A REVIEW

Marathon LeTourneau's Marine Pedestal Crane BWTifflHffir^ ' f1 '^i TliniMBnrinf

The boom in offshore drill rig ordering during the past year—a total of 156 were contracted for during 1980 worldwide — broke all previous records. At year-end, there were 195 rigs of all types on order. This, along with the hundreds of vessels needed to serve these new rigs, has sparked the market for all types of deck machinery, including cranes, winches, capstans, windlasses, and mooring systems.

We asked the major manufac- turers of deck machinery to tell us about their equipment and marketing plans; this review is based on their replies. For addi- tional information and free lit- erature on deck machinery,

BEEBE BROS.

Beebe Bros., Inc. of Seattle re- cently announced a major new improvement to the Beebe-65

Barge Wrinch, which is widely used throughout the industry, an electric brake that increases hold- ing capacity from 60,000 to 70,000 pounds. The barge connector with the new, higher holding capacity brake continues to feature quick- release dogs with holding capaci- ties up to 100,000 pounds. Accord- ing to Beebe, the design of the electric brake not only increases braking torque and holding ca- pacity, but reduces brake adjust- ment requirements and extends brake life.

Built for use with U/i-inch- diameter and smaller lines, the unit is said to be fast and easy to operate electrically by remote control from the pilothouse, deck, or both. The Beebe-65 winch is also available with air or hydrau- lic motors.
