additional information on the HLM units, Circle 17 on Reader Service Card 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 Whatever Your Mission, Alden Weather Chart Recorders Offer Options In Size But Not In Quality 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 Series 9519: Full-size 18" weather charts, plus orbiting and geo- stationary satellite data with analog- digital signal pro- cessing and image enhancement. electrosensitive paper for the sharpest and most easily-read charts. And both the equip- ment and paper are sold and serviced worldwide.

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. For more information on Braden hoists, Circle 18 on Reader Service Card JERED BROWN BROS. Jered Brown Brothers is a major supplier of deck machinery and oth- er marine equipment worldwide. Products include anchor windlasses and capstans, non-magnetic mine- sweeper deck machinery, cranes, steering gears, elevator systems, main thrust bearings, and line shaft bearings. Jered equipment is speci- fied on FFG 7, CG 47, LSD 41, LHD 1, MCM 1, T-AO 187, T-5, and CVN Class vessels and many other com- mercial ships. In addition to providing equip- ment on new ship construction, Jered provides spare parts and maintenance on deck machinery in service. Jered has engineering draw- ings and parts for equipment manu- factured by American Engineering, C.H. Wheeler, Baldwin-Lima-Ham- ilton, and Jered Industries. For additional information, Circle 31 on Reader Service Card 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- tainer handling. The transmission can be shifted at speeds up to 5 mph without potential damage or short- ened life. Another feature is an inte- gral steer axle/counterweight. The entire rear section oscillates about the main frame, providing low rear profile for superior visibility and lateral stability. The V925 cab, with pilot-oper- ated hydraulic controls, provides for operator comfort and high perfor- mance under full work demands and extended shifts.
