Largest Ship Unloaders Being Built By Dravo For Bethlehem Ore Pier The nation's three largest ship unloaders will serve Bethlehem Steel Corporation's new $50-mil-lion ore unloading pier and stock-piling complex now under con-struction at Sparrows Point. Md., site of the largest steel plant in the U.S. The new unloaders, together with two bucket-wheel stacker-re-claimers, will greatly speed up the unloading procedure as well as keep pace with the growing size of giant ore carriers now in serv-ice and on the drawing boards. Dravo Corporation, Pittsburgh, is designing and fabricating the three unloaders and two stacker-re-claimers. Bethlehem has urged the deep-ening of the Baltimore harbor channel from the present 42 feet to 50 feet to permit the handling of ships comparable to those in service or on order for European and Japanese steel producers. Each unloader will feature a cantilevered boom that provides for a bucket reach of 100 feet from the pier fenderline?believed to be the longest of any unloader now op-erating in the U.S. This compares with an average reach of from 70 to 90 feet for existing U.S. unload-ers. Operating on cycles of 44 sec-onds for each pass, the three un-loaders will have a combined free SHIP REPAIR Dependable 24-Hour Service REPAIRS & CONVERSIONS TO ALL TYPES OF FLOATING EQUIPMENT 3 BERTHS at YARD Topside Repairs At Unloading Docks PORTABLE EQUIPMENT FOR COMPLETE REPAIRS BENDER Ship Repair, Inc. 265 S.

Exceptional-ly-engineered Keariott Heated Windows are utilized year 'round under a wide range of climate, weather and tempera-ture conditions. The windows are manufactured as complete assemblies, ready ior installa-tion in a ship's structure. Electrical energy is supplied to the conducting film by means oi bus bars located at opposite edges. Current input provides sufficient thermal energy to maintain an ice-free, frost-free, fog-free window, the heating oi which is controlled by a specially designed control unit containing two hermetically sealed preset cycling thermo-stats. Write for Catalog on Kearfott Windows and Wipers digging capacity of about 6,450 net tons an hour. Each bucket-wheel stacker-re-claimer, operating in the ore stor-age yard, will be designed to stock iron ore or pellets equalling the output rate of the three unloaders. The reclaiming rate from the stor-age pile will range up to 4,000 net tons an hour per machine. Each machine has a capacity approxi-mately 300 percent greater than the conventional ore bridge used in stocking and reclaiming operations. The three unloaders will travel on rails along the new 1,020-foot-long pier complex. To make it pos-sible for the machines to unload vessels on either side of the pier, the unloaders are designed so that the upper tower and boom can be rotated through a full circle. The unloading buckets will be suspended on and operated by wire rope. The operator's cab will be suspended from the boom during unloading operations and can be retracted into the tower structure. Hoist speed of the bucket will be 340 feet per minute, and the trolley will move back and forth at a speed of 750 feet per minute. R.
