Electric Liebherr R 9400 at ERG Vostochny
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 preseries 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 pre-series 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 industry . The R 9300 will replace the R 9250 within Liebherr ’ s portfolio once the new model enters serial production in 2024 .
Liebherr is also set to deliver 17 units of dozers and excavators to Erdenes Tavan Tolgoi in Mongolia as part of a recently signed agreement with Monnis International , a large technology and equipment supplier within the country ’ s mining industry .
The deliveries to Erdenes Tavan Tolgoi , a longterm customer of Monnis , are taking place throughout 2023 and 2024 . Liebherr and Monnis signed the agreement during the Bauma 2022 trade fair in Munich , Germany . Monnis was founded after signing a distributorship agreement with Nissan Motors Co in 1998 , but the company quickly diversified from an automotive dealer to cover a wide range of industries – including the mining sector – and , in 2002 , became an official Liebherr dealer .
This most recent supply contract is for a total of 17 Liebherr mining machines , comprised of eight excavators – three R 9250s , two R 9400s , and three R 9600s – and nine PR 776 dozers . These machines are to be delivered to the Tavan Tolgoi coal mine .
To ensure the fast and reliable delivery of after-sales services for Liebherr machinery , Monnis opened its Gobi branch in 2011 , located approximately four kilometres from the Tavan Tolgoi coal mine . With the opening of this branch , those working with Liebherr equipment have access to spare parts , highly trained technicians , and a range of Liebherr mining products to meet the needs of any scenario that may arise on site , Liebherr says .
The new Liebherr excavators and dozers will support the existing Liebherr machinery on site , which includes two R 9200s and one R 9350 .
Moving to Liebherr operator assist functions , they include the Truck Loading Assistant which notifies the operator of the pass loading strategy , the loading tendency and indicates the actual payload per pass before it is loaded into the truck . It assists the operator to obtain target truck payloads consistently with confidence by
