he service life of LPG forklifts is affected by many factors. It is usually measured by working hours or years of use, generally ranging from 8 to 15 years. The specific differences mainly depend on the following key factors:

I. Core Influencing Factors

• Intensity and frequency of use
  • If the forklift operates continuously under high intensity every day (such as more than 10 hours), the core components like the engine and hydraulic system will wear out faster, and its service life may be shortened to 8 - 10 years.
  • For intermittent low - intensity operations (such as 4 - 6 hours a day), the wear of components is slower, and the service life can be extended to 12 - 15 years.
• Quality of maintenance
  • Regular maintenance in accordance with specifications (such as changing engine oil, cleaning air filters, inspecting gas cylinder pipelines, maintaining hydraulic systems, etc.) can effectively reduce failures and extend the service life.
  • Lack of maintenance (such as not changing oil for a long time, ignoring the hidden danger of gas cylinder leakage) may lead to premature damage of the engine, reducing its service life by 30% - 50%.
• Working environment
  • When used in dry and clean indoor environments (such as food warehouses), the components are less likely to rust and be polluted, so the service life is longer.
  • Outdoor humid, dusty or corrosive environments (such as ports, chemical workshops) will accelerate the rusting of metal parts and the aging of circuits, which may reduce the service life by 20% - 30%.

II. Key Indicators for Judging Service Life

• Engine operating hours: Generally, the design limit of an engine is 10,000 - 20,000 hours. Beyond this, the failure rate will increase significantly.
• Condition of core components: If core components such as the engine, gearbox and hydraulic pump are severely worn (such as oil burning, power reduction, oil leakage), and the maintenance cost exceeds the residual value of the forklift, it is usually considered to have reached the end of its service life.

III. Suggestions for Extending Service Life

• Carry out regular maintenance in strict accordance with the manual, focusing on the engine, hydraulic system and fuel pipelines.
• Avoid overloading operations (the rated load of a forklift is usually 1 - 10 tons; overloading will seriously damage the frame and hydraulic system).
• Keep the working environment clean, and regularly clean the dust and oil stains on the surface and inside of the forklift.
• Operators should receive professional training to avoid improper operations such as sudden acceleration and sudden braking.
