Tools for Steel Car Work The following machie tool equipment is recommendedfor a car repair shop which is to handle the variety of typesof steel cars used on the majority of railways: One single end punch (24 in. throat), motor driven. One double punch and shear (30 in. throat), motor driven. One double horizontal punch and bending machine, motor driven. One 8-ft. gate shear (cap. J4 n- Pate), motor driven. One 6-in. by 6-in. by 1-in. angle shears, motor driven. One alligator bar shear, motor driven. One plate straightening press, pneumatic. One 9-ft. by 14-ft. plate heating furnace, oil and gas burning-. *:;::::: Futjre Exte ns,. Plan for a Steel Freight Car Repair Shop with a Transverse Layout, Two 60-ft. Aisles substitute for this two bays of 44 ft. each. The use ofcenter columns should enable the designer to lighten thesteel work in the roof trusses and provide good support forjib cranes. It will be less expensive to install two and equip each one with a 15-ton hoist and an aux-iliary rapid hoist of smaller capacity, than it would be toput in one crane of 84 ft. span, and they will serve the shopmore efficiently. It is recommended that the lengthwisetravel of cranes be limited to 300 ft., preferably about 250ft., so that a shop unit from 500 to 600 ft. long shouldhave at least two cranes, or sets of cranes. Jib cranes ofthe portable type, or attached to steel columns are an ex-cellent means of handling work at car spots and at certainof the machine tools. They release the overhead cranes forgeneral transportation and material handling through thewhole shop. The j
