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
