Battery-powered electric flat cars are essential for industrial material transfer. Simplified, targeted maintenance can extend service life and avoid operational failures. Below are core maintenance points from battery care, mechanical checks, electrical system protection, and basic operation norms.
I. Core Battery Maintenance (Critical for Endurance)
Use only the manufacturer's matching charger. Avoid overcharging (unplug after full charge) and deep discharge (charge when remaining power is 20%-30%).
Charge in a well-ventilated, dry environment. Avoid extreme temperatures (＜-10℃ or ＞45℃) during charging.
Regularly clean battery surfaces and terminals (wipe with dry cloth or alcohol for oxidation). For lead-acid batteries, top up with distilled water if electrolyte is low; lithium-ion batteries need loose terminal checks.
If idle for over 15 days, charge to 50%-60% and recharge every 1-2 months.
II. Mechanical System Maintenance
Weekly: Check frame bolts (tighten if loose) and wheels for wear/deformation. Ensure smooth wheel operation.
Quarterly: Add lubricating oil to bearings and transmission components to reduce friction.
Annually: Clean the vehicle body (remove dust/oil) and apply anti-rust treatment to metal parts (frame, wheel hubs).
For lifting models: Inspect hydraulic system for leaks monthly; replace worn chains/seals promptly.
III. Electrical System Maintenance
Check wiring harnesses regularly for aging, cracks, or exposed wires. Repair minor damage with insulating tape.
Ensure emergency stop buttons, limit switches, and anti-collision sensors are sensitive. Test emergency stop monthly.
Keep electrical components (motor, controller) away from water and dust. Install dust covers in dusty environments; dry thoroughly if wet.
Listen for abnormal motor noise/overheating during operation. Stop use immediately if issues occur.
IV. Basic Operation & Regular Schedule
Do not overload or drive violently (smooth start/accelerate/brake). Avoid rough roads or steep slopes beyond capacity.
Follow a simple maintenance schedule:
Daily: Check battery power and safety device sensitivity.
Weekly: Inspect bolts and wheel condition.
Monthly: Test safety functions and hydraulic leaks (if applicable).
Quarterly: Lubricate moving parts.
Annual: Comprehensive anti-rust and aging part replacement.
