Presentation of the company TKO d.o.o.

The company Tovarna kovinske opreme d.o.o. is a manufacturer of various components and component groups for construction equipment, predominantly excavators, bulldozers and loaders. Approximately 96 % of our turnover is created in EU markets with foreign clients such as Liebherr, Caterpillar (formerly Bucyrus Werk Dortmund), Epsilon, Putzmeister and others.

On 31 December 2019, TKO d.o.o. has employed 203 workers.

Our products

Our products include:
- excavator arms in lengths from 2 m to 15 m and weighing between 300 kg and 16000 kg,
- components for mobile cranes,
- fuel tanks,
- hydraulic oil tanks,
- bulldozer chassis-housings,
- loader frames,
- bulldozer blades,
- various smaller components.


Our manufacturing process consists of the following areas:
- procurement of materials and storage,
- production of semi-finished products: cutting with CNC plasma and flame torches, band saws, hydraulic scissors, preparation of welding surfaces, sheet metal bending, drilling, automatic and manual sand blasting, milling,
- assembly of semi-finished products into subassemblies and finished products,
- welding,
- machining,
- finalization with welding of various small elements such as brackets, carriers, hydraulic pipe holders, etc,
- painting of finished products.

The company is investing great assets into modernization and development. In early 2006 a new CNC milling machine was put into operation. In the autumn of 2006 a new painting booth was finished in order to meet new EU standards regarding environmental protection. In early 2007 a new CNC milling center was commissioned for machining smaller components. A new 4000 m2 production hall was constructed in late 2007 and in early 2009 a new 6 m 1000 ton press was installed. In the beginning of year 2016 we purchased a new CNC cutting machine. The machine has a cutting table which is 30 meters long, and has two portals that enable flame cutting and 3D plasma cutting (used for bevelling edges as a means of weld preparation).

The company has approximately 9000 m2 of production space, equipped with cantilever cranes (load capacity up to 1000 kg) and gantry cranes (load capacity up to 20000 kg).

The majority of our equipment allows us to construct larger and more demanding products with greater added value, but our production of higher priced products is somewhat limited by our milling equipment.

The structure of our employees adapts to the development of technology. It depends greatly on the employment market where there is a marked lack of trained metalworkers, especially welders, mechanics, machine technicians and technologists.
