Menck & Hambrock (often shortened to Menck ) was a German mechanical engineering company based in Hamburg-Altona , which manufactured excavators in particular.
history
Steam excavator
The company was founded in 1868 by Johannes Menck and Diedrich Hambrock in what was then the village of Ottensen . She initially worked in boiler and steam engine construction before the first excavator was constructed in 1888 . Even before the First World War , Menck was one of the world's leading excavator manufacturers. In 1901, for example, the plant presented the world's first own shovel excavator. Menck & Hambrock had a special permit from the Royal Prussian and Grand Ducal Hessian Railway Association to transport large excavators with steam operation, which were permanently mounted on a flat wagon , as railway vehicles. In each individual case, a provisional track was laid from the nearest railway line to the deployment site.
From 1923, the M II, M III and M IV series were the first crawler excavators in Europe.
Diesel excavator
In 1933, in cooperation with Hanomag , the company constructed the first German bulldozer , as well as the successful universal diesel cable excavator series Mo, Ma, Mb, Mc and Md. The excavators shoveled saltpeter in Chile , asbestos in Russian pits, they dug canals in Sweden and moved boulders in quarries in the Canaries . They were used in the construction of the Reichsautobahn as well as in the reconstruction of Germany, which was destroyed by the Second World War.
The piling technology and the development of flat excavator devices (Menck's name for scraper) also took up a lot of space. In 1939, Hugo Cordes developed the world's first scraper with the type designation SR39 . A total of 8 machines of this type were delivered to the engineer troops of the Wehrmacht. In 1943 the SR43 followed as a further development of the previous model SR39 . 30 machines of this type were produced by the steel construction company Benteler (hence the name Benteler-Menck scraper ).
After a large part of the capacity was used for the production of armaments during the Second World War , Menck & Hambrock continued the construction of the urgently needed excavators after the war, initially with the series mentioned above, then from 1948 with completely new designs such as the M152, M75, M60, M250 and M90. Another mainstay of the company in the post-war period were light cranes such as the LK46, the smallest machine type Menck has ever built, and the LK50.
The production of scrapers was also resumed after the war. Under the guidance of Hugo Cordes and Günter Kühn, 24 SR53 machines were initially built annually from 1953 . The Hamburg company later developed even more powerful machines, such as the SR65 and SR85 types . In total, around 350 scrapers had been built in Hamburg before Menck & Hambrock went bankrupt. In addition, scrapers were manufactured on the basis of license agreements in Japan and Switzerland until they were replaced by in-house developments by the respective companies.
Decline
Menck has been one of Europe's most important excavator manufacturers for decades. The longevity of Menck machines is demonstrated by the high number of machines still in operation from the 1950s to 1970s. Since the early 1960s, however, there has been a fundamental change in technology in excavators, away from traditional rope devices to hydraulic excavators that are far more powerful and more precisely controllable in many applications.
The company did not recognize the break time and held too long in the conventional cable equipment fixed, while more innovative manufacturers, especially Orenstein & Koppel , Liebherr , Poclain , Demag and Atlas of hydraulic helped consistently to break through. As a result, Menck lost market share and ran into economic difficulties.
In 1966, Menck was therefore taken over by the US company Koehring , which expanded the Menck range with its American hydraulic excavators, which were already technically overhauled at the time. However, these devices were not competitive against contemporary European hydraulic excavators. Menck's own hydraulic excavators based on advanced European design principles were later developed and offered. But that came too late, the market had meanwhile been lost to other manufacturers, and the traditional company had to file for bankruptcy in 1978 . However, some Menck developments were taken over by other groups (e.g. Liebherr), in particular the last generation of modern Menck duty cycle crawler excavators with hydraulic power transmission and controls that were innovative at the time, formed the basis for the later Liebherr rope machines.
The ramming division was continued after 1978 and operates today as Menck GmbH.
A 15-ton crane that was originally used in the factory in Hamburg-Altona has been the landmark of the Fabrik (Hamburg) cultural facility since 1979 .
