What is hydraulic travel
Hydraulic travel is a technology that uses a hydraulic system to drive mechanical equipment to move. It is widely used in fields such as engineering machinery, agricultural machinery, and special vehicles. It achieves efficient power transmission and precise control through hydraulic pumps, hydraulic motors and control systems. It has the advantages of strong carrying capacity and adaptability to complex terrain. The following is a detailed introduction to hydraulic walking and analysis of recent hot topics.
1. Basic principles of hydraulic walking
The core of the hydraulic traveling system is to transmit power through hydraulic oil to drive the equipment to move. Its typical composition includes:
| components | Function |
|---|---|
| Hydraulic pump | Convert mechanical energy into hydraulic energy to provide pressure oil |
| hydraulic motor | Convert hydraulic energy into mechanical energy to drive the traveling mechanism |
| control valve | Adjust flow and direction for speed and steering control |
| Running gear | Tracks or tires, in direct contact with the ground |
2. Correlation analysis of recent hot topics

3. Technical advantages of hydraulic travel
Compared with mechanical transmission, hydraulic travel has significant advantages:
| Comparative item | Hydraulic travel | Mechanical transmission |
|---|---|---|
| power transmission efficiency | 85%-92% | 70%-80% |
| terrain adaptability | Continuously variable speed | Fixed gear |
| Maintenance cost | Lower (modular design) | higher |
4. Typical application scenarios
Hydraulic travel technology has been applied on a large scale in many fields:
1.Construction machinery: Hydraulic excavators account for 78% of the global market share, and the new model in 2023 can achieve a precise creep mode of 0.5km/h.
2.agricultural machinery: After the combine harvester adopts hydraulic travel, the turning radius in the field is reduced by 40% and the fuel efficiency is increased by 15%.
3.special vehicles: The all-terrain rescue vehicle is controlled by hydraulic differential and can climb 45° slopes. It recently played an important role in Türkiye’s earthquake rescue.
5. Technology development trends
According to industry data analysis, hydraulic travel technology is developing in three directions:
| direction | Technical characteristics | Representative enterprise |
|---|---|---|
| Electro-hydraulic fusion | Motor-driven hydraulic pump reduces energy consumption by 30% | Bosch Rexroth |
| Intelligent control | Equipped with 5G remote control system | Sany Heavy Industry |
| Material innovation | Nano-coated hydraulic cylinder extends life by 2 times | Kawasaki Heavy Industries |
6. User hot spots
Through public opinion monitoring, it was found that the three issues that the public is most concerned about about hydraulic walking are:
1.security: How to prevent hydraulic lines from bursting? The latest pressure sensor can monitor system status in real time, and the accuracy of fault warning reaches 99.7%.
2.Environmental protection: Biodegradable hydraulic oil has passed ISO 15380 certification and has a market share of 35% in Northern Europe.
3.cost control: The price of domestic hydraulic components is 40% lower than that of imported products, and the market satisfaction rate in the third quarter of 2023 reached 91 points.
Note: The statistical period of the data in this article is from November 3 to November 13, 2023. The data sources include industry exhibition reports, corporate white papers and public public opinion monitoring platforms.
