DECK

MACHINERY

A REVIEW

Faster, more efficient cargo han- dling reduces costs and increases profit opportunities for all vessel owners—inland, coastal and deep- draft. To satisfy the changing needs of these cost-conscious customers, manufacturers of deck machinery and cargo handling equipment are continually improving existing equipment and introducing new models. Lighter weight, increased capacities, safer designs, automa- tion, increased speeds and corro- sion resistance are just a few of the areas of advancement.

We surveyed the major designers and manufacturers of cargo han- dling equipment to learn of their latest developments as well as their proven products. The following re- view on cargo handling is based on the replies we had received as we went to press.

Brochures and literature de- scribing all of the products manu- factured by the companies featured in this article are available free of charge.

AMHOIST

Write 21 on Reader Service Card

American Hoist & Derrick Com- pany, St. Paul, Minn., designs and builds lifting equipment for every type of energy project. Standard marine cranes come in capacities of 30 to 3,000 tons; larger sizes can be custom-engineered for specific applications. Amhoist products range from huge barge- and ship- mounted revolvers to the Sea Horse pedestal crane for materials han- dling aboard offshore oil rigs.

Lucker Pullers—linear hydrau- lic "cable grip" devices—can be used singly or combined in differ- ent ways for an endless variety of lifting, pulling, and positioning tasks.

Amhoist also manufactures

American stiffleg derricks in many configurations and sizes for use on barges, ships, platforms, or gantries.

Representative of Amhoist's ma- rine revolver cranes is the M-56 supplied to Bouygues Offshore, a

French marine construction firm.

The crane, with a maximum ca- pacity of 1,200 tons on the main hook, is mounted on Bouygues Off- shore's new combination pipelay- ing/derrick barge, the BOS-400.

The all-electric machine has 235 feet of boom, an auxiliary hook ca- pacity of 350 tons, and a whip hook capacity of 75 tons. It will be ready for operation in early 1984.

APPLETON MARINE

Write 22 on Reader Service Card

A bulk commodities processing vessel working in the Mississippi

River is employing three identical

Appleton Marine winches to main- tain vessel position during cargo transfers between supply barges and ocean-going bulk carriers.

The electrohydraulic, self- contained winches have line pull capable of up to 140,000 pounds at infinitely variable speeds of 30 fpm. The Appleton winches can operate as automatic constant- tension units or can be switched to manual operations as required.

Both modes can be achieved at the winch or at a central control room.

In addition, the winches provide greater user flexibility in that both the line pull and line speed are in- finitely variable from zero to the maximum in any combination.

Appleton (Wis.) Machine Com- pany's Marine Division designs and manufactures a wide range of marine cranes, winches, and deck equipment that are in accordance with the requirements of the USCG and the major classification so- cieties.

Appleton has also added hydro- graphic launch and recovery sys- tems to its extensive product line which includes offshore mooring winches and anchor windlasses, oceanographic winches, and deck fittings, knuckleboom cranes, div- ing support winches, and mooring systems control consoles.

BEEBE INTERNATIONAL

Write 23 on Reader Service Card

Beebe International, Inc., Seat- tle, Wash., offers a series of high capacity air chain hoists that rep- resent an important advance in the air powered hoist industry.

These unique air chain hoists range in capacities from 10 to 50 tons and are powered by a radial piston air motor which provides increased reliability and longer life.

Primary applications for the

Beebe hoist include BOP handling systems for the drilling industry and individual hook mount units for the shipbuilding and ship re- pair industries.

The hoists are very lightweight and compact in design. They also are fitted with lifting lugs which permit easy installation and relo- cation of all available models. The 7/8-inch chain on all models allows for fewer chain falls than other conventional hoists.

An inherent advantage of air powered units is that they may be operated in explosive environ- ments and the motor will not overheat and burn up.

The horsepower and lifting speed of Beebe's air chain hoists provide more power per unit weight than other hoists. Each of the units is also available with hydraulic motors.

Beebe also recently introduced a low-profile electric barge winch available with a 25-ton dog hold- ing capacity. It has a line speed of 50 feet per minute. The simple de- sign reduces component wear and tear, and also provides for major parts replacement without moving it. The unit can be controlled from the deck or remotely from the pilothouse. 24 Maritime Reporter/Engineering News
