Talk:Wheel tractor-scraper

I wish to Query fact that; LeTourneau invented the scraper. As the book on LeTourneau Earthmovers by EC Orlemann, (p11) indicates that LeTourneau adapted a standard towed scraper to form the first ONE-Man operated Pulled scraper by fitting motors to actuate the controls in place of the need for a driver to ride the scraper as was the normal operating method. Pulled scrappers had been around for years before then as a horse drawn implement. ref: 500years of Earth moving (P80) by Heinz-Herbert-Cohrs. He built the worlds 1st Electric self propelled scraper in 1923, from scrap and surplus parts. Ref: LeTourneau Earthmovers by EC Orlemann, (p13) BulldozerD11 (talk) 14:19, 14 April 2008 (UTC)

Corrrection of incorrect statement on elevating scrapers

While a founder and owner of Square Deal Machinery, Florida largest heavy equipment dealer for over 20 years, I purchased a new demonstrator Terex GM Model TS24 twin engine all wheel drive scraper based on incorrect factory assurances it would self load in Florida sand. Driving through Hastings Florida's potato growing area I saw a small John Deere farm tractor with a three point hitch leveling land pulling a cutting blade, elevating the cut material with revolving flights into a spreading container, and leveling the spread material with a second blade. I then took one of Florida's largest earthmoving contractors, Charles Smith of Smith Engineering and Construction Co, to confirm my opinion that this system could self load scrapers better than tractor push loading, and built a similar hydraulically actuated rotating drag flights identical to today's elevating scraper on the TS24, successfully proving its self loading ability to GM, who refused to follow up because "the market was too "limited" -and I was too naive at that time to patent . While the machine was in my shop I received a visit from a Mr. Hancock who was visiting Adams Equipment Co. down the street to promote his pull type scrapers for Letourneau-Westinghouse and had heard of my scrapers success. He took pictures and closely examined my elevating scraper and returned to Texas where he duplicated it for Letourneau-Westinghouse, who proved GM wrong on its "limited market." I can verify through still living witnesses the accuracy of these facts, GM will have a record also, and I respectfully request you correct the misinformation in your elevating page that Hancock developed the elevating scraper. For credibility I also enclose a short bibliography

Suggested new heading for this material - Earthmoving Scrapers

I would like to do some editing work on this subject matter, as scrapers are of historical interest, already covered in some other WP sections, but are also an important part of the modern construction industry, in Civil, Mining, and Agriculture construction. Much could be written under the categories Elevating Scraper, Open Bowl Scraper, and Laser bucket (tractor or dozer drawn), and parts of this material currently under the somewhat clumsy heading "Wheel tractor-scraper", could be included in the proper subsection. This would make for better reading, and be a better general source of information on all scrapers.

I propose renaming the heading "Earthmoving Scrapers", and including at least sections on History, referencing existing WP articles, and the aforementioned sub headings. Other sub headings could cover related machine types/variants, and be added as contributors have time and interest.

Please add comments here to guide this process, especially original article contributors. (My interest comes from 30 years owning, operating, and repairing Wabco and LeTourneau scrapers, and from general reading on the history of development and manufacturing of these machines, up to the present day) Weaknees (talk) 11:15, 12 December 2015 (UTC)

Better picture?

None of the pictures are really great for showing what the scraper does. We'd need a picture from an angle showing into the machine to really elucidate how it works. (Not sure it would be safe to get in position to take the picture if it it were operating at the time.) Any ideas for a better picture for this article? RJFJR (talk) 15:48, 8 April 2016 (UTC)
