Marine Travelift Introduces

Another New Model In

Its Boat Hoist Line

Marine Travelift, Inc. of Stur- geon Bay, Wise., has announced another new model in a continu- ing program of development of its "Beam Forward" design concept for mobile boat hoists. Latest in the series is the 60BFM model with a lifting capacity of 60 tons.

Besides numerous maintenance and efficiency features, the new hoist also has a variety of operator conveniences to permit fast han- dling of a wide variety of commer- cial and recreational vessels.

The first 60BFM was delivered to a busy West Coast marine. Suc- ceeding models were installed in

Florida and in various East Coast operations.

KEVLAR aramid means lighter marine systems...less costly, easier to handle.

Now you can get the strength you need in large marine ropes for offshore oil rigs and other maritime applications-at only 1/5 the weight of steel in air and 1/20 the weight in water.

In pendant applications, for example, lightweight ropes of

DuPont KEVLAR aramid fiber permit use of smaller, lighter buoys (photo at right) and allow faster anchor deployment and retrieval. Significant systems cost reductions can be realized.

In riser tensioner applica- tions, ropes of KEVLAR last up to 4 times longer in actual field use, due to their superior cyclic fatigue properties. Ease of handling provides important savings in in- stallation time and labor.

Towing lines of KEVLAR can provide extra years of service, because of superior fatigue and corrosion resistance.

Ropes of KEVLAR are unaffected by saltwater, organic

The small, less expensive buoy handles a pendant line of

KEVLAR. A buoy 20 times larger in volume is needed to handle the same length of steel line. solvents, drilling fluids and lubricants.

Ropes of KEVLAR are available in wire rope and other constructions to meet your specific needs. For more infor- mation and a list of quality manufacturers, call the toll-free number below. Or write: Du Pont

Norwinch And MTT Unveil

New Shipboard Crane — Literature Available

Two companies based in Bergen,

Norway—Norwinch and MTT (Marine Transport Technology)

A/S—have developed an electro- hydraulic cargo crane, the proto- type of which has been demon- strated to a number of ship owners.

According to Reidar Rasmussen, sales manager for Norwinch, the new crane has created a great deal of interest abroad, and orders have already been received. Production under license has been established in Spain, where seven cranes are already under construction.

MTT is an engineering company that specializes in the construction of cranes for the merchant fleet and the offshore industry. Tor

Roksvaag, director of MTT, says that the company supplies ships' equipment worth approximately 20 million Norwegian kroner an- nually. He states that the new crane incorporates several advan- tages compared with cranes of similar type. The crane requires a minimum of deck space, which is especially important for contain- erships.

The Norwinch low-pressure hy- draulic components chosen for op- erating the new crane are well known for their reliability, and are especially suited for continu- ous running under severe condi- tions with a minimum of inspec- tion and maintenance. Last year

Norwinch had total sales of ap- proximately 200 million NOK.

The new crane will be marketed through the Norwinch Group's worldwide agent network.

Hydra-Dynamics Offers

Brochure On Its Air And

Hydraulic Cylinder Line

Hydra-Dynamics, Inc. of Wil- mett6, 111., has available a new catalog describing its line of heavy- duty, welded-design air and hy- draulic cylinders up to 60 inches in diameter and with operating pressures up to 5,000 psi.

Typical severe service applica- tions where this design has proven itself include offshore drilling rigs, sub-sea pipeline clamps, material handling, construction equipment, machine tools, and foundries.

The company considers service a critical part of its operations, and has established a 24-hour-a-day, seven days per week hotline—(312) 251-2400—for its customers. In addition to its standard catalog line, Hydra-Dynamics will custom design and manufacture cylinders to virtually any specification.
