The road distance for truck or rail gjisge was much longer. ;jjf Careful studies indicated belt haulage by the 'ecf route would be most economical. Jeffrey en* e<ii* were given the job of designing and Installing St is believed to be.the longest belt conveying Kta fn the country using a 24" belt. Coal for the Poston power plant now feeds m eiflired and weighed quantities from the mine sup* pf^by means of a Jeffrey Waytrol onto a 3,448 foot (octiae belt with a lift of 172 feet. This takes it to transfer point where it starts a 3,291 foot decline to the plant. Both belts, 24" wide, carry 300 tons of coal ah hour at 370 feet per minute over Jeffrey Re liance idlers. At the discharge end a 36" Jeffrey Boom Stor age Conveyor feeds the hopper. Two Jeffrey-Traylor Vibrating Feeders at the bottom of the hopper feed 300 tons an hour onto a 36" belt conveyor that rises to the crusher house. A 36" belt under the crusher carries the same 300 tons an hour into the plant to keep the big Poston bunkers continuously fed.
