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.
