Excavators are self-propelled machines whose function consists of digging with a bucket or several buckets. As such, works usually development of rocks or loading bulk materials. Excavators are equipped with both tracked and pneumatic wheeled chassis, although large models are practically always have a tracked track. This type of technology is wide variety in terms of size: from fairly compact models, which can often be seen on urban sites and to the present giants commensurate with high-rise buildings. Similar huge cars surprise not only with their appearance, but also with that scale works with which they regularly cope. Present you ten the world’s largest excavators.

Power Hitachi EX8000-6 reaches 3880 horsepower. 40 bucket cubic meters with an effort of 2230 kilonewtons in just one the rise can extract 75 tons of rock from the earth, and in three aisle – fully load a large dump truck. The machine has a huge margin of reliability, allowing operation all day long. Her working resource is about 90 thousand hours.

6th place – Terex RH400

Rating: 4.

Terex RH400

The American company Terex has developed the RH400 model for the implementation of complex and voluminous work in deep quarries. It is the largest hydraulic excavator in the world, and it leading in terms of performance. Mass machine 980 tons creates a pressure of 25.8 newton per square centimeter the soil. Dimensions no less impressive: the length of the giant 26 and a half meters, height – a little less than 14 meters. For movement a tracked platform is used, each of the two pairs of tracks has 8.6 meters wide. The excavator is equipped with a pair of common engines with a capacity of 4600 horsepower. They can withstand around the clock work until the fuel tank runs out of 15 thousand liters the fuel that it holds. 50 cubic machine bucket It weighs 65 tons, it is capable of lifting up to 100 tons of cargo. Thus, only four loading cycles are needed for filling a large mining truck. Per hour Terex RH400 produces a record 10 thousand tons of rock.
