include the R 9100 up to the R 9800 . An electric Liebherr R 9400 was last year put into operation at the Vostochny coal mine of ERG in Kazakhstan for waste stripping . The new excavator is equipped with a bucket size of 22 m 3 . Other investments at the mine include eight new Caterpillar 789D haul trucks . Liebherr has delivered over 60 electric shovels over a period of 30 years in both face shovel and backhoe and also offers cable reeler solutions . In terms of other carbon reductions options all of its shovel line up can also run on up to 100 % HVO while it is also doing a lot of R & D into the use of e-fuels like ammonia and methanol , hydrogen and battery power in both its trucks and shovels .
In its conventional diesel machines , the newest model is the R 9300 . In January 2023 , Karunia – a Liebherr Indonesia customer – signed an agreement for the purchase of four additional units of the R 9300 mining excavator for Tabang coal mine , located in the Kutai Kartanegara Regency of East Kalimantan , Indonesia . These four excavators will be delivered from late 2023 to early 2024 and will join the R 9300 pre-series unit that has been on site since September 2022 .
PT Karunia Armada Indonesia ( Karunia ) has agreed to increase its existing mining fleet with four of Liebherr Mining ’ s latest 250 t class excavator : the R 9300 G8 . Karunia received a pre-series unit of the R 9300 in September 2022 as part of the development and validation process for the mining excavator .
During the development and validation process , Karunia provided direct and transparent feedback about its Liebherr fleet . This helped Liebherr to better understand the role that its technology played in supporting customers ’ daily activities . After a few months in operation , the figures provided to Liebherr by Karunia have proven that the R 9300 G8 matches Karunia ’ s requirements during its operations .
Liebherr says Karunia has observed the high performance of the R 9300 since its arrival on site in September 2022 , further solidifying its decision to expand its R 9300 fleet . “ The company has expressed that the performance of the R 9300 G8 has been staggering and surpassed all expectations . The excavator has helped Karunia to achieve its ever-increasing production targets . Karunia has also articulated that the best things about the preseries unit they received were the comprehensive services and the quick response times from Liebherr Indonesia .”
Liebherr Mining and Karunia established their partnership in 2021 , with the delivery of an R 9100 mining excavator to the Tabang mine . Since that time , Karunia ’ s fleet of Liebherr machines has increased and now includes an R 9200 , the pre-series R 9300 , and two PR 776 mining dozers . The steady growth of Karunia ’ s fleet of Liebherr equipment , including their purchase of four more R 9300 units , “ represents Karunia ’ s faith in Liebherr ’ s ability to deliver products that provide exceptional results .”
Karunia originally chose Liebherr Mining products for their competitive availability and terms , offered during a time of uncertainty . Further , Liebherr ’ s product support – directly backed by the OEM – is a unique structure in Indonesia . “ Karunia chooses to continue to work with Liebherr Indonesia due to the encompassing measures the company takes to support Karunia ’ s growth after the sale of the equipment .”
Karunia is a mining contractor headquartered in Balikpapan , East Kalimantan . In 2011 , Karunia expanded into surface mining when the company was offered a contract by PT Bayan Resources Tbk to haul coal and overburden within the Tabang mine site . Since this contract was established , it has been Karunia ’ s goal to increase coal production on site to meet Bayan ’ s requirements . Liebherr ’ s R 9300 will play a crucial role in increasing the efficiency of Karunia ’ s operation .
The R 9300 G8 – unveiled at the Bauma exhibition in Germany last year – is the latest mining excavator to join Liebherr Mining ’ s portfolio . The new R 9300 is the second Generation 8 excavator launched within the portfolio and is fitted with the most advanced Liebherr Mining technologies , building on Liebherr ’ s decades of expertise designing excavators for the mining
