Daily Maintenance Checklist for Electric Pallet Stackers

Views: 0 Author: Site Editor Publish Time: 2026-10-10 Origin: Site

In the daily operation of an Electric Pallet Stacker, the quality of maintenance execution directly determines equipment availability and long-term maintenance costs. Taking Diding Lift's 2T Electric Walkie Pallet Stacker CDDA as an example, its 24V/82Ah maintenance-free gel battery, built-in charger design, 0.9kW AC drive motor, and 2.2kW AC lifting motor have already reduced maintenance complexity at the design level. Nevertheless, an executable daily maintenance checklist remains essential for long-term stable operation. This guide provides a ready-to-use checklist organized by daily, weekly, and monthly cycles.

1. Daily Pre-Shift Inspection Checklist

The daily pre-shift inspection is the first line of defense in the maintenance system, typically completed within 5-10 minutes. Operators should verify each item before starting the equipment.

1.1 Appearance and Structure Inspection

Check Item	Method	Pass Criteria
Body Appearance	Visual inspection	No visible deformation, cracks, or oil leaks
Forks	Visual inspection of arms and tips	No cracks, severe wear, or bending
Mast	Visual inspection of rails and chains	Chains properly tensioned, no debris on rails
Tires/Rollers	Visual inspection for wear	No cracks, embedded debris, or excessive wear

1.2 Safety Device Testing

Check Item	Test Method	Pass Criteria
Electromagnetic Brake	Release tiller, observe auto-lock	Immediate braking, no rolling
Emergency Reverse Button	Press button, observe equipment response	Equipment stops forward motion and reverses
Horn	Press horn button	Clear and loud sound
Warning Light	Turn on warning light	Flashes normally

1.3 Battery and Charge Inspection

Check Item	Method	Pass Criteria
Battery Level	Check dashboard indicator	Sufficient for daily operations
Battery Appearance	Visual inspection of casing and terminals	No swelling, corrosion, or leakage
Charging Interface	Check charging plug and socket	No looseness or burn marks

2. Weekly Maintenance Checklist

Weekly maintenance is typically completed within 30 minutes, focusing on cleaning and lubrication.

2.1 Cleaning Tasks

Cleaning Item	Method	Note
Body Surface	Wipe with damp cloth	Avoid direct washing of electrical components
Radiator	Blow with compressed air	Maintain good heat dissipation
Battery Surface	Wipe with dry cloth	Keep dry and clean to prevent terminal corrosion
Mast Rails	Remove dust and debris	Avoid grease contamination

2.2 Lubrication Tasks

Lubrication Point	Method	Frequency
Mast Rails	Apply grease	Weekly
Chain Pins	Apply lubricating oil	Weekly
Roller Bearings	Apply grease	Weekly
Tiller Pivot	Apply lubricating oil	Weekly

2.3 Function Verification

Lifting Test: Raise forks to maximum height with no load; observe smooth lifting and lowering, no abnormal noise
Travel Test: Run forward and backward; confirm smooth travel and no deviation
Steering Test: Turn left and right; confirm flexible tiller control and no jamming

3. Monthly Maintenance Checklist

Monthly maintenance is typically completed within 1-2 hours and should be performed by personnel with technical capability.

3.1 Motor Inspection

The CDDA20 is equipped with AC motors with brushless design, but insulation resistance still requires periodic testing.

Check Item	Method	Pass Criteria
Insulation Resistance	Measure with 250V megohmmeter	Cold insulation resistance >0.5MΩ
Motor Surface	Visual inspection	No dust accumulation, good heat dissipation
Terminals	Check tightness	No looseness or oxidation
Running Noise	Listen to operating sound	No abnormal noise or vibration

3.2 Hydraulic System Inspection

Check Item	Method	Pass Criteria
Hydraulic Oil Level	Check oil gauge	Between upper and lower marks
Oil Quality	Visual inspection of color	Clear, no emulsification or impurities
Hose Fittings	Visual inspection	No leakage or aging cracks
Cylinder Seals	Visual inspection	No oil seepage

3.3 Deep Battery Inspection

Check Item	Method	Pass Criteria
Terminal Corrosion	Visual inspection of terminals	No white/green corrosion
Connection Bolts	Check tightness with wrench	No looseness
Charger Function	Connect charger, observe status	Normal charging, indicator lights normal
Equalizing Charge	Perform every 3 months (gel battery)	Complete equalizing charge process

4. Maintenance Records and Abnormality Reporting

4.1 Maintenance Log

It is recommended to establish a maintenance log for each machine, recording the following:

Date and Time: When maintenance was performed
Maintenance Type: Daily/weekly/monthly
Inspection Results: Whether each item passed
Parts Replaced: If any, record part name and quantity
Abnormalities: Issues found and how they were handled
Executor Signature: Confirm maintenance completion

4.2 Abnormality Reporting Process

If the following abnormalities are found during maintenance, stop use immediately and report:

Brake Failure: Electromagnetic brake fails to lock properly
Hydraulic Leakage: Visible seepage from hoses or cylinders
Structural Deformation: Visible deformation of mast or forks
Electrical Fault: Motor noise, burnt wiring, insulation resistance below standard

5. Common Maintenance Pitfalls

Pitfall	Consequence	Correct Practice
Only checking battery level daily, ignoring brake test	Brake failure not detected in time	Test electromagnetic brake daily
Gel battery stored without charging for long periods	Battery sulfation, capacity loss	Recharge every 1-2 months
Applying excessive grease during lubrication	Attracts dust, accelerates wear	Apply moderate amount, remove excess
Neglecting insulation resistance testing	Motor fault hazards accumulate	Test insulation resistance monthly
Missing maintenance records	Cannot trace fault causes	Establish complete maintenance log

6. Conclusion and Action Recommendations

Daily maintenance of an Electric Pallet Stacker comes down to "checklist-driven execution, cyclical progression, and record-based traceability." Through the three-tier system of daily pre-shift checks, weekly cleaning and lubrication, and monthly deep inspection, most fault hazards can be eliminated at the early stage.
