What kind of hydraulic oil is used for small forklifts?

In the field of construction machinery, the hydraulic system of a small forklift is one of its core components, and the choice of hydraulic oil directly affects the performance and life of the equipment. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the selection standards, common types and precautions for small forklift hydraulic oil, and provide structured data reference.

1. The role of hydraulic oil in small forklifts

What kind of hydraulic oil is used for small forklifts?

Hydraulic oil is not only a medium for transmitting power, but also has functions such as lubrication, cooling and rust prevention. According to statistics, about 70% of hydraulic system failures are related to improper oil selection or maintenance.

FunctionDescriptionimportance
power transmissionPressure drives hydraulic cylinders and motorsCore functions
Lubrication protectionReduce wear on metal partsExtend life
Heat dissipation coolingAbsorbs heat generated by the systemprevent overheating
Sealed and rust-proofProtect components from corrosionMaintain tightness

2. Selection criteria for hydraulic oil for small forklifts

According to ISO international standards and recommendations from mainstream manufacturers, when choosing hydraulic oil, you need to focus on the following indicators:

parametersStandard rangeDetection method
Viscosity gradeISO VG32/46/68ASTM D445
pour point≤-15℃ (in cold areas, ≤-30℃ is required)ASTM D97
flash point≥200℃ASTM D92
Wear resistancePB value≥600NASTM D2783
cleanlinessNAS level 8 or belowISO 4406

3. Comparison of mainstream hydraulic oil types

The following is the data of the top five hydraulic oil products sold on e-commerce platforms in the past 10 days:

brandModelViscosity gradeApplicable temperaturePrice(yuan/18L)
ShellTellus S2MXISO VG46-20℃~60℃680
MobilDTE 10 ExcelISO VG68-10℃~80℃720
Great WallL-HM46ISO VG46-25℃~70℃550
KunlunTianrun HM46ISO VG46-30℃~65℃490
CastrolHyspin AWSISO VG32-40℃~50℃850

4. Precautions for use

1.Oil change interval: It is recommended to replace every 2000 hours or 1 year under normal operating conditions, and it should be shortened to 1000 hours under severe operating conditions.

2.Mixing taboos: It is forbidden to mix hydraulic oils of different brands/models, as sediment may occur.

3.Storage requirements: The shelf life of unopened oil is 3 years, and it needs to be stored away from light and moisture.

4.pollution control: The fuel tank needs to be cleaned before refueling. It is recommended to use a 10μm precision oil filter.

5. Industry hot trends

According to Baidu Index, the search volume of the keyword "hydraulic oil selection" has increased by 35% in the past 10 days, with the main focus being on:

hot topicsDiscussion popularityGeographical distribution
Low temperature starting performance28%Northeast/Northwest
Biodegradable hydraulic oil19%coastal areas
Hydraulic oil online monitoring15%Industrial dense area
Identification of counterfeit oil products22%Nationwide

Summary: ISO VG46 anti-wear hydraulic oil (HM grade) is recommended for small forklifts, and low-condensation hydraulic oil can be selected for operations in cold areas. Regular testing of oil viscosity, moisture content and contamination can effectively prevent system failures. With technological advancement, synthetic ester hydraulic oil and intelligent monitoring systems are becoming new trends in the industry.
