Popular Post Joseph Cummings Posted Monday at 08:59 PM Popular Post Share Posted Monday at 08:59 PM Famous truck in the Kentucky Coalfields. Crazy Big Cat power. I seem to remember it being a 3500 series industrial. The last I heard it was in pieces in MMI's yard 6 Quote Link to comment https://www.bigmacktrucks.com/topic/74797-mining-machinery-inc-rd800-cat-powered/ Share on other sites More sharing options...

It's adjustable, if it's like the ones I used it's hydraulic. It probably uses the Fifth wheel that takes the large pin. Or like some I've pulled the pins were swappable. I think that orange DM800 that has the Bethlehem Steel on the door has the big fifth wheel on it, or at least it did when it worked at the mill. McHugh sometimes used one of these Cline Prime Movers that they built from off road dumps to pull trailers like that with the tall gooseneck 3 Quote Link to comment https://www.bigmacktrucks.com/topic/74797-mining-machinery-inc-rd800-cat-powered/#findComment-562638 Share on other sites More sharing options...
Popular Post Joseph Cummings Posted Monday at 11:53 PM Author Popular Post Share Posted Monday at 11:53 PM I just checked, it had a Cat 3412 engine in it. The story is that they wanted Carter Machinery to install it, and Carter refused, so they did it in their own shop. Carter Machinery is a super huge Cat dealer in that area 3 Quote Link to comment https://www.bigmacktrucks.com/topic/74797-mining-machinery-inc-rd800-cat-powered/#findComment-562640 Share on other sites More sharing options...

Thanks for posting. I took their 4 axle autocar and a 4 axle Rogers to Parkersburg WV to pick up a Tadano Mantis back back in about 1986. Not too long after leaving Parkersburg I was using the jakes and the elbow blew out right below the muffler. Talk about screaming. By the time I got home my ears rang for a week 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74797-mining-machinery-inc-rd800-cat-powered/#findComment-562655 Share on other sites More sharing options...
The Heinz Posted 19 hours ago Share Posted 19 hours ago The 3412 is a beast of an engine for that Bulldog! Shame it's in pieces, I'd love some videos of that beast running. It's like the American equivalent to the last Pacific truck ever made, a P12W3 with a 3412 Cat, built in the parts warehouse. Some interesting videos of the truck being tested after completion on Youtube. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74797-mining-machinery-inc-rd800-cat-powered/#findComment-562663 Share on other sites More sharing options...

Every 3412 I've ever seen has a huge radiator 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74797-mining-machinery-inc-rd800-cat-powered/#findComment-562674 Share on other sites More sharing options...
Mark T Posted 10 hours ago Share Posted 10 hours ago I almost looks like it has 4 electric fans in front of the radiator in the picture. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74797-mining-machinery-inc-rd800-cat-powered/#findComment-562686 Share on other sites More sharing options...

Yeah I blew the picture up and it does look like fans. I'd love to see under the hood Quote Link to comment https://www.bigmacktrucks.com/topic/74797-mining-machinery-inc-rd800-cat-powered/#findComment-562691 Share on other sites More sharing options...
