POPULAR ELECTRICITY MAGAZINE Electric Monorail Systems Unlike ordinary traveling cranes whichare limited to one: straight run a craneoperated upon a single or monorail trackcan go from building to building, aroundcurves and upon numerous branch tracks,inside or outside. The two lower illustrations show twosuch installations in operation—one hand-ling heavy metal in severe winter weath-er, the other operating an electric liftingmagnet. THE BAGS OF SUGAR ARE WHISKED ABOUT THROUGH MID-AIR from the weather but no other part ofthe equipment needs housing. In some instances the system is con-trolled from a distant point, as in thecase of the five electric double monorailhoists installed in the storehouse of theAmerican Sugar Refining Company,New Orleans, La. These machines for handling sugar areinteresting in that the trolleys are ar-ranged to run on T-rails, one of which isplaced on either flange of a built-up sec-tion having theg; form of an I-beam and theelectric hoistsare thus enabled

FLEXIBLE METHOD OF SWITCHING INMONORAIL SYSTEM Another advantage of this system isthe manner in, which the operator takesany desired track. He pulls the steeringlever which is located on the trolley nearthe controllers. This raises a horizontalroller to a position in which it engages acurved rib on the under side of theswitch tongue thus diverting the leadingtruck or set of wheels to the track de-sired. The operators cage contains a seat forhim and all appliances requisite for con-trol. If the trolley works out of doorsthe cage is usually housed for protection MONORAIL WITH LIFTING MAGNET ATTACHMENT to run at very high speeds with safety,and it is also maintained that for theoperation of nonorail systems, directcurrent is, preferable to alternating,owing to the superior speeds with lightloads obtainable with the former. These electric machines are of thesingle whip type and the hoisting motorsand the gearing are arranged to give avery high lifting speed, so that bags ofsugar can be un
