Doosan DX225LC-5 is learning to swim in front of Sylt

So that the company Sven Jacobs Tief-, Garten- und Landschaftsbau in Tating (Schleswig-Holstein) can carry out a series of work in the Wadden Sea, especially on the Hindenburg dam, the dedicated 22-tonne crawler Doosan DX225LC-5 had to learn how to swim. This has been achieved by the machine purchased from the Doosan dealer Atlas Hamburg by the company OLKO from Olfen (NRW) was converted to an amphibious machine.

The main application area for the new excavator is the approximately 11.3-kilometer-long Hindenburgdamm, which connects the island of Sylt with the mainland. Approximately 8.1 kilometers of the Hindenburg embankment run through the Wadden Sea. In order to prevent the standard 22-tonne crawler from sinking into the watt, a particularly low ground pressure is required. For this purpose, Jens Mewes, Sales Atlas Hamburg, who has been serving the customer Jacobs for four years, established contact with the company OLKO. There, the superstructure of the Doosan DX225LC-5 was mounted on an amphibious undercarriage. Unlike a standard pontoon so the full maneuverability is maintained.

Individually adapted to customer requirements

The company Jacobs has been relying on Doosan excavators since 2014, so the new machine is already the fifth Doosan brand of crawler excavators. The DX225LC-5 features the same new distinctive engine design that characterizes all the excavators of the new Doosan LC-5 generation and is powered by the proven water-cooled Doosan 6-cylinder DL06P 6-cylinder turbo diesel that delivers 124 kW (168 hp) 1800 rpm. This therefore combines sufficient power with high torque at a lower speed.Doosan DX225LC-5

The design of the OLKO undercarriage is designed for difficult applications in adverse conditions and unsustainable surfaces, so that they can withstand extreme conditions and requirements in, for example, wetlands, as well as perform environmentally friendly work in sensitive environments. It also makes it possible to carry out work on lakes, rivers and coastal areas. The type U / 1800 used undercarriage has a length of 10.80 m, a width of 6.20 m and a height of 2.35 m. The undercarriage alone weighs around 27 tonnes and produces a buoyancy of 580 kN. It achieves a load capacity of 18 tonnes and a maximum speed of 4km / h.

In addition to the conversion of the chassis, a number of other modifications were made by the company OLKO. So the crawler excavator got a boom with 9 m and a dipper stick with 6 m length. The extended reach makes it possible to work underwater without any problems. In addition, an additional fuel tank and a shelf for an anchor were installed. In order to comply with environmental regulations, the machine was converted to biodegradable Panolin hydraulic oil. The resulting new machine was given a CE mark by OLKO and received the documentation corresponding to the Machinery Directive.

Since the founding of the company in 1989, OLKO-Maschinentechnik GmbH from Olfen has been one of the driving forces in the field of shaft construction and conveying technology. With mining in the region declining sharply in recent years, the company has been looking for new business opportunities that promise long-term growth. As part of this process, OLKO first concentrated on an amphibious machine on a niche in the construction machinery segment. Introduced for the first time at Conexpo 2017, the company has now also implemented a first project in Germany with the conversion of the Doosan DX225LC-5.
