Steel Rollers Are Used for Handling Rough Material irregular objects low side-guards are advisable. Grades offrom 4 per cent to 8 per cent are usual. With heavypackages of fairly regular – shape the guards should beomitted in order to facilitate the handling .on and o.ff.theconveyor. Since hard service is usually required of a foundry con-veyor, extra heavy bearings are recommended. When theconveyor is used out of doors or where much sand anddust is being thrown ofif by the packages, care must betaken to keep the bearings well oiled but not to allow oil to collect the dust. Because of the rough and irregularsurface of the packages to be handled a greater grade isrequired than for ordinarily smooth packages. Structural SteelPlates—Shapes The possibility of handling large fiat objects much widerthan the conveyor rollers considerably broadens the scopeof gravity conveying. Sheets of steel and similar ma-terials, such as bars, rails and other sections, travel

Handling Flat Stock on Double Rollers smoothly on either curved or straight sections from thecars to stock piles, or from storage to the punches, shears,or other machines. In moving these heavy pieces from oneoperation to another with the least manual labor or time,the gravity conveyor serves a most useful purpose. Itsportability makes it economical even in the most congestedplaces. For such heavy duty the rollers should be of steel, withextra heavy bearings and rollers, preferably 10 gage or 12gage seamless tubing. For the heavier pieces even S gagetubing is none too heavy. For this work roller bearingsare often better than ball bearings, particularly at the load-ing sections, because of their greater strength. Rollerlengths of 24 in. to 36 in. are usual for handling such plates,with centers spaced from 6 in. to 12 in., depending on thelength of pieces to be handled. While it may occasionallybe necessary to use side-guards, these are generally incon-venient. The grades required are s
