Cargo Handling

Equipment — Clyde (continued from page 27) of 290 short tons at an outreach of 40 feet.

One of Clyde's outstanding off- shore crane installations in recent years is aboard the giant semi- submersible, pipelaying / derrick barge Semac I. Heavy lifts on the vessel are accommodated by a

Clyde Model 42 Offshore Whirley with full electric drive, capable of lifting 500 tons overstern and 350 tons full revolving. Simple, rug- ged, and easy to maintain, that crane was customized and tailored to meet the huge barge's unique requirements.

Also installed aboard the Semac

I are three Clyde CPS-96 Sea

Whirlers™ with 75-ton main load blocks. Used for routine lifting, these full-revolving, fast-cycling, versatile pedestal cranes contrib- ute greatly to the vessel's mate- rial-handling requirements.

Clyde's AD™ winch, engineered in graduated sizes with stall pullx bare drum ratings from 150,000 to 350,000 pounds, is offered in single or multiple drum arrange- ments for anchor/pulling appli- cations. Features of the AD line include: anti-friction bearing de- sign ; alloy steel shafts, supported close to load centers; rigid, heav- ily braced framing and bearing housings; large-capacity steel drum; spring-loaded, air-released pawl; high-strength, multiple steel roller chain drive, splash oil bath lubricated; heavy-duty, sin- gle contracting band brake, air released; hand-operated air con- trols assembled in modular con- sole within easy reach of the op- erator; and air compressor and receiver.

Clyde also offers a constant ten- sion hydraulic tugger, the CTH

Models, with running pull/bare drum ranging from 10,000 to 54,- 000 pounds. The CTH tugger hy- draulic pump and motor combi- nation can be driven by either a

TEFC continuous rated squirrel cage electric motor or diesel en- gine.

A 180-page, full-color catalog is available from The Crosby

Group, a Division of Amhoist, which is comprised of Laughlin®,

Lebus®, McKissick, National, and

Western. Together they manu- facture every conceivable kind of fittings and accessories for cargo handling and other applications, including forged fittings, hooks, blocks, sheaves, pulleys, load binders, chain, etc. The catalog describes all of the products of all divisions in full detail with photos, detailed drawings, all measurements, and full specifica- tion charts.

One of Crosby's newest prod- ucts is Spectrum Chain, said to be the first color coded chain line.

Available in working load limits of 850 through 39,900 pounds and sizes of 14 to % inches, Spectrum provides instant chain grade rec- ognition and excellent anti-cor- rosive properties. It is available in four different grades — Spec- trum 3, 4, 7, and 8 — each color coded for easy identification.

A specially developed polyester powder is bonded to the chain surface by the use of electrostatic equipment, then heat treated to produce a tough, corrosion-resist- ant surface. The coating will not peel; clean handling and longer storage life results.

Crosby links and rings are man- ufactured in a complete line of sizes and types for almost any application, with working load

THE 80s

What are your first priorities when you specify ship cranes: high efficien- cy, adaption to extreme Arctic conditions, broad flexibility, ease of maintenance, ability to take heavy and/or bulky unit loads, a reliable service organization, or...?

The Hagglunds range of cranes and cargohandling equipment can satisfy the most varied requirements.

High quality and rugged construc- tion are characteristic of both cranes and special attachments.

Hagglunds deck cranes are avail- able with capacities from 5 t to 240 t SWL, in single, twin or Team
