What hydraulic oil is used for truck mounted cranes? Comprehensive analysis of hydraulic oil selection and hot topics
Recently, among the top ten hot topics discussed on the Internet, construction machinery maintenance and environmental protection occupy a prominent position. This article will combine the hot topics of the past 10 days to systematically answer the problem of hydraulic oil selection for truck-mounted cranes, and attach a structured data comparison table.
1. The correlation between hot topics and hydraulic oil selection
According to public opinion monitoring data, the following hot events directly affect the hydraulic oil market:
| Hot search keywords | Relevance | Influence dimension |
|---|---|---|
| New national standard for construction machinery | 89% | Increased requirements for environmental protection indicators |
| extreme weather operations | 76% | Temperature adaptability requirements |
| Hydraulic system failure | 92% | Oil quality concern |
2. Core parameters of truck-mounted crane hydraulic oil
Comparison of key indicators of mainstream brands of hydraulic oil:
| Oil type | Viscosity grade | Applicable temperature(℃) | Oil change interval (hours) |
|---|---|---|---|
| HM anti-wear hydraulic oil | 46# | -15~60 | 2000 |
| HV low temperature hydraulic oil | 32# | -30~40 | 1500 |
| HS ultra-low temperature hydraulic oil | twenty two# | -40~50 | 1800 |
3. Hydraulic oil selection guide
1.climate matching principle: It is recommended to use the HS series in the Northeast region, and the HM series in the South.
2.Device age factor: Equipment that has been used for more than 5 years should increase the viscosity grade, such as from 46# to 68#.
3.Economic considerations: According to the latest data from an e-commerce platform, the price difference between different brands reaches 40%:
| brand | 18L package price (yuan) | cost performance index |
|---|---|---|
| Shell | 1580 | 8.7 |
| Great Wall | 1260 | 9.2 |
| Kunlun | 1120 | 8.9 |
4. Hotspot Extension: Impact of New Environmental Protection Regulations
The recently released "Emission Standards for Non-Road Mobile Machinery" requires:
• Hydraulic oil containing zinc additives will be completely banned from 2024
• Biodegradation rate needs to be above 80%
• It is recommended to use oils certified by ISO 11158
5. Maintenance suggestions
1. Check the moisture content every 250 hours (standard value ≤ 0.1%)
2. Do not mix different brands of oil.
3. Avoid direct sunlight when storing. The shelf life is usually 36 months.
Combined with the current hot trend of "green operation and maintenance" in the construction machinery industry, it is recommended to give priority to hydraulic oil products that meet the latest environmental standards. This is not only a need for equipment maintenance, but also a reflection of corporate social responsibility.
