Overview of Top 5 Largest Hydraulic Excavators used in 2019. Let’s have a look together and discover which excavator is the biggest of them all.

Also called tracked excavators, crawler excavators are the core of every heavy machinery fleet in the construction industry. A crawler excavator is suitable for a wide range of jobs such as excavating, landscape digging, mining, civil engineering, pipe jacking or even demolition, making it one of the most important machines on the construction site.

The versatility of crawler excavators can be also improved with hydraulically-powered attachments, typically buckets, pulverizers, breakers, crushers, shears, hammers, grapplers or tiltrotators. Utilizing the tracks, these heavy-duty machines are well-equipped to handle work in a challenging environment, however, the tracks limit their movement speed.

Komatsu PC8000 is the world’s fifth largest hydraulic excavator and the biggest mining excavator in the Japanese manufacturer’s product portfolio. Komatsu has recently introduced a new version called PC 8000-11, which is based on popular PC 8000-6. This giant is offered in both backhoe and front shovel configuration, weighing up to 773 tons.

Hitachi states that one-third of all hydraulic mining excavators across the world are Hitachi. Launched in 2012, the EX8000-6 is the largest Hitachi mining excavator and the third biggest excavator in the world, weighing up to 837 tons. The durable machine can be fitted with 40 m3 load shovel or 43 m3 backhoe bucket, which are designed to load Hitachi EH4000AC-3 dump truck in three passes or the largest Hitachi dump truck EH5000AC-3 in five passes. The EX8000-6 is equipped with two Cummins QSK60C engines, each rated at 1450 kW/1944 HP. The excavator features maximum digging depth of 13.8 m and digging force of 2230 kN.
Operating weight 825–837 ton
Engine power 2x 1450 kW / 1944 HP
Shovel capacity 40 m³ / 55.3 yd3
Backhoe capacity 43 m³ / 56.2 yd3
Breakout force 2230 kN


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 9900 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 3360 kW/4500 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 1680 kW / 2250 HP
Shovel capacity 50 m³ / 65.4 yd3
Breakout force 2400 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 1000 tons. The goliath is equipped with two Cummins QSK60 engines, rated at 3360 kW/4500 HP in total. The 52 m3 bucket has payload of 93,6 tons and it takes just 4 passes to load the largest Caterpillar dump truck, the 797.

Operating weight 1000 ton
Engine power 2x 1680 kW / 2250 HP
Shovel capacity 52 m³ / 68 yd3
Breakout force 2400 kN
