An international corporation with a wide range of industries and a network of representative offices around the world. Since acquiring Daewoo Heavy Industries & Machinery in 2005, Doosan has also focused on the construction equipment market.
Then it all started with excavators and wheel loaders. Now the South Korean company Doosan ranks 8th in the world in the production of earthmoving and road construction equipment.

The company’s annual turnover is $ 11 billion. As a result of the transformation, Doosan is progressively pursuing a strategy to achieve leadership in its segment. In 2015, it was ranked 10th in
the world in the production of construction equipment, and in 2016 it climbed 2 levels higher and took 8th place. Doosan expects to become the world’s third largest manufacturer of construction
machinery and equipment after Caterpillar and Komatsu, with annual
sales of $ 12 billion.

The company’s products are excavators, consumer goods, real estate, financial services, IT services, media, retail, industrial equipment and consulting.

In 1977, Daewoo Heavy Industries was established as a division of the South Korean corporation Daewoo. Collaboration with Hitachi launched the production of crawler excavators, which led to the
in-house production of the Solar range after 8 years.

Doosan bought Daewoo Heavy Industries in 2005, which allowed it to strengthen its position in the construction equipment market. Since that time, all equipment began to come under the
Doosan-Daewoo brand. But in 2007, it was decided to promote the technique only under the Doosan brand.

It is worth noting that Doosan Corporation produces a wide range of products, from food and beverage products to engines, heavy equipment and power plants. The construction equipment is handled
by the Doosan Infacore division.

Doosan Infacore is a global corporation with a wide range of industries and a network of representative offices around the world. As noted, the company acquired Daewoo Heavy Industries &
Machinery in 2005, allowing Doosan to enter the construction machinery market. It all started with the release of Doosan excavators and front loaders. At the end of 2010, the South Korean company
ranked 6th in the world in the production of earthmoving and road construction equipment.
