398 is determined by the overhang of the *legs. This has the effect of doing away with shifting ballast. The girders ex- tend across the rear pontoon and the head guys are attached to their, extremi- ties. Three sets of falls are provided, of 100-ton, 20-ton and 5-ton capacity, respectively. The Vulcan Co. has already at its yard at Stettin two floating shears of 100-ton and 50-ton capacity, and that they have been satisfactory is evident 'Tae Marine REVIEW for which the new yard is specially fitted, this shifting involves much time and labor. In the background will be seen a type of crane which has come into considerable favor in recent years for fitting out docks, namely, the tower crane, which not only has a movement parallel with the face of the wharf but has a range of the entire circle covered by the cantilever arm. Other examples of large floating One Hunoprep-Ton FLoatTiInGc SHEAR a Bhp by the addition. of this third unit at the new yard. In the fitting out of large ships under a stationary leg the ship has to be con- tinually shifted in order to bring the point of deposit 'fairly under the head of the shears, and with the large ships Lec AT VULCAN Co.'s YARD, HamBurc. cranes of still greater capacity are to be found atiHarland &) Wolff's ship- yard, Belfast) Ireland, and at Krupp's, Kiel, Germany. Both of these are of the same type and capacity, namely, 150 tons. In size, however, these cranes completely dwarf those previously de- October, 1910 scribed. The cranes are of the lift jib type, the jib being pivoted at the top of a revolving tower. The peak of the jib in its highest position is 245 feet above the deck of the pontoon. The working radius with full load is 98 feet 6 inches; with 110 tons, 131 feet; and with 35 tons, 148 feet. A test load of 200 tons was applied at the normal full load radius, 98 feet 6 inches. The least radius of the peak of the jib, from which the 150-ton fall is hung, ig 32 feet 10 inches; There' are, in addition, two auxiliary trolleys of 35 and 10 tons capacity respectively, which travel along the lower flange of the jib. Two motors with a total horsepower of 135 are provided for the 150-ton fall, one 90-horsepower motor for the 35-ton trolley and one of 55 horsepower for the 10-ton trolley. Two 17-horse- power motors operate the turning gear, effecting a complete turn in 6% minutes. The pontoon, which is self-propelling, has a length of 131 feet, a width of 85 feet 4 inches and a depth of 14 feet 9 inches. The crane tower is lo- cated on the center line of the pontoon. The greatest angle of heel of the pon- toon with maximum load at maximum radius is stated to be between 5 and © degrees: - New Steamer for Mer- chants' Transpor- tation Co. Manager F. H. Marvin, of the Mer- chants' Transportation Co., Tacoma, has placed a contract for the construc- tion of a single screw, passenger boat for the Tacoma-Olympia run with Martinolich Bros., Dockton, Wash.
