The monorail crane previouslysuspended from the cap timbers of the trestle bentsalong the river and used for reclaiming the coal fromthat storage pile, was later transferred to the steelpick-up bridge and suspended on the center line of itslower chord. A power rail supplies energy to its motor. When the order for the traveling transfer bridgehad been placed, the first work done in connection withthe new storage area was to construct the footings andtrack for the traveling bridge. These footings weremade of concrete set in the ground an average of 5 where they rested on solid ground. These werethen spanned by 8-in. x 12-in. yellow pine stringers, towhich the 100-lb. T-rails were fastened with spikes. At the same time work progressed on aconcrete unloading pit 40 ft. long by 23 ft. wide andof sufficient capacity to contain three carloads of pit was located at one side of the storage area. FIG. 4—SPECIAL AXLE BEARING BRASSES FOR TRAVEL-ING TRANSFER BRIDGE where the coal could be removed from it by the pick-upbridge, and so situated longitudinally that the lengthof track either side of the pit provided sufficient spacefor two cars. Three cars at a time could thus be setin the yard clear of the main industrial track of theManufacturers Railroad, and with the first car standingover the pit. The electric car which is used in haulingthe ash cars from the plant to the dump is also used inshifting the standard coal cars. One of the problems which came up in connection withthe transfer from the old to the new layout was thelowering of the old trestle 28 ft. without interruptingthe operation of the coal cars at the higher level. Thiswas done by cutting off the posts in the bents, and fram-ing in new caps and stringers in the section of thetrestle between the unloading mast and the conveyorhopper. New rails were laid and when ready, the carsand the
