MARION 6360 270 TONS IN EACH PASS First in Excavator Engineering This overall view of the Marion 6360 at work doesn't tell the story of its size and rugged strength. The house roof, for instance, looms nine stories above the ground. The world's largest mobile land machine, a Marion 6360, is moving overburden 270 tons at a pass in round-the-clock operations for the Southwestern Illinois Coal Corporation. Two coal seams are being uncovered simultaneously at the Captain mine near Percy in Southern Illinois, as this tower of strength moves land that will be reclaimed later to provide cropland, new parks, lakes and game preserves. The eight-crawler Marion giant has a dipper capacity of Machinery deck erection was near completion on the 180 cubic yards, and a 215-foot boom that extends Marion 6360 when this photo was taken, showing one of the two big hoist drums towering over a Marion engineer 21 stories skyward. and erection chief. Operator and a mine official are dwarfed by the size of the machine. From his cab five stories above grade, the operator has almost instant response from fingertip and pedal controls. The shovel can propel itself at 1/4 mph on four pairs of big crawlers. Each crawler is 45 feet long, 16 feet high. Each crawler shoe measures 10 feet across and tips the scales at 3½ tons. This interior view shows the two hoist drums that are driven by eight 1000 hp electric motors, largest ever used in an excavator. The four 3½-inch wire ropes hoist the dipper through a two part hitch. One of eight 625 hp swing motors is in background. Four motor generator sets like this convert 14,000 volt A.C. Operator can telephone nine other stations on the power to direct current for the 20 main drive motors capable of machine, talk to the ground by loudspeaker, or to other 30,000 horsepower output.

A view from high up on the gantry, looking down through the There's more than a mile of wire rope in the Marion 6360. The 215-foot boom, shows a 65-cubic yard Marion 5761 stripper hefty dipper measures 24 feet from teeth to door, is 18 feet and a 15-yard Marion coal loader. wide, 24 feet high, and will dig 270 tons of earth and rock. Engineers inspect one of the eight enormous crawler truck assemblies during erection of the machine. Each has 42, 3½ ton, track shoes. The Marion 6360 exerts a bearing pressure of 61½ lbs. per square inch upon the ground.

The Marion 6360 is the latest in a series of "World's Largest" Marion excavators—shovels and draglines—at work in open pit mines around the world. It required 10 months for field erection at the Captain mine, where the machine works aro d the clock, seven days a week, helping deliver approximately 150 railroad carloads of coal a day. Meeting this challenge for the design, manufacture, shipping and erection of a machine twice as big as any Marion previously built, demonstrates the unmatched engineering skill and experience that has MARION POWER SHOVEL COMPANY, INC., Marion, Ohio A Subsidiary of Pittsburgh Coke & Chemical Co.
