Deck Machinery Review (continued) • Elimination of any manual lash- ing. • Risk of accidents minimized. • No need for checking or retighten- ing of lashing during sea voyage. • Quicker placing or "spotting" of containers. • Handling operations can start without any preparation or unlash- ing work. • No waiting for intermediate lash- ing or work after completion. • Easy and safe access to reefer con- tainers. These considerable advantages have been achieved after much pre- liminary design work and prototype testing carried out by the efforts and expertise of ACL, TransConsul- tants, and MacGregor-Navire. The most obvious vessel that would gain maximum advantage from weatherdeck cell guides is the fully cellular containership. Other applications envisaged by MacGre- gor-Navire include the feeder ship, the bulk/container carrier, the open bulk carrier, and the whole spec- trum of CONRO, RO/RO, and RO/ LO designs. MANITEX Circle 36 on Reader Service Card Manitex Inc., a subsidiary of The Manitowoc Company, Inc., designs, manufactures, and markets pedes- tal-mounted box-boom and lattice- boom cranes at a modern, two-plant facility near McAllen, Texas. Ideally suited for dockside, ma- rine, land-based, or pedestal- mounted applications, Manitex Sea- Cranes are constructed of marine- quality components, with complete material traceability available upon request. In addition, each crane fea- tures a versatile modular design to permit fast servicing and easy changeability of components from model to model. The present family of Manitex SeaCranes includes four box-boom models: the 15-ton-capacity MB- 300; the 25-ton-capacity MB-600; the 40-ton-capacity MB-1200; and the 60-ton-capacity MB-2400. Manitex complements its box- boom cranes by offering six lattice- boom models, all available with full weather enclosures to permit opera- tion in harsh environments. Current lattice-boom models include: the 25- ton-capacity ML-600; 45-ton-capac- ity ML-1200; 55-ton-capacity ML- 2400; 75-ton-capacity ML-4800; and the 150-ton-capacity ML-9600. In addition, Manitex recently devel- oped its 200-ton-capacity ML- 14400, which is scheduled for de- livery to a major offshore drilling company in the near future. SeaCranes exceed the stringent operating codes established by the API, Lloyd's, DnV, NMD, and ABS. Other advantages and features in- clude all-modular designs, full 360- degree swing capability, auxiliary winch systems, single- and double- taper box booms, on-board and re- mote control systems, on-board and remote power units, anti-two-clock systems, and variable-height gantry arrangements. In addition, Mani- tex's worldwide distributor network provides complete parts and service availability 24 hours a day, seven days a week. MARATHON Circle 37 on Reader Service Card Marathon LeTourneau Compa- ny's line of port handling equipment is in operation around the world. The line includes the rubber-tired Model 2582CH, a top-pick sideport- er that lifts and carries 20- and 40- foot containers. The Model 2682SS (solid-state) sideporter handles both containers and trailers, and the SST-100 solid-state, single-beam straddle hoist handles both 20- and 40-foot containers. This straddle hoist can span up to six rows of containers stacked three high, with room to pass another con- tainer over the top. All Marathon LeTourneau port equipment is pow- ered by the company's dependable diesel-electric drive system. MARCO Circle 38 on Reader Service Card In addition to improvements made to existing products, Marco of Seattle introduced three new pieces of fishing deck machinery recently. First was a new aluminum longline drum, used in a variety of longline fisheries on both coasts of the U.S. and Canada, as well as in other areas of the world. The hydraulically pow- ered drum features gear drive that makes it powerful enough that no secondary hauler is required. The new unit also features a diamond- screw levelwind and a unique de- clutching motor and adjustable drag brake to control freewheeling speed. Marco's San Diego-based subsid- iary, Campbell Industries, recently introduced a long-needed product for the world's high-seas tuna purse seine fisheries. Its new purse block for large superseiners is larger and yet 50 percent lighter, as 210 pounds (95 kg), than any other block of its capacity (20T/18mt). This new, stronger block features a spring-loaded grease reservoir to automatically maintain lubrication under load, eliminating the problem of bearing failure due to inadequate lubrication. The design also handles 1-inch (25-mm) connecting links through its throat, which are neces- sary to handle the heavier loads on 7 /8-inch (22 mm) purse lines with 1- inch center piece. The most recent introduction by Marco was its unique line of Foam- Flo fish pumping systems. Designed to meet the particular needs of the salmon and herring fisheries, the FoamFlo was developed with its chief goal being fish quality. The challenge has been to develop a pump that could handle great quan- tities of product, and yet treat both small and large species without damage. With its unique combina- tion of injected water and air creat- ing flow, FoamFlo answers this im- portant challenge. MARKEY Circle 39 on Reader Service Card Markey Machinery Company's marine equipment production for 1985 reflected the generally limited activity of the entire industry. De- velopment work on larger anchor- handling and towing winches antici- pates the mooring in deeper waters that is coming. Large catcher/processor fishing vessels are requiring heavier winch equipment than the standard U.S. and imported units. And oceanogra- phers are seeking larger and more sophisticated winches with micro- processor-based instrumentation to increase data-gathering productivi- ty and payload protection. Although further adjustments ap- pear likely, these areas as well as spot requirements for robust deck machinery with low life-cycle costs are helping to bridge the gap. McELROY MACHINE Circle 40 on Reader Service Card McElroy Machine & Manufactur-ing Company of Gulfport, Miss., already actively manufacturing ma- rine deck equipment for the com- mercial fishing and offshore support industries, is now venturing into government equipment manufac- turing, as well as specialized com- mercial requirements. Presently, several contracts for the Depart- ment of Defense are being com- pleted, which are for diesel-driven, double-drum winches of several sizes. Contracts with the Army Corps of Engineers and the Coast Guard have been completed recent- ly, as well as an oceanographic winch for Johns Hopkins Universi- ty. The commercial fishing industry has seen McElroy supplying equip- ment for large catcher/processors, and an upswing in the standard Gulf of Mexico type trawlers. Also, a brisk overseas business for commer- cial fishing equipment has devel- oped. The trend in commercial work- boats has shifted to specialized ves- sels requiring purpose-designed equipment. These vessels include dredges, diving support craft, line- handling tugs, landing craft, fire- boats, as well as cruise ships and fer- ries. Each of these types has its own specific requirements, and McElroy has met each of the requirements in stride. Examples of this specialty equipment include a fiber optic ca- ble-laying reel for AT&T and a refueling-at-sea hose reel for the Ar- gentine Navy. This diversity has allowed McEl- roy to continue to grow and remain successful in these changing times. MORGAN CRANE Circle 41 on Reader Service Card Long established as a worldwide leader in the manufacture of articu- lating hydraulic cranes, HIAB- FOCO of Sweden now offers a full line of its Sea Cranes with American Bureau of Shipping certification. Available through HIAB Master Distributor Morgan Crane Compa- ny of Santa Ana, Calif., these cranes come equipped with any number of job-specified options.
