How Do You Fix a Pallet Jack That Won't Lift?

Pallet jacks are a crucial piece of equipment in any warehouse. They are essential for moving heavy loads around and ensuring that they are transported safely. However, just like any other machinery, pallet jacks can sometimes break down, causing unnecessary delays and frustration. One of the most common problems that pallet jacks face is the inability to lift. When a pallet jack won't lift, it is critical to identify the cause of the issue and learn how to fix it quickly. In this article, we will give you a step-by-step guide on how to fix a pallet jack that won't lift.

1. Check Hydraulic Fluid Level

The first thing you must check when your pallet jack won't lift is the hydraulic fluid level. Hydraulic fluid is what powers the lifting mechanism of the pallet jack, and if the level is too low, it will not be able to lift anything at all. To check the hydraulic fluid level, locate the hydraulic fluid reservoir on your pallet jack. It is usually located at the rear of the jack or on the lift frame.

Once you have located the hydraulic fluid reservoir, check the fluid level and make sure it is within the recommended range. If the fluid level is low, top up the reservoir with the recommended hydraulic fluid immediately. Remember that if you are unsure what type of hydraulic fluid to use, refer to the manufacturer's manual for guidance.

2. Inspect the Pump

Another possible reason why your pallet jack won't lift is that the pump may be damaged or faulty. The pump is responsible for pressurizing the hydraulic fluid, which, in turn, powers the lifting mechanism. If the pump isn't working correctly, the pallet jack will not be able to lift.

To inspect the pump, locate it on your pallet jack. It is usually located within the hydraulic fluid reservoir. Once you have located the pump, check to see if there are any loose connections or damage to the pump itself. If you notice any damage, you may need to replace the pump with a new one.

3. Check the Lift Cylinder

If your pallet jack won't lift, it is possible that the lift cylinder may be damaged or worn out. The lift cylinder is the component of the pallet jack that powers the lifting mechanism. Over time, the cylinder's seals and pistons can become worn out, preventing the cylinder from functioning correctly.

To check the lift cylinder, locate it on your pallet jack. It is usually located beneath the forks or the lift frame. Once you have located the lift cylinder, inspect it to see if there are any visible signs of damage or wear. If you notice any damage, you may need to replace the lift cylinder with a new one.

4. Inspect the Lift Chains

Another possible cause of a pallet jack that won't lift is damaged or loose lift chains. The lift chains are responsible for lifting the load and can sometimes become damaged due to wear and tear.

To inspect the lift chains, lift the pallet jack into the air, and look for any visible signs of damage or loose chains as you do this. If you notice any damage or loose chains, you will need to replace them with new ones.

5. Check the Pressure Relief Valve

The pressure relief valve regulates the pressure in the hydraulic system of the pallet jack. If the valve is not working adequately, it may prevent the pallet jack from lifting. To check the pressure relief valve, locate it on your pallet jack. It is usually situated near the hydraulic fluid reservoir.

Once you have located the pressure relief valve, inspect it to see if there are any visible signs of damage or wear. If you notice any damage, you may need to replace the valve with a new one.

Final Thoughts

In summary, pallet jacks are essential pieces of equipment in any warehouse. However, they can sometimes break down, causing unnecessary delays and frustration. If your pallet jack won't lift, it is critical to identify the cause of the issue promptly, to avoid any further delays. We hope the guidelines we have outlined above will help you fix your pallet jack quickly and get back to work. Remember that if you are unsure about any of the steps, consult the manufacturer's manual or seek the help of a professional mechanic. Good luck!
