Introduction of excavators

According to the different sizes, excavators can be divided into large excavators, medium excavators and small excavators; According to the different ways of walking, excavators can be divided into crawler excavators and wheeled excavators.

According to the different transmission methods, excavators can be divided into hydraulic excavators and mechanical excavators, and mechanical excavators are mainly used in some large mines. According to the use, excavators can be divided into different categories such as general excavators, mining excavators, marine excavators, and special excavators.

Large excavator models include Carter 320 is 20 tons, Carter 325 is 25 tons, Carter 330 is 30 tons, Komatsu 210 is 21 tons, and Komatsu 220 is 22.

Large excavator models include JH708 crawler excavator, 85 crawler mini excavator, and 1209 crawler excavator. 65 wheeled excavator, 70 wheeled dual-drive mini excavator, 85 wheeled dual-drive mini excavator, JHL60180 degree slewing excavator.

Type 110 180 slewing excavator. Each of the 18 roulette digging buckets can scoop up cubic meters of ore or dirt material, and this giant monster can create a pit the size of five football fields and 17 meters deep every day.

Large excavators

HCM, Hitachi Construction Machinery Co., Ltd., has developed the world's largest hydraulic excavator, model EX8000, with a working mass of 780 tons and a bucket capacity of 40 cubic meters. The assembly of the EX8000 hydraulic excavator has been completed. The mass-to-bucket ratio of large-scale excavation refers to the ratio of the mass of the excavator to the bucket capacity.

This value shows the efficiency and workmanship of the excavator.

In general, the lower this value, the more efficient the excavator is. At the same quality, the lower the value, the better. On the contrary, the higher this value, the more ineffective quality of the excavator is, and the worse the efficiency.

The large excavator model is:

1.Terex RH400

The Terex RH400 excavator, the largest excavator in the world, had 6 units in the world at that time, the first was manufactured in 1997, and the improved sixth RH400 was launched in 2002, of which the 5th was electrically driven, and the diesel version used two Cummins QSK60-C diesel engines (16 cylinders, turbocharged) with a fuel tank capacity of 16000L, 5 of these 6 were used in mines in the United States and 1 in Canada.

2.Liebherr R9800

Liebherr R9800 crawler excavator, is currently the world's second largest hydraulic excavator, can be described as "a shovel, 10,000 shovels", its weight of 804 tons, equipped with 2 Cummins QSK60 diesel engine, the total power of 4060 horsepower, fuel tank capacity of nearly 20,000 liters, bucket capacity of 42 cubic meters, can be configured with a front shovel or backhoe, when configured with a shovel, the maximum digging force can reach 2980kN, the maximum crushing force can reach 2350kN.

3.Hitachi EX8000

Hitachi EX8000 excavator, the first was successfully developed in March 2004, its control room is 10 meters from the ground, and the back is designed to be equipped with a practical space for items such as a dining table, microwave oven and refrigerator, which can still get a comfortable living environment in the 24-hour mine, considering the long-term continuous driving, using a flexible and lightweight electric joystick, equipped with two S16R-Y1TAA2 diesel engines, and a fuel tank capacity of 14400L.

4.Demag H740

The Demag H740 excavator, the largest Demag excavator, is designed and built for oil sands mining, the H740 is equipped with two Cat 3516B diesel engines and has a maximum digging force of an astonishing 2320kn.

5.Komatsu PC8000

PC8000 excavator, is the top model of Komatsu excavator, there are two forms of diesel engine drive and electric drive, using two Komatsu SDA16V160 (16-cylinder turbocharged) diesel engine or 6600V high voltage (motor power 2900KW) as power, fuel tank capacity 14000L.

Model & Bucket Capacity:

1. The model is 35, and it is stuffy, and the tonnage bucket capacity is about cubic meters.

2. The model is 60, that is, the bucket capacity of 6 tons is about cubic meters.

3. The model is 120, that is, the bucket capacity of 12 tons is about cubic meters.

4. The model is 160, that is, the bucket capacity of 16 tons is about cubic meters.

PC200-8, PC is the generation that represents the Komatsu excavator series, 200 is the representative of the 20-ton class, and -8 represents the generation of innovation.

Carter 306, 3 is on behalf of Carter excavator series 06 is on behalf of 6 tons, and the new algebra is represented by ABCD.

Excavators usually say 60, 85, 200, 220, 250, 300 This number represents the model and bucket capacity.

For example, if the model is 200, the capacity of the 20-ton bucket is about cubic meters.

The model is 220, which means that the bucket capacity of 22 tons is about cubic meters.

The model is 240, that is, the bucket capacity of 24 tons is about cubic meters.

The first generation of excavators: the emergence of electric motors and internal combustion engines has made excavators have advanced and suitable electric devices, so various excavator products have been born. In 1899, the first electric excavator appeared.

After the First World War, diesel engines were also used in excavators, and this type of mechanical excavator driven by a diesel engine (or electric motor) was the first generation of excavators.
