What does the excavator rely on to move? Reveal the technical principles and industry hot spots behind them
In recent years, with the rapid development of infrastructure projects, excavators, as one of the core engineering machinery, have attracted much attention for their technical principles and performance. This article will combine the hot topics on the Internet in the past 10 days, deeply explore the walking principles of excavators, and present relevant technical points and industry trends through structured data.
1. The core principle of excavator walking
The walking function of the excavator mainly relies on the following key components and technologies:
| Component name | Function description |
|---|---|
| Track system | Distributes weight with rubber or metal tracks, providing stability and grip |
| Travel motor | Hydraulic or electric drive to control track rotation |
| Reducer | Reduce motor speed and increase torque |
| control valve | Adjust the flow direction of hydraulic oil to achieve forward, backward and steering |
2. Recent industry hot spots and data
According to search data from the entire Internet, excavator-related topics in the past 10 days have mainly focused on the following areas:
| hot topics | Discuss the popularity index | main focus |
|---|---|---|
| Electric excavator technology | 85 | Environmental protection, battery life, charging efficiency |
| Intelligent control system | 78 | Automation, remote control |
| Domestic substitution trend | 72 | Independent research and development of core components |
| Second-hand excavator market | 65 | Price fluctuations, quality assessment |
3. Analysis of technology development trends
1.Electric transformation accelerates: With the advancement of global carbon emission reduction policies, electric excavators have become the research and development focus of mainstream manufacturers. For example, the SY16E electric mini excavator recently launched by Sany Heavy Industry has a battery life of up to 8 hours.
2.Intelligent upgrade: Realize remote monitoring and automatic operation of excavators through 5G and IoT technology. Komatsu's smart excavator has been piloted in American mines.
3.Breakthrough in localization: Hydraulic motors, control valves and other core components have long relied on imports, but companies such as Xugong Group have begun mass production of high-pressure hydraulic components of their own brands.
4. User FAQs
Q: Why do some excavators use rubber tracks and some use metal tracks?
A: Rubber tracks are suitable for hardened roads to reduce damage to the ground; metal tracks are more suitable for rugged terrain and have stronger wear resistance.
Q: What are the common causes of walking motor failures?
A: Hydraulic oil contamination, seal aging or overload operation are the main reasons and require regular maintenance.
5. Summary
The excavator's traveling system is a comprehensive reflection of mechanical, hydraulic and electronic control technologies, and its development closely follows the industry's trend of intelligence and electrification. In the future, with technological advancement and the evolution of market demand, excavators will usher in a new era that is more efficient and more environmentally friendly.
