In this blog post, we'll delve into the common problems that arise with electric pallet jacks and provide clear, actionable solutions to keep your operations running smoothly.
Troubleshooting Common Problems with Electric Pallet Jacks
The following video briefly describes the most common issues with electric pallet jacks and their troubleshooting steps.
1. No Power
When electric pallet jacks fail to power on, it's often attributed to battery-related issues. Understanding the root causes behind this frustrating problem is key to effective troubleshooting.
Here are some things you can check if your electric pallet jack has no power:
Battery won't hold a charge:
Rapid battery drainage or shortened lifespan in your electric pallet jack may result from various factors such as aging, overcharging, or deep discharging.
To mitigate these issues, adhere strictly to the manufacturer's charging and battery maintenance guidelines. Also, refrain from unplugging your pallet jack for extended durations, potentially harming the battery.
Battery isn't charging:
If your electric pallet jack's battery fails to charge, it might be due to a faulty charger, a loose connection, or a blown fuse.
Start by examining the charger for signs of malfunction, ensuring it's securely plugged in and operational. Test its functionality with another device or a multimeter to verify voltage output. Next, scrutinize the connection between the charger and the battery, rectifying any loose wires or corrosion present.
Additionally, inspect the battery fuse for signs of damage; if blown, promptly replace it with a new fuse of identical rating to restore functionality.
Battery leaks:
If your battery leaks acid or water, it might be due to overcharging, overheating, or physical damage. This can be very dangerous and harmful for your electric pallet jack and yourself, so you should handle it cautiously and wear protective gloves and eyewear. Dispose of the leaking battery properly as per the local regulations.
However, to prevent this issue in the future, always use a compatible charger and avoid exposing your battery to extreme temperatures or impacts.
2. Pallet Jack Won't move
Another common problem with electric pallet jacks is when they won't move or have reduced speed or power. This can happen for several reasons, but the most common ones are related to the motor, the brakes, or the wheels.
Here are some things you can check if your electric pallet jack won't move:
Motor:
If your motor doesn't work or makes strange noises, it might be due to a faulty switch, a bad connection, or a worn-out part.
To fix this, you should first check the switch and ensure it's in the right position and not damaged. Check the wiring and connections between the motor and the battery, and ensure there are no loose or broken wires.
Inspect the motor thoroughly and see if there are any signs of wear or damage on the brushes, bearings, or gears. If any parts are worn out or damaged, you should replace them with new ones.
Brakes:
If your brakes don't work or are stuck, it might be due to a faulty solenoid valve, a low fluid level, or a worn-out pad.
Check the solenoid valve and make sure it's working properly and not leaking. Also, inspect the brake pads and see if they're worn out or damaged.
Wheels:
If your wheels don't turn or are hard to steer, it might be due to a flat tire, a bent axle, or a dirty bearing.
Make sure the wheels are inflated properly and not punctured or damaged. You should also check the axles and ensure they're not bent or broken. Clean and lubricate the bearings and ensure they're not clogged or seized.
3. Lift Doesn't Work
If the electric pallet jack lifting mechanism doesn't work or has reduced height or capacity, this could be because of several reasons, such as:
- Low hydraulic fluid
- Faulty pump
- Damaged piston
- Worn out seals
- Loose, misaligned, or broken lift chain
- Bent, cracked, or overloaded forks
Inspect and diagnose each issue and consult with a professional technician to resolve them. If needed, replace any of the parts, such as worn-out seals, damaged pumps, etc., as soon as possible to avoid unnecessary downtime.
4. Electric Component Failure
Electric pallet jacks malfunction when one or more of their electric components fail. Here's how to deal with this issue.
Loose wires:
If your wires are loose, they may not be able to transmit the electric signals properly. To fix this problem, you may need to tighten the wires or replace them if they're broken.
Corroded terminals:
If your terminals are corroded, they may not be able to conduct the electric current properly. Clean the terminals or replace them if they're damaged.
Faulty switches:
If switches are faulty, they may not be able to turn on or off the electric functions of your pallet jack. Replace your switches or have them repaired by a professional.
Faulty sensors:
If your sensors don't work or give wrong readings, it might be due to a faulty sensor, a bad connection, or a dirty lens. To fix this, carefully check the sensor performance and make sure it's working properly and not damaged. Check the wiring and connections between the sensor and the controller, and ensure there are no loose or broken wires. Clean and calibrate the sensor and ensure it's not dirty or misaligned.
5. Unusual Noises
Another common problem with electric pallet jacks is when they make unusual noises that indicate something is wrong with them.
Strange noises often indicate mechanical issues. These noises can come from different parts of the electric pallet jack and have different causes and solutions. It could be anything from worn-out bearings to loose components. A thorough inspection is essential.
Here’s how you can diagnose them:
Lack of lubrication:
If your parts are not lubricated enough, they may create friction and noise. To fix this problem, lubricate your parts regularly or use a better-quality lubricant.
Misalignment:
If your parts are not aligned properly, they may rub against each other and create noise. In this case, you may need to adjust your parts or have them aligned by a professional.
Wear and tear:
If your parts are worn out or damaged, they may create noise and vibration. Once identified, replace your broken parts or have them repaired by a professional.
6. Error Codes
Electric pallet jack error codes are signals displayed on the control panel to alert you of specific problems that require the operator’s attention. These codes vary between manufacturers and models, commonly indicating issues like:
- Battery problems: low charge, charging faults, or leaks.
- Motor or controller malfunctions: affecting movement or lifting functions.
- Hydraulic system issues: low fluid levels, air in the system, or faulty components.
- Electrical component failures: loose wires, damaged switches, or overheating.
Refer to your user manual or manufacturer’s guide to decipher these codes and address the underlying issue. If you're unsure of the problem or unable to resolve it yourself, seek assistance from a trained technician.
