These machines are manufactured by the well-known brand Komatsu, and in this article we have compiled the ranking of the 5 largest in the world today.
If, since the beginning of time, man has devoted efforts and imagination to the development of increasingly efficient machinery, it has obviously been with the aim of replacing human power with mechanics, making work less tiring. Also, secondarily and consequently, to be able to carry out larger works and in less time.
Excavators or backhoes are articulated vehicles created in order to carry out different types of excavations. These machines are also destined to carry out work of weighing pipes, drains, and other tasks of the same nature, at the same time as excavating in cement.
During the last years, a great variety of models of this type of machinery has been manufactured. Among the most relevant of this year 2020 we can point out those that are listed below:
KOMATSU - 510
This KOMATSU-510 excavator is one of the most outstanding among those that have been manufactured this year, since it incorporates an isochronous motor, which will mean great savings in terms of fuel and energy.
Another interesting point that can be highlighted in this model is its fan, which can be controlled by the clutch, which gives the excavator greater safety and makes it more efficient.
KOMATSU - BR100R-1
Created By KOMATSU-BR100R-1 it consists of four models, which have an approximate weight of 25 to 40 tons. These models were presented at the last Intermat 2020 Fair, achieving great acceptance, especially due to the engines that KOMATSU has incorporated into these machines, which are Tier 4 Final.
This range of excavators continues to enjoy the reliability that until now has characterized all the constructions of this type of machinery.
On the other hand, great technology has been incorporated into this excavator model, with which fuel consumption will be visibly reduced.
Another of the highlights is the one that refers to the comfort that the operator will have when working, and that he will notice a lot in each of the operations that he carries out since he will have a pressurized cabin protected from noise and vibrations.
KOMATSU - D50A-15
It is an excavator manufactured by KOMATSU –D50A-15 and also presented at the Intermat 2020 fair.
It is a wheeled excavator, whose approximate weight is 17 tons, with a large number of features, such as offering great comfort and exceptional functions. The reduction of consumption is another of the properties that have been incorporated into this machinery.
KOMATSU D50-15
New KOMATSU D50-15, the most recent hydraulic excavator to hit the market in 2018, after being presented, and has pushed its sister D31PLL-20E out of the rankings, to number 5 in the “top five” of “ burrowing monsters ”, since it ranked 4.
With an operating weight of 676 to 686 tons with front loader and 684 to 694 tons with the rear, the PC7000-6 has a cab height of 9 m, a chassis length and width of 10.5 m and 9.6 m, respectively, as well as a bucket volume, both front and back, of 36 m³. The breakout and digging forces are 1741 kN and 1513 kN, respectively. The PC7000-6 features two 16-cylinder Komatsu diesel engines with a total output of 2,500 kW (2,352 hp) at 1,800 rpm. It has the famous Komtrax Plus monitoring system.
KOMATSU D31PLL-20E
KOMATSU-D31PLL-20E has an operating weight of up to 710 tonnes, making it the fifth-largest excavator in the world. Available with a backhoe and front bucket accessories, it has a track length and width of 10.51 m and 8.15 m, respectively, with a bucket volume of 42 m³. The arm advance force and the bucket digging force are 1765 kN and 1961 kN, respectively, with a maximum bucket, reach at the ground level of 19.37 m and a maximum digging depth of 8.4 meters.
The Komatsu PC8000-6 series models incorporate two 16-cylinder and Komatsu D31PLL-20E diesel engines, with a power that reaches 4020 hp at 1800 rpm.
