Marion
 
Bucyrus acquired the Marion Power Shovel Company in 1997. This takeover of the second largest dragline manufacturer in the business (Bucyrus being the largest) effectively ended an intensive competitive rivalry between these two companies, a rivalry lasting some 113 years. Marion had been established in 1880 as the Marion Steam Shovel Dredge Company and grew into one of the foremost manufacturers of excavating machines. Marion built its first walking dragline in 1939 and became a key player in providing giant stripping shovels to the coal industry, being the first to put a long-boom revolving stripping shovel to work in North America in 1911. Marion’s succession of giant shovels, many breaking world size records, culminated in the world’s largest in 1965. This behemoth, the Marion 6360 at the Captain Mine, Illinois, wielded a 180 cubic yard (138 cubic meter) dipper. With an estimated weight of 15,000 tons (13,600 tonnes), this machine still holds the record as the heaviest mobile land machine ever built. Marion entered the walking dragline business in 1939 and just three years later produced the largest dragline built up to that time. In April 1946, the company changed its name to the Marion Power Shovel Company to more closely reflect its products.

Marion made headlines when it built the famous Apollo moon rocket transporters for NASA in 1965. Based on stripping shovel undercarriage technology, the two diesel-electric transporters were designed to move fully assembled lunar spacecraft and rockets from the assembly building at Cape Canaveral to the launch pad, a distance of three miles. These huge vehicles weighing 3,000 tons (2,722 tonnes) without load are powered by six diesel generator sets generating 7,600 horsepower (5,667 kilowatts). Still in use today, the transporters have taken part in most of the major space programs including the Space Shuttle.

The Marion acquisition broadened Bucyrus’ product line, adding over 120 operating draglines to its fleet and enabling Bucyrus to gain a wealth of technical data relative to design concepts and historical performance of its former chief competitor. Updated versions of some former Marion machines are now marketed under the Bucyrus banner. The reinforcement of the shovel product line with the Marion 351M (now the 595B) coupled with the existing successful 495-series shovels, places Bucyrus in an ideal position to satisfy customer requirements.
