Liebherr R 9600 G8 - World’s Top 10 largest hydraulic excavators

The R 9600 G8 is the newest addition to Liebherr’s mining portfolio that was introduced at MINExpo International 2021. The crawler excavator was launched at the beginning of 2021 after years of development and experience within the mining industry. The model is a successor and the next generation of the popular R 996B model, which is currently not in serial production. The R 9600 was field-tested in Australia and the results revealed that the new generation excavator is 19.6% more productive and faster than its predecessor R 996B. Moreover, the R 9600 has a 40% less fuel consumption compared to R 996B. The white beast is equipped with two QSK50 Cummins engines rated at 2,500 kW, US EPA Tier 4f / EU Stage V compliant. Liebherr also plans to offer an electric drive version. The new Generation 8 features many technological features such as on-board assistants, redesigned cab or enhanced undercarriage. First 11 units of the R 9600 G8 were delivered last year to customers in Australia, where they will work in coal mines.

The XE7000 is considered the biggest Chinese excavator. China therefore entered the 700-ton mining excavator sector as the fourth country after the USA, Japan and Germany. Model XE7000 weighs 673 metric tonnes that are powered by two 1,193 kW (1,600 hp) engines. The maximum digging force of 167 tonnes (1640 kN) secures high performance. The XE7000 excavator is equipped with a 34 m³ bucket that is capable of holding around 50 t of coal with each scoop. Speaking in numbers, if this excavator would work all-day-long it would be able to load about 30,000 t of coal per day. Therefore, the XE7000 is designed to work in pairs with the largest dump trucks that have a loading capacity of 300-400 tonnes. The machine also requires a lot of space as it is 23.5 meters long. Moreover, XCMG also offers the XE7000E which is a version powered by two electro-hydraulic motors. The powerdrive delivers 2,500 kW (3,350 hp) in total. This version is a little bit lighter than the XE7000 as it weighs 660 t. The electro-hydraulic version can be equipped with even larger buckets that offer a maximum digging force of 2,270 kN and therefore the best performance.

Operating weight (XE7000 / XE7000E)	673 t / 660 t
Engine power	2x 1,193 kW (1,600 HP) / 2x 1,250 kW (1,676 hp)
Max digging radius	21.19 m / 16.7 m

The RH 400 is currently the second largest hydraulic excavator in the world. The behemoth was first launched as Terex RH 400 in Germany in 1997. Just one year later, Terex acquired the O&K Mining and added its company name into the model name. However, Terex sold its mining division to Bucyrus in 2010 and the model was renamed to Bucyrus RH 400. The excavator is able to scoop up around 9,900 tons of material every hour, setting a new world record for a hydraulic mining excavator. The 50 m³ shovel is over 6 m wide, weighs 84 tons and is able to hold 85 tons of material in a single scoop, which can easily fill any mining truck in 3-5 passes. The RH 400 is powered by two engines with total 3,360 kW/4,500 HP and it requires 6 car-batteries just to start the engines that produce max. travel speed of 2.2 km/h.

Operating weight	980 ton
Engine power	2x 1,680 kW / 2,250 HP
Shovel capacity	50 m³ / 65.4 yd³
Breakout force	2,400 kN

The world’s largest excavator is currently Caterpillar 6090 FS. The model is based on Bucyrus RH400, because Bucyrus was purchased by Caterpillar in 2011, expanding its mining division. However, the 6090 FS features more durable components, hardened undercarriage, enhanced oil-flow system and hydraulics, better customer service support, LED working lights for night shifts or innovative on-board electronics. The weight of Cat 6090 FS mining excavator reaches an incredible 1,000 tons. The goliath is equipped with two Cummins QSK60 engines, rated at 3,360 kW/4,500 HP in total. The 52 m³ shovel has a payload of 93.6 tons and it takes just 4 passes to load the largest Caterpillar dump truck, the 797.
