"Mr. Klimax" was really  a Marion M7800 dragline  built in 1957-1958,  at Estevan Saskatchewan Canada for use at Utility Coal Mine, then in 1970, moved to the Boundary Dam Mine. It had a 220 foot boom originally. but after rebuilding in 1970, the boom was extended by 20 feet. This added 25 tons extra to the original weight. It's name comes from another mine  in the Estevan area. The Klimax Mine. In it's day it was a very impressive machine, and the talk of the city. Everyone knew about "Mr. Klimax"! I remember as a kid they built a special rail spur through the valley and up the hill from the north, to Utility Coals area, near Boundary Dam. As far as I can remember this is where  "Mr Klimax" was assembled. All the parts to build the machine, were brought in by railroad. After assembly the rail line was removed. Original specs of the Marion 7800 Weight- 3,205,000 lbs Height to top of cab= 34' 6" Length of boom= 220' 0" Capacity of bucket= 35 Cubic yards Dumping radius= 211' 0" Electrically Operated- 2,500 total Horse Power Marjorie Turton tells me the original boom was shortened by 20 feet afterwards due to too much strain on the dragline for the overburden they were digging in. I noticed a distinctive feature of this dragline is the round, tear drop shaped structure on the right, top, front of the House structure. Marion name is painted on this to identify the maker. Strange thing is, this cover, Cowl, or metal shape, doesn't appear on the first "Mr. Klimax"? But later on you will see a picture with this structure, with Marion painted on it, and "Mr. Klimax" painted on the side. After the rebuild, it was supposedly,  no longer "Mr. Klimax". So I am at a loss when this was added and why. If you know, please let me know. Ask and someone will tell you Mr Aaron Honyara sent me this email from PA, USA message =  Great pics, on the first page of the Mr. Klimax you asked what the tear drop structure was for. If you carefully look where the drag cable enters the house  it goes around the first wheel and goes up a tube on the front and then inside the tear drop,  it goes on a wheel that's inside that structure then down to the drag drum. Hopefully this info helps you Now I know, and you too! "Mr. Klimax" was originally painted on the sides of the House, behind the A frames. It was at the time, in 1957, the Largest Walking Dragline in Canada, and for many years after. Doing research on this machine, I found out other draglines had the walking feature before this model. For years I thought it was the first, but that isn't true. It originally was painted the Utility Coals colors, Dark yellow, (burnt Orange?) with reddish brown trim I only found one color picture of this machine. Hope you enjoy the "Mr. Klimax" tour.
