Bruneri "Yumbo" S25

The Yumbo Company a French Firm was formed around 1954, based on worldwide patent rights of a hydraulic excavator design. Initial production was a truck mounted excavator called the S25. In 1948, a wheeled prototype of the excavator was developed by Carlo and Mario Bruneri of Italy. 

This was the first fully hydraulic excavator and Yumbo or SICAM 
(Society de Industrial Construction of Mechanical Hydraulic Appliances)
bought the patent rights in 1954. 
Some say the Gradall of 1941 was the first hydraulic excavator built in Ohio. 
This was built a little different than the Yumbo with a boom that moved in and out. It was also mounted on a truck. A lot of highway departments used them
The first self propelled hydraulic excavator the model H24 was developed in 1956.

These are simple truth
This was a rubber tired machine. In 1957 Yumbo brought out the biggest hydraulic excavator in existence at the time, the model Y500 (19Ton). 

This machine was mounted on tracks. In 1962 the Genos plant was built. The model Y45 (crawler machine) and the model H45 (rubber tired under carriage) were introduced in the French market.  Text by

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.

Hydraulic era
In 1954, Demag developed their first hydraulic excavators. Demag would soon expand into construction machines, vehicle cranes, moving and conveying engineering (workshop crane and control devices), steel mill technology (complete metallurgical plants, in particular continuous casting equipment), compressors, and compressed air engineering.
