. Material handling cyclopedia; a reference book covering definitions, descriptions, illustrations and methods of use of material handling machines employed in industry . , The length inside of the body of coal mine cars isordinarily from 8 ft. to 10 ft. and the wheel base from 28in. to 32 in. The length and capacity could be increasedby using a longer wheel base but the objection to sodoing is the greater difficulty in replacing derailed carsand the larger radius of curves necessary to ensure easyrunning. For low seams the height of the car is restricted tonarrow limits. Some cars are used whose height is lessthan 20 in. For thick seams • the height of the car is de-pendent upon what is the most economical height for handshoveling, if this method of loading is employed. As thephysical effort is dependent upon the height to which thecoal is to be lifted, it has been found that a man canshovel considerably more coal per day into low than intohigh cars. For this reason some large operators will hotuse cars whose heights exceed 32 in. Where machineloading is employed the height may be as much as 48 in.,or even 60 in. 612 INDUSTRIAL RAIL TRANSPORTATION.
