When was the excavator invented? Unveiling the milestones of engineering machinery

As the core equipment of modern engineering construction, the excavator has attracted much attention. This article will combine the popular topics and hot topics on the Internet for the past 10 days, present the invention time, key figures and technological evolution of the excavator in the form of structured data, and attach a compilation of related hot events.

1. Time and background of the invention of the excavator

The prototype of the excavator can be traced back to the early 19th century, but the birth of modern hydraulic excavators was an important breakthrough in the 20th century. The following are the key time nodes:

2. Hot events in engineering machinery on the entire network in the past 10 days

Based on recent hot search data, the following topics are related to excavator technology or industry trends:

3. Technology evolution and future trends

From steam power to intelligence, excavator technology has undergone many innovations:

• Power system: Steam → Diesel → Electric → Hydrogen Energy
• Control method: Mechanical lever → hydraulic control → remote remote control → automatic driving
• Application scenarios:Mine/Infrastructure →Disaster Relief/Space Exploration

According to industry forecasts, the global smart excavator market size will exceed US$50 billion by 2030, with China, Japan and Germany as the main technology exporters.

4. Why is the invention of an excavator so important?

The emergence of excavators has completely changed the way human engineering construction:

1. Improved efficiency: manual excavation takes 100 days, modern excavators only take 1 day
2. Enhanced safety: Replacement of high-risk jobs
3. Economic Value: The annual scale of the global engineering machinery market exceeds US$200 billion

In the future, with the integration of AI and new energy technologies, excavators will continue to push the boundaries of human infrastructure capabilities.
