The J4.0-5.5-XN electric forklift features a 4,000–5,500 lb load capacity and 20-foot lift height, powered by a 48V LiFePO4 battery with 2,000+ cycles. Its AC motor enables 12 mph travel speeds, while regenerative braking recovers 15–20% energy during deceleration. Advanced IoT telematics provide real-time diagnostics, and the ergonomic design reduces operator fatigue by 30% versus traditional models.

What load capabilities define the J4.0-5.5-XN?
This model handles 4,000–5,500 lbs across 24″ load centers, with a 24-volt AC motor delivering 12.5 kW peak power. Stability is ensured via a 43.3″ wheelbase and 6.7° tilt angle.

Beyond raw numbers, the J4.0-5.5-XN uses load-sensing hydraulics to auto-adjust pump flow—reducing energy waste when lifting partial loads. Pro Tip: Distribute weight evenly on the forks; uneven loads over 3° tilt risk tip-overs. For example, moving 4,800 lbs of palletized cement bags at a 15-foot height consumes 35% battery per 8-hour shift. Transitionally, lower centers of gravity allow heavier lifts without compromising maneuverability.
How does its LiFePO4 battery enhance performance?
The 48V 600Ah LiFePO4 battery provides 28.8 kWh capacity, charging fully in 2 hours vs. 8–10 hours for lead-acid.

LiFePO4 chemistry maintains 80% capacity after 2,000 cycles—tripling lead-acid lifespan. But what makes it warehouse-ready? Built-in BMS thermal regulation allows operation from -4°F to 140°F. Practically speaking, a single charge supports 6–8 hours of mixed lifting/driving. Pro Tip: Store batteries at 50% charge during long inactivity to prevent sulfation. Imagine a Tesla-like powertrain: rapid charging, consistent output, and zero maintenance—no water refills or terminal cleaning required.

|---|---|---|
| Cycle Life | 2,000+ | 500–800 |
| Charge Time | 2 hrs | 8–10 hrs |
What smart technologies are integrated?
IoT-enabled CAN-BUS diagnostics track battery health, motor temps, and hydraulic pressure in real-time via 4G/Wi-Fi.
Fleet managers receive predictive alerts—like impending bearing wear or brake pad replacements—cutting downtime by 25%. Transitionally, the system syncs with warehouse management software to optimize travel paths. How does this impact daily operations? Imagine Amazon’s Kiva robots: the forklift auto-adjusts speed limits near pedestrian zones and logs load data into ERP systems. Pro Tip: Update firmware quarterly; v2.3 (2024) added anti-collision zone mapping.
What safety mechanisms prevent accidents?
Regenerative braking, automatic descent control, and 360° ultrasonic sensors mitigate collision risks.
The braking system recovers energy while maintaining 3.5 ft/s² deceleration—critical when carrying suspended loads. Meanwhile, descent control prevents free-fall if hydraulic pressure drops. For example, when lifting pallets over icy docks, the sensors detect nearby workers and limit travel speed to 5 mph. Pro Tip: Conduct weekly sensitivity tests on obstacle detectors—dust accumulation can delay response by 0.8 seconds.

How does it compare to internal combustion forklifts?
Zero emissions, 60% lower operating costs, and 40 dB noise reduction make it ideal for food/pharma warehouses.
Though diesel rivals have higher initial lift speeds (15 mph vs. 12 mph), the J4.0-5.5-XN dominates in lifetime costs. For instance, over 10,000 hours, fuel savings exceed $28,000. But what about torque? The AC motor’s 430 N⋅m outperforms most 4.3L LPG engines. Transitionally, electric models avoid indoor air quality issues—no CO monitoring required.

FAQs
Yes, with IP54-rated components and pneumatic tires, it handles wet/uneven surfaces—but avoid prolonged exposure to heavy rain.
What’s the battery replacement cost?
~$6,800 for a 600Ah LiFePO4 pack, versus $2,200 for lead-acid—but 3x lifespan offsets the premium.
Does it support third-party attachments?
Yes—carton clamps, rotators, and sideshifters up to 800 lbs, provided they’re CAL-OSHA compliant.
