FIG. 15.—A 5-TON ELECTRIC LOCOMOTIVE REVOLVING CRANE, 16 FEET RADIUS, BUILT BY THEBEURATHER MASCHINENFABRIK, BEURATH, GERMANY to cause depressions in it but for thepractice of mounting the wheel bearingsagainst springs. When a Titan hasto take quick curves, bogies are used. Steady rotation of the jib is ensuredby the large diameter of the wheel race,—30 to 35 feet,—and the distributionof the load over two to three dozenturned rollers running between turnedroller paths. The very large diameter?of the roller race is a noticeable featureof this type. This, together with thefact that the boiler, engine and gearsare placed behind or within the circle ofthe race, and that supplementary ballastis also placed behind, ensures the stabil-ity of the crane under maximum loadsat maximum radii. The tall framing, made high to clearthe block trucks, is subject to severeoscillatory stresses when the loadedcrane is travelling. The plating is,therefore, made very deep, and sup- ported with massi
