I. Basic Inspection and Cleaning
Component Tightening and Leakage Inspection
It is necessary to check the tightening status of key components such as the fork carriage, wheel screws, and lifting chain every day to prevent potential safety hazards caused by looseness.
Focus on inspecting for leaks in parts such as hydraulic oil pipes, brake pumps, and cylinders, and replace aging seals in a timely manner.
Deep Cleaning
Remove dirt from areas such as the fork carriage slideways and battery electrodes to avoid corrosion and electrical short circuits.
II. Core System Maintenance
Hydraulic and Braking Systems
Regularly replace the sediment in the hydraulic oil filter to maintain the cleanliness of the oil and ensure smooth lifting and tilting operations.
Check the sensitivity of the brake pedal. The handbrake force should be less than 300N to prevent brake failure.
Battery and Power Management (Electric Forklift)
Keep the electrolyte level between the scale lines, and give priority to adding distilled water instead of ordinary water.
Avoid placing the battery horizontally to prevent the exposure of the electrode plates and extend the battery life.
III. Periodic Special Maintenance
Tire and Steering System: Check the tire pressure and wear condition every week. If the rim is deformed, it must be replaced immediately; lubricate the steering gear gears regularly to ensure the flexibility of operation.
Maintenance for Long-term Out-of-use: Before the forklift is out of use, the fuel tank needs to be emptied, and components such as bearings need to be lubricated twice. When restarting, it needs to run in at a low speed for 50 hours.
IV. Industry Trends and Suggestions
In recent years, intelligent forklift maintenance tools (such as Internet of Things sensors) have been gradually popularized and can monitor the equipment status in real time. Experts suggest that enterprises combine manual inspections with digital management to establish a "preventive maintenance" system to further reduce the sudden failure rate.
