1888
Heinrich Baumann establishes a haulage business in Engelskirchen. Back then, goods are still being transported around the mountainous region of the Bergisches Land (in North Rhine-Westphalia) on horse-drawn carts. But the entrepreneur realises early on that business advancement lay in the expanding urban areas.

1914
He moves the haulage company to Bonn.

1918
Three of his sons are working with him in the business. Clay and glass are transported from the areas surrounding Bonn to the Rheinhafen docks. Later, the horses are replaced by caterpillar trucks.

1933
Heinrich's son Viktor Baumann takes over the company from his father. The first modern-design trucks are purchased. The vehicle fleet is steadily expanded.

1939
The fleet comprises 8 trucks and 25-30 trailers. When war breaks out, half of the fleet is confiscated and used for war purposes.

1944
Christmas: The company site and the entire fleet of vehicles are completely destroyed in a bombing raid. In just one night, 12 bombs rain down on the company premises.

1945
Rebuilding starts after the war. The new fleet of vehicles is assembled from the military vehicles that are no longer needed. The transported goods are primarily clay and aluminium.

1948
Bonn becomes the Federal capital of Western Germany. Construction machinery and materials are needed to build the new capital. A military low-loader is converted to become a civilian vehicle. BAUMANN starts up its HEAVY TRANSPORT business.

1950
The first own-design mobile crane is constructed. A crane is mounted onto an American military vehicle.

1957
The first new truck-mounted crane is purchased: a PH lattice boom crane capable of lifting 20 t.

1961
Viktor's son Rudolf Baumann becomes manager of the company. Under his guidance, the company develops into one of the leading heavy transport and crane companies in Germany.

1974
The company expands to the point where the space constraints in the centre of Bonn make a move to an outlying district of the city essential. Today, the company site in Bornheim-Hersel, to the north of Bonn, comprises an area of 70,000 m2.

1990
A branch is established on a 20,000 m2 site in Leipzig.

2009
Rudolf's daughter Sabine Baumann-Duvenbeck joins the board. Today, the company employs over 120 staff.
