What Are the Reasons Why a Lift Truck Cannot Ascend?
2 Answers
The reasons why a lift truck cannot ascend are as follows: 1. Overload: Each lift truck has its own rated load capacity. Once overloaded, it may exhibit weak lifting or fail to ascend. The Shuangli hydraulic lift platform reminds users to appropriately reduce the load. 2. The return oil valve is not closed: Tighten the return oil valve. 3. The manual pump check valve is stuck: The return mechanism fails. Shuangli lifting machinery suggests unscrewing the oil pump valve port bolt, inspecting, cleaning, and replacing with clean hydraulic oil. 4. The gear pump is damaged: The discharged oil lacks pressure. Replace the gear pump. 5. Insufficient hydraulic oil: The Shuangli hydraulic lift platform can be refilled with sufficient hydraulic oil.
There are many reasons why a lift truck may not rise, and I think the most common issue is with the hydraulic system. The oil level might be too low or the oil quality may be dirty, causing the pump to fail in drawing oil, resulting in insufficient lifting force. Alternatively, valve blockage or oil pipe leakage can lead to a loss of pressure. Electrical failures are also possible, such as blown fuses, poor contact in control switches, or short circuits in the circuit, which can prevent the lifting command from reaching the pump. Improper operation can also cause problems, like overloading with excessively heavy items, triggering the safety mechanism to automatically lock, or uneven ground with improperly adjusted stabilizers. I've found that regular maintenance is crucial—changing the oil when necessary and cleaning the valves to avoid these troubles. If the problem persists, it's best to consult professional repair services rather than attempting DIY fixes that could lead to bigger hazards.
