The E4.0-5.5XN forklift series offers load capacities of 3,000–5,500 kg with lift heights up to 6.5 meters. Powered by 48V or 80V lithium-ion or lead-acid systems, these models feature robust AC traction motors for torque-sensitive tasks. Key specs include 3-stage mast configurations, 400–600 mm load centers, and ergonomic controls for precise handling in warehouses and logistics hubs. 48V 400Ah/420Ah Forklift Lithium Battery
What load capacities do E4.0-5.5XN forklifts support?
These forklifts handle 3,000–5,500 kg loads, ideal for medium-to-heavy palletized goods. Saturation voltage peaks at 5.5 kN ensure stability during high-stress lifts.
E4.0-5.5XN forklifts employ reinforced counterweights and dual-cylinder hydraulic systems to manage heavy loads. For example, lifting 5,500 kg to 4 meters requires 48V/600Ah LiFePO4 batteries sustaining 220A draw. Pro Tip: Always check load center adjustments—using 550+ mm centers reduces effective capacity by 12–15%. Beyond raw power, their trapezoidal mast design minimizes lateral sway during height transitions. But how do operators ensure load safety? Regular torque checks on lift chains (rated for 8,000 kg break strength) prevent slippage under asymmetric weights.

How do E4.0-5.5XN power systems differ?
Options include 80V AC motors or 48V DC variants, with energy storage from lithium-ion or lead-acid packs. Thermal management varies by voltage tier.

The 80V system prioritizes torque (up to 420 Nm) for slopes up to 15%, while 48V models optimize for runtime in flat warehouses. For instance, an 80V LiFePO4 battery delivers 120Ah capacity, enabling 6-hour shifts with 85% depth of discharge. Pro Tip: Lithium-ion packs recharge 3x faster than lead-acid—pair with 30A chargers for midday top-ups. Transitioning between power types? AC motors offer regenerative braking, recapturing 12–18% energy during deceleration. What’s the cost trade-off? Upfront lithium costs are 2x higher but lifespan exceeds 2,000 cycles versus 500 for lead-acid.
| Power System | Voltage | Energy Efficiency |
|---|---|---|
| AC Motor | 80V | 92% |
| DC Motor | 48V | 87% |
What mast configurations are available?
Choose 2-stage or 3-stage masts with lift heights of 3–6.5 meters. Free lift heights adjust from 150–300 mm for low-clearance stacking.
Three-stage masts use telescoping rails with dual roller bearings for smooth extension. A 6.5-meter lift requires 24V hydraulic pumps generating 170 bar pressure—critical for speed (up to 0.5 m/s). Pro Tip: Lubricate mast rails monthly with ISO VG 68 oil to prevent jerky lifts. Imagine stacking pallets in a 7-meter rack—without free lift, the mast’s collapsed height would block aisle visibility. Why risk downtime? Contaminated hydraulic fluid causes 30% of mast failures.
How maneuverable are these forklifts?
Turning radii as tight as 1.8 meters and responsive pivot points enable navigation in narrow aisles. Rear-axle oscillation (±3°) improves traction on uneven surfaces.
The E4.0-5.5XN series features automatic traction control adjusting wheel slip during sharp turns. For example, a 2-ton load at 10 km/h requires 12° steering angle increments to prevent tip-overs. Pro Tip: Enable “creep mode” (0.3 km/h) when operating within 10 cm of racking edges. What happens during emergency stops? Dual-circuit disc brakes decelerate from 15 km/h to zero in 3 meters without load shift.
| Feature | E4.0-5.5XN | Competitor A |
|---|---|---|
| Turning Radius | 1.8 m | 2.2 m |
| Max Speed | 15 km/h | 12 km/h |
What durability features are included?
Fully sealed IP54 electricals and 8 mm steel plate frames withstand impacts up to 12 kJ. Corrosion-resistant coatings add 5+ years lifespan in humid environments.
The modular design allows component swaps—replacing a damaged 80V controller takes <45 minutes. Pro Tip: Inspect undercarriage scrapers weekly; debris buildup accelerates drive motor wear. Imagine a forklift operating in a seafood warehouse—stainless steel brake lines prevent saltwater-induced rust. But how durable are the tires? Solid-rubber variants last 1,200 hours vs. 800 for pneumatics on rough concrete. Forklift Lithium Battery Category

FAQs
Yes, but verify BMS compatibility—older chargers may lack LiFePO4 voltage profiles, requiring firmware updates.
What’s the maximum mast height without rear counterweight modification?
6.5 meters—beyond this, counterweights need +15% mass to balance elevated loads safely.
