What is the development history of excavators?

Originally manual, the excavator has been more than 130 years since its invention in 2013, during which it has experienced a gradual development process from steam-driven bucket rotary excavators to electric-driven and internal combustion engine-driven rotary excavators, and fully automatic hydraulic excavators applying mechatronic and hydraulic integration technology. The first hydraulic excavator was invented by the Poclain factory in France. Due to the application of hydraulic technology, in the 40s of the 20th century, there was a hydraulic backhoe ground suspended excavator equipped with a tractor.

In 1951, the first fully hydraulic backhoe excavator was launched by the Poclain plant in France, which opened up a new space in the field of excavator technology development, and in the early and mid-50s of the 20th century, towed full-rotary hydraulic excavators and crawler full-hydraulic excavators were developed successively. The initial trial production of the hydraulic excavator is the use of aircraft and machine tool hydraulic technology, lack of hydraulic components suitable for various working conditions of the excavator, the manufacturing quality is not stable enough, the accessories are not complete. Since the 60s of the 20th century, hydraulic excavators have entered the stage of promotion and vigorous development, and the number of excavator manufacturers and varieties in various countries has increased rapidly, and the output has soared.

Between 1968 and 1970, the output of hydraulic excavators accounted for 83% of the total output of excavators, which was close to 100%.

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. First world war.

rear, diesel engine.

Also used in excavators, this diesel engine (or electric motor) driven mechanical excavator is the first generation of excavators.

The second generation of excavators: with the wide use of hydraulic technology, the excavator has a more scientific and applicable transmission device, hydraulic transmission instead of mechanical transmission is a big leap in excavator technology. In 1950, the first hydraulic excavator in Germany was born.

Mechanical drive hydraulicization is the second generation of excavators.

The third generation of excavators: electronic technology, especially computer technology.

The wide application of the excavator has an automatic control system, and also makes the excavator develop in the direction of high performance, automation and intelligence. The germination of mechatronics took place around 1965, and mechatronics technology was used in mass production hydraulic excavators.

Around 1985, the main purpose was to save energy. The electrification of excavators is the hallmark of the third generation of excavators.

Excavator industry manufacturers can be roughly divided into four categories. More than 7 percent of domestic excavators are occupied by foreign brands, domestic brands are still small digging and digging in the main, but the share of domestic excavators is gradually increasing, 2012 year-on-year increase.

In recent years, China has continued to expand the fields of infrastructure construction and transportation to meet the needs of China's rapid economic development. As an important construction machinery for excavating soil and sediment, excavators play a pivotal role in the entire engineering construction process, so the expansion of infrastructure, transportation and road construction projects in the future will promote the development of the excavator industry.

Major listed companies in the excavator industry:At present, the main listed companies in the domestic excavator industry are Sany Heavy Industry (Zoomlion), XCMG Machinery (Liugong Machinery, etc.).

Excavator sales, China's PPP infrastructure project investment.

1. Excavator sales rebounded

According to the data of the Construction Machinery Industry Association, the 25 host manufacturing enterprises included in the statistics in 2020 sold a total of 10,000 units of various excavation machinery products, a year-on-year increase compared with 2019. Among them, the sales volume in the domestic market increased year-on-year compared with 2019. export sales volume, a year-on-year increase compared with 2019.

In terms of product market structure, in December 2020, 3,517 large excavators were sold, a year-on-year increase over 2019; sales of medium-sized excavators were 7,451 units, a year-on-year increase; 16,351 small excavators were sold, a year-on-year increase of 42% over 2019.

2. Excavators are widely used

In China, most of the construction projects need to dig out the earthwork first. For example, in the process of infrastructure construction, it is necessary to dig out the earth, install natural gas and other pipelines and then landfill them, and in this process, Sun Yinzhong needs to use excavators to complete the excavation and landfilling. Similarly, in the process of real estate construction and highway construction, it is also necessary to dig out the earthwork and lay a solid foundation to ensure the quality of the project.

On the whole, excavators are almost necessary construction machinery in the fields of infrastructure, transportation and road construction, real estate, mining and mining, and have a wide range of use.

3. Infrastructure projects promote the growth of demand for excavators

At present, China is in a period of rapid economic development, and the demand for infrastructure, transportation, real estate and other projects is increasing, so in the future, China needs to increase efforts to carry out engineering construction to meet the increasing population. In the process of infrastructure construction and road construction, a large number of excavators are needed to carry out engineering operations, so in the future, with the increase of municipal engineering and road construction projects in China, the demand for engineering excavators in China will also increase.

-- China has a large number of infrastructure projects

In the future, China will continue to increase transportation infrastructure. In the "National Comprehensive Three-Dimensional Transportation Network Planning Outline", it is mentioned that by 2035, a modern and high-quality comprehensive three-dimensional transportation network will be built and 123 travel traffic circles will be realized across the country. In the work report of the two sessions, a targeted plan was also made for the transportation infrastructure construction project in 2021.

——Excavator sales may continue to increase in the future

4. The development of the excavator industry is showing a trend of intelligence and energy saving

With the development of modern technologies such as 5G, in the future, China's mining opportunities will develop towards the trend of intelligence and electronics, and autonomous driving and remote operation will become possible; At the same time, in the future, excavators will comply with China's environmental protection policies and develop towards a more fuel-saving and environmentally friendly trend.

Since the end of the sixties of the last century, China began to develop and develop excavator products, after just more than 40 years, especially in the reform and opening up of more than 30 years, China's excavator manufacturing industry has developed particularly rapidly.

Data show that in 2010, there were 252 enterprises above designated size in China's excavator manufacturing industry, achieving sales of 100 million yuan, product sales profit of 100 million yuan, and a total profit of 100 million yuan, a year-on-year increase of more than 80%.

According to the "Prospect of China's Excavator Manufacturing Industry Production and Marketing Demand and Investment Analysis Report" released by the Prospective Industry Research Institute, China's excavator market has increased by an average of 30% in the past ten years and has become one of the largest markets in the world. Judging from the current situation, China is in the peak period of infrastructure construction in road traffic, energy and water conservancy, urban construction and other aspects, the market demand for excavators is increasing year by year, and the actual cumulative sales of excavators in the country in 2010 exceeded 10,000 units, a year-on-year increase.

On the whole, the domestic ownership of the excavator is low, but the product is high, the sales model is mainly financial leasing or bank mortgage, once the credit has a code to accompany the relaxation, excavator sales will be the best product.

Although affected by the economic crisis, the growth rate has declined, but with the recovery of China's economy, China's excavator market capacity is still very large, there is still a lot of growth, and the growth rate in the next few years will also remain at 15%.

Excavator training: China's excavator industry has broad prospects.

In recent years, the actual sales volume of excavators in China has repeatedly broken people's expectations of the market in advance, and it is obvious that this excessively high growth rate is not conducive to the stable and healthy development of the market. China's territory is vast, the task of economic construction is very heavy, and the market demand for excavators is very large. Industry insiders believe that according to China's land, population, economic conditions, the average annual growth rate of excavators in 15 20 is a relatively normal development rate.

Excavator training: The report of the 16th National Congress of the Communist Party of China clearly put forward the goal of quadrupling the gross national product (GDP) and building a well-off society in an all-round way through the construction of the next 20 years. The growth target set from 2002 to 2020 is to quadruple GDP, which means that the average annual GDP growth rate must not be lower, which is a goal that must be achieved.
