PRODUCT FOCUS suited to offer clients the expertise and advice on the machinery requirements, to offer a total solution with the inclusion of a warranty on both machine and attachment, making Maximum a one-stop shop for parts and backup. The HMK 490 LC HD complements the Hidromek product range, which already includes excavators from 14 tonne to 51 tonne, and includes the class-leading TLBs. Maximum Equipment will also be expanding their product range later in the year with the launch of the new loader. About Maximum Equipment Maximum Equipment started operations in 1997 with the sale and marketing of quality used equipment. In 2005, Maximum Equipment expanded into the plant hire market, specialising in excavators and attachments, most notably hydraulic hammers. In 2006, Maximum Equipment secured the sole dealership for southern Africa for the Komac brand of hydraulic attachments and hammers. Komac, based in Korea, is a leading manufacturer of hydraulic breakers and attachments. Later in 2006, Maximum Equipment added Torpedo, another quality Korean attachment manufacturer to their range. ‘All-terrain’ conversion for Doosan A new special ‘all-terrain’ conversion on a Doosan DX225LC-5 crawler excavator means tailor-made efficiencies. A new 22 tonne Doosan DX225LC-5 crawler excavator has been converted into an ‘all-terrain’ machine for contracts being carried out in the Wadden Sea in Germany, by the company Sven Jacobs Tief-, Garten- und Landschaftsbau, based in Tating (Schleswig-Holstein). The conversion of the Doosan excavator supplied by local Doosan dealer, Atlas Hamburg GmbH, was completed by OLKO-Maschinentechnik GmbH from Olfen (NRW). The main application area for the new all-terrain excavator is the approximately 11.3km-long Hindenburgdamm embankment, which connects the island of Sylt with the mainland in Germany. Around 8.1km of the Hindenburg embankment runs through the Wadden Sea. To prevent the standard Doosan 22-tonne crawler excavator from sinking into the water, a particularly low ground pressure is required. For this purpose, OLKO-Maschinentechnik was approached to carry out the conversion needed. OLKO has mounted the superstructure of the Doosan DX225LC-5 on an all-terrain undercarriage, not a standard pontoon, to ensure that the full manoeuvrability of the excavator has been maintained. Jacobs has been using Doosan excavators since 2014 and the new machine is the fifth Doosan crawler excavator they have purchased. The DX225LC-5 features the same new distinctive engine design that characterises all the excavators in the latest Doosan LC-5 generation and is 24 MARCH 2019 a buoyancy of 580kN. 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 OLKO. This included fitting the crawler excavator with a 9m boom and a dipper stick 6m in length. The extended reach makes it possible to work underwater without any problems. In addition, a supplementary fuel tank and a shelf for an anchor were installed. To comply with environmental regulations, the machine was converted to biodegradable Panolin hydraulic oil. OLKO ensured that the finished machine is certified with the CE mark and accompanied by the documentation required by the EU Machinery Directive. Individually adapted for customer requirements powered by the proven water-cooled Doosan 6-cylinder DL06P turbo-charged diesel engine that delivers 124kW (168hp) at 1 800rpm. This provides more than enough power and high torque at a lower speed. The OLKO undercarriage is designed for difficult applications in adverse conditions and on challenging surfaces, such as those found in, for example, wetlands, as well as performing 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 undercarriage used on the Doosan DX225LC-5 has a length of 10.80m, a width of 6.20m, and a height of 2.35m. The undercarriage alone weighs around 27 tonnes and produces The main application area for the new all-terrain excavator is the approximately 11.3km-long Hindenburgdamm embankment, which connects the island of Sylt with the mainland in Germany. www.plantonline.co.za
