Deck Machinery — A Review Clyde Iron (continued from page 10) installations in recent years is aboard the giant semisubmersible, 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, rugged, and easy to maintain, that crane was customized and tailored to meet the huge barge's unique re- quirements. 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 pull,/ 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.
