Square-Body Rotary Dump Cars These cars, often called simply rotary dump cars, arequite similar to scoop-body dump cars, the principal dif-ference being that they have a body of a somewhat dif-ferent form. In the lighter types the body is sometimes made of steel,but is usually constructed of oak and is frequently linedwith sheet steel, which should be done if the cars areto be used to handle rock or shale. One end is generallyleft open, as shown in the illustration, for convenience inloading and in dumping, but a sloping end is sometimesused. On account of their low height which permits ofeasy hand-loading, their lightness and their ability to re-ceive and discharge the load in any direction, this formof car is used for many classes of construction work. They. Fig. 19—Light Square Body Rotary Dump Car from the screens to the waste pile, as well as for otherpurposes. The particular design shown is generally used wherethe cars are pushed by hand. Brakes are sometimes usedand are generally operated by a foot-power lever. Carsare usually made for 24 in., 30 in. and 36 in. track gage, butmay be made for any other gage. Usual capacities arethree-quarter, one, one-and-a-half and two cubic yards. Another design of a rotary dump car, of a heavier type,is largely used in certain classes of construction work,being particularly useful at the end of trains where it isdesired to dump over the end of an embankment or througha trestle. The car is substantially built for heavy may be dumped on either side, or at one end. To permitof end dumping the draft timbers are shortened a
