Popular Post 85snowdog Posted April 11, 2020 Popular Post Share Posted April 11, 2020 I came across this interesting video I wanted to share. Its a 1940's dealer movie, that shows modern earth moving methods. Its a great video. I didn't actually know that Allis Chalmers used 2 stroke engines. I am always learning something new. I will add a pic of a very nice HD 6 I was fortunate to see. https://www.youtube.com/watch?v=7SVq-rzh9pU 3 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/61998-allis-chalmers-modern-earth-moving-video/ Share on other sites More sharing options...
Rob Posted April 11, 2020 Share Posted April 11, 2020 Every HD-5, and HD-6 I've ever seen had Detroit Diesel two stroke engines installed. Don't know if that was only option, or spec'd that way. Seen one Allis crawler with a Buda diesel built before Allis purchased Buda. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Bullheaded Posted April 12, 2020 Share Posted April 12, 2020 I know they made some big 4WD sugar cane tractors and at the time they were having a lot of issues with their own engines and almost all of them were repowered with Detroit's. There are a lot of really cool old Allis Chalmers dealer videos on You Tube. For both their farm tractors and the motor graders. Allis Chalmers was another company like White Motor Corp. It is amazing how big and much stuff they were into. Everything from crushers to power generation. There is still Allis Chalmers crushers working in the slag processing area of our steel mill. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/61998-allis-chalmers-modern-earth-moving-video/#findComment-448530 Share on other sites More sharing options...
85snowdog Posted April 13, 2020 Author Share Posted April 13, 2020 I love how this stuff can be used for 50 years or more ,and still do the job it was intended for. Definitely built for longevity , and not be replaced every 5 years . 1 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/61998-allis-chalmers-modern-earth-moving-video/#findComment-448612 Share on other sites More sharing options...
Red Horse Posted April 13, 2020 Share Posted April 13, 2020 Anyone have a clue how those cable dozers were set up to control a cable scraper? I would think they had to have three separate drums- one to control height/cut depth of the bowl, one to raise/lower the apron, and one to control the ejector plate. Or was the apron/ejector on same drum? That is, raise apron minimal height to load, keep raising and at a certain point the ejector starts moving forward to dump?????

Swishy Posted April 14, 2020 Share Posted April 14, 2020 AFAIK on the rear of the dozer they had a Duble Drum Power Control Unit (PCU) On sum C@ dozers they had also a front run wire rope control to raise and lower the dozer blade U could unhook the blade or chain the blade up and run the wire rope south to also control the drawn scraper WotSezU? cya 2 Quote Link to comment https://www.bigmacktrucks.com/topic/61998-allis-chalmers-modern-earth-moving-video/#findComment-448714 Share on other sites More sharing options...

Pull on cable and apron raises to start loading. At a certain point once apron reaches a given height the ejector starts moving forward. At max ht of apron the ejector plate would be all the way up/forward.
