Demag exavator

Demag Cranes AG is a German heavy equipment manufacturer now controlled by US based Terex. 

The roots of Demag date back prior to its formation, but became Märkische Maschinenbau-Anstalt, Ludwig A.-G in 1906 as the biggest crane building company in Germany employing 250-300 people. 

In 1954, Demag developed their first hydraulic excavators. 

The company was a manufacturer of industrial cranes that included types like, bridge cranes, hoist (device), overhead cranes, Gantry crane to name a few.

Starting in 1925, Demag also manufactured excavators. They expanded to manufacture locomotives and railroad cars. During the Second World War, armoured fighting vehicles (in particular Bergepanther) were built in the Berlin Staaken plant.

During the buildup to, and during World War II, Demag-designed halftrack military vehicles, both in unarmored "artillery tractor" models in the late 1930s, the basis for the powertrain of their armored Sd.Kfz. 250, which itself played an important role during the war, with just over 6,600 built by Demag and their subcontractors.
