. Material handling cyclopedia; a reference book covering definitions, descriptions, illustrations and methods of use of material handling machines employed in industry . the wheels may be equipped with rollers in the wheels are usually from 12 in. to 16 in. in diameter. Cars of the trunnion type are usually made only in smallsizes, ranging from 12 cu. ft. to 40 cu. ft. capacity. By usingswivel trucks, a wheel-base of from SO in. to 60 in. is pos-sible ; this pennits the body being carried between the wheels,and gives a low center of gravity. Such cars are very con-venient for loading. In dumping, the edge of the car comesdown to the rail. This is desirable for unloading into a pitor from a trestle, but is not so convenient when the tracksare on a level floor. Small cars of the trunnion type arealso made with a short rigid wheel-base and body above thewheels; this gives a car of compact design which is preferredin places where the load is dumped onto shop floors. Cars of the cradle type are ordinarily built for capacitiesranging from 18 cu. ft. to 40 cu. ft. with 24 in. track gage;27 cu. ft. to 54 cu. ft. with 30 in. gage, and 27 cu. ft. to 81. Fig. 9—V-Body Dump Car, Rocket Type braced to secure end stiffness. The frame is of channel iron,rounded to do away with joints at the corners thus givinga compact, strong construction and avoiding interferencebetween cars when passing around sharp curves. Thejournals are placed outside of the wheels. The car il-lustrated is equipped with a simple form of lever brakeoperated from the side of the car. The rocker type car is similar to the cradle type, exceptthat the body is provided with a rocker having projectionsengaging with holes in the horizontal rocker support onwhich the body rolls. This car is made in the same sizes asthe cradle type. It is usually preferable for the largersizes. V-body dump cars of large capacity are also built. Theseare adapted for locomotive haulage and steam shovel load-ing. The substant
