Common Hydraulic System Failures in Forklifts and How to Handle ThemHere are some common failures in the hydraulic system of forklifts and the corresponding repair solutions: 1. Oil leakage: Oil leakage is a common issue in hydraulic systems. The causes can be a broken hose, poor sealing, or damaged components. To repair, identify the cause of the leakage and replace the damaged parts or repair the hose. 2. Loss of pressure: If the forklift does not have enough pressure to lift or hold loads, it may be due to a malfunctioning control valve or other issues in the system. Check and repair the control valve, inspect other components such as pumps, relief valves, and hoses to find the cause of pressure loss. 3. Inoperability: Forklifts may not operate due to various reasons, including a non-starting motor, malfunctioning control valve, or damaged components. Inspect and repair any faulty components, check power supply, and ensure all electrical connections are correct. 4. Unusual noise: If you hear strange noises from the hydraulic system, there may be issues with the pump, valve, or hoses. Inspect and repair any damaged or worn-out components and ensure all hoses are securely connected. 5. System instability: If the forklift cannot maintain its position or oscillates while lifting loads, it may be due to a malfunctioning relief valve or improperly adjusted pressure. Check and repair the relief valve, inspect pressure levels, and adjust if necessary. 6. Loss of lifting function: If the forklift cannot lift or lower loads properly, it may be due to a malfunctioning control valve or pump. Check and repair the control valve, inspect the pump and other components to determine the cause of loss of lifting function. 7. Slow response or unresponsiveness: If the forklift moves slowly or does not respond when controlled, it may be due to a stuck control valve or pump issues. Check and clean the control valve, inspect the pump and other components to resolve this issue. 8. Excessive pressure: If the pressure in the hydraulic system is too high, it can cause oil leakage or damage other components. Check and adjust the pressure in the system according to manufacturer’s instructions. 9. System vibration: If the forklift vibrates while moving or lifting loads, it may be due to worn-out or loose components. Inspect and repair any damaged components, ensuring all connections are tightened. 10. Instability during lifting: If the forklift cannot maintain its position or is unstable while lifting loads, it may be due to a malfunctioning relief valve or control valve. Check and repair the relief valve, inspect the control valve, and adjust if necessary. 11. Instability during movement: If the forklift is unstable or skids during movement, it may be due to steering system or wheel issues. Inspect and repair the steering system, check and adjust wheels to ensure safe and stable forklift movement. 12. Loss of control: If you cannot control or maneuver the forklift accurately, it may be due to a malfunctioning control system or steering component. Inspect and repair any faulty components, check and adjust the control system for optimal control ability. 13. Overheating: If the hydraulic system becomes excessively hot after a period of use, it may be due to insufficient oil flow or ineffective cooling. Check and clean oil filters, inspect and adjust oil flow to keep the hydraulic system working well without overheating. 14. Inconsistent operation: If one part of the hydraulic system operates inconsistently compared to others, it may be due to a malfunctioning control valve or damaged component. Check and repair the control valve, inspect and replace any faulty components to ensure consistency in system operation. 15. Inoperability after a period of use: If the forklift does not operate after a period of use, it may be due to worn-out components or the need for lubrication. Inspect and repair any damaged components, lubricate necessary parts to ensure the system always operates well after each use. 16. Inoperability after startup: If the forklift does not operate after startup, it may be due to weak batteries or electrical system issues. Check and recharge batteries, inspect and repair electrical components to ensure the system operates well after startup. 17. Unresponsiveness when lifting loads: If the forklift does not respond when attempting to lift a load, it may be due to a malfunctioning control valve or pump. Check and repair the control valve, inspect and replace the pump if necessary to ensure proper operation when lifting loads. 18. Inoperability after a collision: If the forklift experiences a strong collision and then does not operate, it may be due to damaged components or lost connections. Inspect and repair any damaged components, reestablish connections if necessary. By addressing these common hydraulic system failures in forklifts promptly and effectively, you can ensure smooth operations and maintain safety in your workplace.

Advice on Choosing Used Container ForkliftsDefinition of Used Container Forklifts Used container forklifts are specialized vehicles used for transporting and stacking containers. These forklifts have been previously used for a certain period of time before being resold on the market. Used container forklifts are typically 2-10 years old, have been operating reliably, and can continue to be effectively used for many more years. The Importance of Choosing the Right Type of Used Container Forklift Choosing the right type of used container forklift is crucial as it determines work efficiency, operating costs, and even safety for both the operator and the cargo and surrounding equipment. Key factors to consider include load capacity, size, container lifting speed, durability, reliability, maintenance costs, and availability of spare parts. Each type of forklift is suitable for specific tasks and operating environments. Therefore, businesses need careful guidance and selection when purchasing and using used container forklifts. I. Benefits of Choosing Used Container Forklifts 1. Cost savings compared to new vehicles The biggest advantage of used container forklifts is their significantly lower price compared to new vehicles, usually only 30-60% of the original value. This affordable price range is suitable for many small and medium-sized businesses. Purchasing used container forklifts helps businesses save considerable initial investment costs as well as operating expenses while still achieving profitability. 2. Environmental protection and recycling Using used container forklifts helps extend the lifespan of equipment, reduce industrial waste, and save resources and energy consumed in producing new vehicles. This approach promotes circular economy practices and environmental protection that many countries are adopting. 3. Work efficiency and stability of used forklifts After a period of use, container forklifts often reach a stable operational state with main components having passed their “childhood” stage, resulting in fewer breakdowns. Many models, when properly and regularly maintained, can be used continuously for 20 years or more without a decrease in performance. Furthermore, experience in operating and repairing familiar models is often higher compared to newly introduced forklifts. II. Important Factors to Consider When Choosing Used Container Forklifts When selecting used container forklifts, buyers need to carefully evaluate technical condition, structure, and operational history to ensure quality and reliability during use. 1. Check technical condition and maintenance – Engine and transmission system – Check cylinder compression pressure, oil/grease leaks – Starting capability, abnormal engine noise – Smoothness of power transmission system – Steering and braking system – Smooth steering, effective braking – No brake fluid leaks – Check tire condition and suspension system – Tires meet wear standards – Check shock absorber condition, lifting cylinder 2. Inspect structure and frame of the forklift – Check welding and frame durability: no deformation or cracks – Condition of other important components: gearbox, driver’s cabin… 3. Examine the usage history and maintenance records of the forklift – Operating hours – the lower the better – Complete maintenance records according to manufacturer’s requirements – Proper storage and operation conditions (non-harsh environments) III. Well-known and Reliable Brands Some reliable and well-known used container forklift brands on the market include: 1. Famous manufacturers: – Kalmar – Konecranes – Hyster – Linde – Toyota -Crown These are leading global brands in container forklifts with proven reliability and quality over time. 2. Highly rated used container forklift models: -Kalmar DRF 400-450: efficient electric plug-in empty container handler -Hyster H22XM: smooth-operating diesel container loader/unloader -Toyota 02-8FD: durable diesel forklift with stable power […]
