Public Open Days throughout the year. These were the models S-45, S-67, S-90, S-112 and S-152.
As well as these, a small number of the model S-45 were built in New Zealand by CWF Hamilton.In order to make their attachment range as broad as possible, Bucyrus-Erie also manufactured a cable operated ripper, the CR-2, and several sizes of sheepsfoot tamping compactor.Bulldozer Blades – Bucyrus-Erie made an extensive range of cable and hydraulically operated blades to fit the entire range of International-Harvester track type tractors.The tractor attachments business was really hot property in the period 1932 through 1960.These were the models S-45, S-67, S-90, S-112 and S-152.There were also three models of hydraulically operated two-axle scraper, the G-28, G-38 and G-58 which were very popular, especially with councils.They were instantly recognizable as Bucyrus-Erie products because of their mounting frame which featured a graceful, cast curve-shaped link between the hydraulic cylinders and the blade lift rods.They are also very difficult to top-load with a shovel or dragline.Not a great deal on offer here but there are some examples.All good things come to an end eventually and Bucyrus-Erie was no exception.The Bucyrus-Erie PCU could be fitted to all makes of track type tractor, not just International Harvesters.This gave them a very low centre of gravity so that they weren’t as prone to toppling over as some other brands were.These were sold under the trade names of Bullgrader and Bulldozer.The ejector was hinged just behind the cutting edge and was also lifted by cable from the rear, rolling the load out.They had quite a fast cable speed due to the fact that they would only accept a 2-part line and were not particularly popular, most operators preferring the hydraulic variety.These were simple designs, based on straight cable routing, and featured good line speeds.Surviving examples are very rare.International-Harvester absorbed the B-series scrapers into their own product range at the same time they acquired Bucyrus-Erie bulldozer blades.These are worth seeking out as they are good representations of the real thing.Bucyrus-Erie’s PCU range was sold to Superior Industries not too long after International-Harvester purchased Bucyrus-Erie in 1953.While Bucyrus-Erie products could be fitted to any brand of track type tractor, quite early on in the piece Bucyrus-Erie formed a very close association with McCormick-Deering which in turn was absorbed into International Harvester.Bucyrus-Erie’s entire blade range was absorbed by I-H in the late 1950s and also built under licence in Australia by Armstrong-Holland.UK-manufactured Bucyrus-Erie equipment was marketed as “Ruston-Bucyrus”, and featured engines and some components that were plentiful in the UK and Europe and didn’t have to be imported from the USA.The model B-170 was upgraded slightly with a capacity increase in 1955 becoming the B-170A, however none of the other ‘B’-scrapers were so altered.Bucyrus-Erie manufactured their own cable control units (PCU’s) in four different sized models – the P-14, a single drum unit primarily intended for dozer and ripper use, the C-22, a double-drum type designed for small track-type tractors (and not in production for very long) – the P-24, a double drum unit for tractors up to International TD-18 size, and the P-28, also a double drum unit designed for the largest track type tractors of the period.Before too long, Bucyrus-Erie shovels were becoming preferred equipment on jobsites due to their well thought out design and reliability.Bucyrus-Erie were also very conscious of the growing role of the crawler tractor in construction and in the late 1920s, began to design and market a range of complimentary attachments that could be fitted to them.These types of machines were popular in civil works for excavating car parks, garages and basements.These were of a far more conventional design than the previous ‘S’-models but still featured roll-out ejection, which required that the ejector cable be routed over the top of the load, exposing it to wear from dust.A great many of these machines found their way into New Zealand and Australia.The new Bucyrus-Erie units were the B-91, B-113, B170 and B-250 ranging in capacity from ten to twenty-seven cubic yards heaped.Bucyrus-Erie manufactured a tractor-shovel attachment that could be installed on International TD-9 and TD-14 tractors.The same company also builds a TD-18 tractor with a Bucyrus-Erie Bullgrader attachment and the same comments as above apply.There are also models of the International-Harvester TD-24 to 1:50 and 1:25 scale by Spec-Cast Models which feature Bucyrus-Erie PCU’s and blades.Both Hydraulic and Cable operated types were manufactured with the hydraulically operated Bullgraders being particularly popular on the small International TD-6, TD-9 and TD-14 tractors.They were of a design called a ‘throw-arm’ scraper and differed from conventional scrapers in that the bowl was raised and lowered from the rear and maintained a fairly flat profile throughout all phases of their operation.Both of these are to 1:50 scale.Although it was a bit clunky and over-engineered, it featured all hydraulic operation and had most of its mass at the back, ensuring a bit of operating counterweight.Bucyrus-Erie redesigned their entire towed scraper range in 1949, selling the existing S-series patents & jigs to Southwest Manufacturing of Alhambra, California, who continued to manufacture them under their own brand name well into the early 1970s.They differed from most of their competitors by having a very short cable lift tower and semi-cowled wheels.EMD Models build a very nice replica of an S-112 scraper with P-24 PCU but it is hard to find and expensive.Their big break came in 1927 when they merged with the cash-strapped Erie Steam Shovel Company, becoming Bucyrus-Erie.However, International were also very good buddies with Drott (inventors of the 4-in-one bucket), so when I-H acquired Bucyrus-Erie’s attachment division, the B-E loaders quickly faded into history.Initially, Bucyrus-Erie offered five different sized cable operated scraper models from five to seventeen cubic yards heaped capacity.This type of scraper has a lot of exposed cable which is susceptible to high wear under certain conditions.While their compactors were a little lightweight in construction and not particularly successful, the CR-2 ripper was the complete opposite, and Bucyrus-Erie sold quite a few of them.Bucyrus-Erie did well in maintaining consistently good sales against all those other suppliers.Subscribe my Newsletter for new blog posts, tips & new photos.
