Poquelin EC1000-the pioneer of large-scale hydraulic excavator, weighing 140 tons, bucket capacity of 5 cubic meters, horsepower of 780hp, produced in 1970, which was the highest in the world at that time.

Marion-Dresser hydraulic model 3560 was built in 198 1 year, with a total weight of 272t, bucket capacity 17m3, horsepower 1400 horsepower, 198 1 year,/kloc.

1983 SMEC 4500, which was also the largest hydraulic model in the world at that time, weighed 420 tons, with a bucket capacity range of 15-30 cubic meters and a power of 2400hp/ 1800rpm. It may be a product jointly developed by several departments.

Liebherr R996, 1995, bucket capacity: 36m3, total equipment mass: 668t, power: 2240kW, Liebherr's flagship excavator, was the largest hydraulic excavator in the world at that time.

RH400, the largest hydraulic excavator in the world before 2008,/KLOC-0 was first introduced in 1997, with 870 tons; In 2002, the sixth platform appeared and its weight increased to 980 tons.

At present, the world's largest single bucket excavator;

On June 26th, 2008, 65438, China's first 55m3 excavator was shipped from Taiyuan Heavy Industry. The equipment is 22 meters high, which is equivalent to the height of an eight-story building. Its total weight is 1.400 tons, which is equivalent to the total weight of 70 railcars. Its bucket capacity is 56 cubic meters, that is to say, the monthly excavation amount can reach 654.38+00,000 cubic meters. It is not only the largest excavator in China, but also the largest excavator in the world, which can meet the mining conditions of all open-pit mines in the world today.

At present, the largest multi-bucket excavator in the world;

This excavator is 3 1 1 foot long, 705 feet long and weighs 45,000 tons. The manufacturing cost is $ 100000000. The design and manufacturing time is as long as five years, and it needs five people to operate! The diameter of the bucket wheel is over 70 feet. There are 20 barrels. Each barrel can hold more than 530 cubic feet (soil, etc.). A 6-foot-tall man can stand in a bucket. The excavator moves forward 12 wheels for driving (each wheel 12 feet wide, 8 feet high and 46 feet long). The top speed of the excavator is three hours and one mile (65,438+0/3 miles per hour), and it can clear more than 76,455 cubic meters of soil every day (65,438+000,000 trucks can transport 40 cubic yards every day).
