Text Appearing Before Image:
ck trucks, is subject to severeoscillatory stresses when the loadedcrane is travelling. The plating is,therefore, made very deep, and sup- ported with massive angle brackets andbraced in all directions with broad chan-nels. The travelling of these huge masses,weighing from 200 to 300 tons, is ac-complished in one of two ways, eitherthrough pitch chains or bevel wheels.This operation, like those of racking,lifting, and slewing, is performed froma single set of double-cylinder engines.The pitch chains, being long, sag andoperate the travelling wheels in a ratherjerky manner, causing reversal to be-come a nuisance, and they also stretchwith service. The bevel gears, on theother hand, are liable to fracture, sothat it is necessary to carry their shaftbearings in stiff brackets well tied to-gether, and to see that the plating towhich the brackets are bolted is wellstiffened with diaphragms or stiffeningribs. Both systems of driving areadopted, as they are in Goliaths. 396 CASSIERS MAGAZINE

It is much quicker to work inthis way than to slew the crane each high quality. The joints are plated inthe girder work, and as the mechanismhas to be shipped in sections, this meansthat these sections have to be bolted to-gether temporarily during erection andfor testing. Punched holes are neverallowed here, but the holes are either
