Compact and Fuel-efficient
<span style="font-weight: bold;">Three Liebherr R 920 crawler excavators have been working successfully in a South African mine.</span> <p></p><p> KEDASE, based in Boshoek, South Africa and active in mining, purchased three R 920 crawler excavators from Liebherr in 2016. The compact dimensions of the machines and their fuel efficiency were key factors in the decision-making process. And after more than 1,000 operating hours, these criteria still hold true.</p><p>The three Liebherr R 920 crawler excavators are used for trenching, pipe laying and for the feeding of a screener in a chromium mine. With an operating weight of 21 tonnes and equipped with a Stage IIIA/Tier 3/CHINA III engine with an output of 110 kW/150 HP, the R 920 crawler excavator was developed specifically for these types of applications. For KEDASE, the machines have been configured with a 5.7 m boom, a 2 m stick and a 1.15 cu m bucket.</p><p>The R 920 concept is based on the standard European models with high levels of reliability and increased productivity combined with low fuel consumption. Launched onto the market at bauma 2016, the R 920 is accompanied by a revamp of the range of 20 to 25 tonne crawler excavators. In addition to the R 920 are the R 922 and R 924. The R 922 weighs 22 tonnes and has an output of 110 kW/150 HP and the R 924 weighs 24 tonnes and has an output of 125 kW/170 HP. These machines are aimed at less regulated markets like South Africa, South East Asia, Russia, China and India.</p><p> <span style="font-weight: bold;">Performance meets expectations</span><br />Since their arrival in 2016, the R 920 crawler excavators have met all expectations. After more than 1,000 operating hours, these machines are currently used for 9-12 hours every day with an average fuel consumption of only 15 litre/hour. The manoeuvrability and hydraulic performance in particular make the machines efficient on site. From the operator's point of view, the R 920 is characterised by its speed, comfort, stability and performance: &quot;I feel like I'm in a pickup,&quot; said the operator with pride. </p><p>For <span style="font-weight: bold;">Ofentse Sekano, KEDASE's Managing Director, </span>the partnership with Liebherr is certainly on the right track. &quot;With the expectation that these machines will keep performing over time and reach 15,000 operating hours, he will certainly be choosing Liebherr again in the future.&quot;</p>
