The mini electric forklift, also an Electric Pallet Truck, plays a very significant role in daily production operations. But how can we maintain it in order to extend its service life as much as possible?
Excellent question! Proper maintenance is crucial for the safety, performance, and longevity of a mini electric forklift (often called a walkie or power pallet truck). Here is a comprehensive guide to maintenance methods, broken down into daily, weekly, monthly, and periodic tasks.
This is the most critical routine for safety and preventing downtime.
Battery:
Battery is very important for the battery Electric Pallet Truck. Check charge level and plug in at the end of each shift (follow the manufacturer's charging routine).
Inspect cables and connectors for damage.
Ensure the battery is securely seated and the compartment is clean and dry.
Forks & Lower Assembly:
Visually inspect forks for cracks, bends, or excessive wear, especially at the heel.
Check for loose mounting bolts.
Controls:
Test all functions: horn, lights (if equipped), forward/reverse, lift/lower, brake, and emergency stop.
Ensure the control handle moves smoothly and returns to neutral.
Tires:
Check for wear, cuts, or embedded debris (polyurethane) or proper inflation (pneumatic).
General:
Look for any visible fluid leaks (hydraulic oil).
Wipe down the unit, keeping it free of dirt, debris, and moisture.
Thorough Cleaning:
Clean the battery compartment and terminals (use a baking soda/water solution for corrosion, then rinse and dry).
Remove dirt from the fork channels and lift chain/roller area.
Detailed Inspection:
Check hydraulic fluid levels (sight glass or dipstick).
Inspect all hydraulic lines and fittings for leaks, kinks, or wear.
Examine the drive motor area for accumulated debris.
Check that all safety labels are present and legible.
Mechanical Check:
Verify wheel condition and check for play in wheel bearings.
Inspect the lift chain tension and lubrication (if applicable).
Lubrication:
Lubricate all pivot points on the control handle and steer axle as per the manual.
Lubricate fork carriage rollers and lift chains (use the lubricant specified by the manufacturer, often a dry-film type).
Detailed Component Check:
Test the functionality of the braking system. Check brake adjustment on mechanical brakes.
Inspect electrical connections for tightness and corrosion.
Check and tighten frame and mast bolts to proper torque specifications.
Examine the condition of the contactor/controller area for dust or debris.
Performance Test:
Verify the forklift holds its rated capacity without drift (lift and hold test).
Check for any unusual noises during operation.
This often requires a trained technician.
Hydraulic System:
Change the hydraulic fluid and replace the filter (if equipped).
Thoroughly inspect the hydraulic pump and cylinders.
Drive Unit:
Inspect motor brushes (on brush-type motors) and commutator.
Check gearbox oil level in the drive unit (sealed units may not require service).
Electrical System:
Perform a battery discharge test to check battery health.
Conduct a diagnostic check on the controller for error codes and performance.
Check and calibrate sensors (e.g., load sensing).
Comprehensive Inspection:
Detailed inspection of all wiring harnesses for chafing or damage.
Full structural inspection of the mast, forks, and frame.
Watering (Flooded Lead-Acid Batteries ONLY):
Check water levels after a full charge, not when discharged. Use only distilled water.
Never let plates be exposed to air.
Charging:
Use the correct charger provided with the truck.
Avoid opportunity charging (plugging in for short periods). Allow the battery to complete a full charge cycle when possible.
Let the battery cool down (30+ minutes) before charging after heavy use.
Cleaning:
Keep the top of the battery clean and dry to prevent tracking (current running across dirt causing shorts).
Electronics:
Moisture and dust are the biggest enemies. Keep control panels and connectors clean and dry.
Compact Size:
They often operate in tighter spaces, so bumping into racks is more common. Daily fork and mast inspection is even more critical.
Walkie vs. Rider:
Walkies have more operator contact with the floor, increasing dirt/debris ingress. Pay extra attention to cleaning the drive tire and its motor area.
Keep a Logbook:
Record all daily checks, services, repairs, and battery watering. This helps track trends and is vital for warranty claims.
Follow the OEM Manual:
The manufacturer's maintenance schedule in the operator's manual is the ultimate authority. Use their recommended fluids, lubricants, and procedures.
Proactive Tip:
Train operators to report anything unusual immediately—strange sounds, reduced performance, or warning lights. Most major failures are preceded by small symptoms.
By following this structured maintenance program, you maximize the safety of operators, ensure consistent productivity, protect your investment, and avoid costly unplanned repairs. For major periodic services, consider using authorized technicians.
