Muir-Hill

Muir Hill products included basic petrol engined locomotives, mainly for narrow gauge. The early locos were little more than a Fordson tractor skid mounted on a rail chassis, with a chain connecting the rear axle of the tractor to the rail wheels. Production of locomotives did not continue beyond the 1930s; the company went on to build heavy tractors and construction equipment.

Muir-Hill moved on to producing dumpers also based on Fordson tractor skid units. They also built forklifts based on a tractor skid unit for a period before other manufacturers entered the market with better machines, and built some of the earlier articulated dumpers that evolved into the modern ADT.  Muir-Hill later moved into tractor production which continued until the 1980s.

The company name and manufacturing rights transferred hands a number of times, first to E. Boydell and Co, then Winget, then Babcock & Wilcox , then Aveling-Barford, then to Lloyd Loaders (MH).

Muir-Hill tractors have survived longer than comparable models, and a number have been subject to restoration. Threlkeld Quarry Museum holds examples of Muir Hill equipment. The Ravenglass & Eskdale Railway has two examples.

DROTT - IH (Jumbo Sicam, France)

Society de Industrial Construction of Mechanical Hydraulic Appliances (SICAM) 
Drott was the sole supplier of loader attachments for International Harvester crawler tractors in the 1950s, until International introduced their own line of integral loaders.

Edward Drott founded Drott Tractor Company in his home town of Butternut, Wisconsin, in 1916. It was moved to Wausau, Wisconsin, in 1923. In 1924, it was reorganized as Hi-Way Service Corporation and relocated again, this time to Milwaukee, Wisconsin. 
Hi-Way Service designed a snow plow as a joint venture with Wausau Iron Works. Hi-Way Service became Drott Manufacturing Company, and returned to Wausau.

In 1962, Drott purchased American rights to the Yumbo hydraulic backhoe produced by Sicam of France. 
(Society de Industrial Construction of Mechanical Hydraulic Appliances = SICAM)
In 1968, Tenneco Corporation purchased Drott and made it a division of Case Corporation (Collection 227), which it also owned.
Shuttlelift, Inc. (collection 1369) acquired the Carrydeck line of industrial hydraulic cranes from Drott Manufacturing Company (Collection 376). Shuttlelift was acquired by Marine Travelift, who sold the Carrydeck line to The Manitowoc Company, Inc. (Collection 15) on January 5, 2007.

Model nomenclature:
Drott was the sole supplier of loader attachments for International Harvester crawler tractors in the 1950s, until International introduced their own line of integral loaders. 
It developed the first multi-purpose bucket; dubbed the 4-in-1 bucket, it gets its name from its four functions: Dozer, clamshell, bucket and scraper. 
The 4-in-1-line became the basis for International Harvester's crawler loader line.

Drott model numbers had a prefix that matched the model number for the tractor; i.e., the TD6 used a 6K3 loader. An “A” suffix indicated a later improved version.

Drott oli ainoa kansainvälisten Harvester-telaketjutraktoreiden kuormauslaitteiden toimittaja 1950-luvulla, kunnes International esitteli omat kiinteästi asennetut kuormaaja sarjansa.

Edward Drott perusti Drott Tractor Companyn vuonna 1916 Butternutin kotikaupungissaan Wisconsinissa. Se siirrettiin Wausau, Wisconsin, vuonna 1923. Vuonna 1924 rakennettiin uudelleen Hi-Way Service Corporationiksi ja siirrettiin uudelleen, tällä kertaa Milwaukee, Wisconsinissa.

Hi-Way Service suunnitteli lumiauran yhteisyritykseksi Wausau Iron Worksin kanssa. Hi-Way Serviceista tuli Drott Manufacturing Company ja palasi Wausauen.

Vuonna 1962 Drott osti Amerikan oikeudet Ranskalaisen Sicamin tuottamalle Yumbo-hydrauli kaivureiden sarjalle.
Vuonna 1968 Tenneco osti Drottin ja liitti sen Case Corporation (Collection 227) divisioonaan, jonka myös omisti.





Shuttlelift, Inc. (kokoelma 1369) hankki Carrydeckin teollisuushydraulinostureiden linjan Drott Manufacturing Companyn (Collection 376). Shuttlelift osti Marine Travelift, joka myi Carrydeck-linjan The Manitowoc Company, Inc: lle (Collection 15) 5. tammikuuta 2007.

Mallinimikkeistö:
Drott oli ainoa kansainvälisten Harvester-telaketjutraktoreiden kuormauslaitteiden toimittaja 1950-luvulla, kunnes IH esitteli omat kiinteästi asennetut kuormaajat.

Se kehitti ensimmäisen nelitoimi-kauhan jota kutsutaan 4-in-1 kauha, se saa nimensä sen neljästä käyttömahdollisuus toiminnosta puskuri, simpukka, kauha ja kaavin.
4-in-1-linjasta tuli IH, eli International Harvesterin tela-kuormaajien sarja.

Drottin malli-numeroilla oli etuliite, joka vastasi maatalous-traktorin mallinumeroa ts. TD6 käytti 6K3 kuormaajaa. "A" -pääte osoitti myöhemmin parannettua versiota.
