This summer，As a 250-ton classR 9250 updated model——Liebherr's eighth generation (G8)The latest mining excavatorR The 9300 is now officially on sale.。The second excavator in the Liebherr range, Generation 8，It adopts Liebherr's new cross-era technology.。The new technology gives the machine better field performance，And with the auxiliary system of Liebherr，Automation、Zero emission technology，And better compatibility of digital services。In 2024，R The 9300 will go into mass production.。

Efficient transmission system：25% more fuel efficient%

More environmentally friendly electric drive systems are also under development.

Liebherr Energy Efficient System (LPE) Is a proprietary engine and hydraulic management system，YesR Standard on the 9300。LPEThe support helps reduce the fuel consumption of the machine.，While maintaining peak productivity and performance。R The 9300 and its predecessorsR Compared to 9250，Fuel consumption is reduced by 15 percent%，The reduction in fuel consumption can also makeR The 9300 is 25% more fuel efficient%。

 Up to 15% reduction in fuel consumption%

It is worth mentioning that，Liebherr is developingR At the beginning of 9300，Not only considering the improvement of transmission efficiency，Considerable reductions in the level of carbon emissions need to be taken into account，R The engine carried by 9300 has international high specifications.FCOAnd AmericaEPA Tier 4/EU Stage V (AdoptSCRPost-processing technology) Version of Strict Certification，To meet commitments to reduce emissions.。

At present，R An electric drive version of the 9300 is in development，And will be launched in the near future。

Innovative design

Improve the working device、Longer service life and improved operating comfort

Bucket capacity is increased

With the previous generationR Compared to 9250，R The 9300 features an updated work unit design，ThanR The 9250 is lighter、Stronger。The new working device is equipped with high-performance components.、Aluminum cover plate，New design of boom and stick，All of the above upgrades are factory standard。This streamlined design，Increased bucket capacity for backhoe and front shovel configuration。

Standard bucket is 16 in backhoe configuration.5 cubic meters，16 cubic meters in the front shovel configuration（Use a heavy-duty wear kit，Applicable material density 1.8 tons/Cubic），This allows the excavator to be used efficiently with a rated load of 100 tons.、130 ton and 180 ton trucks to match.。

And the service life is prolonged

The new design also simplifies maintenance and extends service life。This excavator shares parts with Liebherr's current excavators.，To help minimize maintenance costs and on-site inventory。R Service life ratio of 9300R 9250 increased by 33%，From 45,000 hours increased to 60,000 hours。ExtendR The service life of the 9300 helps this machine to better align with the service life of the excavator's major components。

Optimize the operation

Further improvements can be made in theR Found in the cab design of the 9300。The new cab includes enhanced cab ergonomics，Larger touch screen，New Control Panel Design，And optimized field of view，To help promote operator health，While improving security。

Indonesian “Actual combat” Experience

Validate high efficiency and productivity

AsR Part of the 9300 Validation Phase，Liebherr and its customersPT Karunia Armada Indonesia (Karunia) Carry out in-depth cooperation，Test the capability of the excavator in the field。KaruniaIs a mining contractor based in East Kalimantan, Indonesia，It will be used in September 2022.R 9300 Test Engineering Prototype，AtTabangExcavation and loading in the mining area，It mainly matches trucks with 100 tons and 130 tons.。

For further proofR The ability of 9300，March 2023，TabangThe production monitoring and inspection of the test prototype were carried out in the mining area.。During the expedition，R The 9300 achieved an average cycle time of 26 seconds.，Helped the excavator reach 1371 cubic meters per hour. (3017 tons) Instantaneous production rate。For a 250-ton excavator，This is an impressive result.。R The 9300 also achieved a loading capacity of 9 per liter of fuel.22 solid square (BCM) Fuel efficiency。

R The 9300 will enter volume production in 2024.，Backhoe configuration available from Q1，Face Shovel Configuration Available Q2。
