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.

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 CRANES SPECIAL FEATURE DELIVERIES TO U.S. BUILT-SHIPS 1973 U.S. Coast Guard (Single Ice Class) 1974 States Line/Lykes (Twin) 1975 Moore McCormack(Twin/ Single) 1979 American Atlantic (Team) 1981 C&H Sugar (Grab) Advanced cargo-handling gear that advances the efficiency of U.S.-built Ships is HAGGLUNDS contribution to American Shipping.
