What is the excavator stopping surface?
In the field of construction machinery, the excavator's stopping surface is a key concept that directly affects construction safety and efficiency. This article will combine the hot topics and hot content of the entire network in the past 10 days to provide a structured analysis of the definition, function, technical parameters and industry trends of the excavator's stopping surface to help readers fully understand this professional terminology.
1. Definition and function of stopping surface
The parking surface refers to the support plane where the tracks or tires are in contact with the ground when the excavator is operating. Its flatness and stability directly affect the safety of equipment operation. According to industry standards, the parking surface must meet the following conditions:
| Technical indicators | Standard requirements |
|---|---|
| slope limit | Longitudinal ≤5°, transverse ≤3° |
| load bearing capacity | ≥1.5 times the weight of the entire machine |
| Ground type | Compacted earth/concrete/steel plate |
2. Analysis of recent industry hot spots
In the past 10 days, discussions about stopping surfaces in the construction machinery field have mainly focused on the following aspects:
| hot topics | Linked data |
|---|---|
| Smart leveling technology | The installation rate of new models in 2023 will increase by 42% |
| Accident statistical analysis | 63% of rollover accidents are related to improper parking surfaces |
| New material applications | The cost of using composite steel plates is reduced by 28% |
3. Comparison of key technical parameters
Mainstream brands have different technical requirements for the parking surface. The following is a comparison of the three models that have attracted the most attention in the market recently:
| model | Allowed slope | Minimum working area | special request |
|---|---|---|---|
| CAT 320 | 7° vertically/5° horizontally | 6.5×6.5m | Need to harden the ground |
| Volvo EC220 | 5° vertically/3° horizontally | 7×7m | Soft soil operations allowed |
| SANY SY215 | 6° vertically/4° horizontally | 6×6m | Standard anti-subsidence board |
4. Key points of construction specifications
According to the latest "Safety Code for Construction Machinery Construction" (GB/T 2023), special attention needs to be paid to the handling of the parking surface:
1. Professional instruments must be used for slope detection, and the error of manual visual inspection shall not exceed 0.5°.
2. Drainage ditches need to be installed during rainy season construction to prevent water accumulation from softening the foundation.
3. When parked for a long time, the ground subsidence should be checked every 72 hours.
5. Future technology development trends
Based on recent industry exhibitions and technical white papers, stopping surface technology will develop in three directions:
| Technical direction | Representative enterprise | Estimated time to commercialization |
|---|---|---|
| Automatic leveling system | Komatsu/Xugong | 2024Q2 |
| Beidou positioning monitoring | Zoomlion | 2023Q4 |
| Biodegradable backing board | Sany Group | 2025 |
Conclusion
As a basic but critical technical element, the standardized management of excavator parking surfaces is receiving unprecedented attention from the industry. With the popularization of intelligent monitoring technology and the application of new materials, the level of construction safety will be significantly improved in the future. It is recommended that operators regularly participate in the latest standards training to keep abreast of technological developments.
