The J3.50-4.00EX forklift offers a 3,500–4,000 lb load capacity with a 48V electric power source, ideal for warehouse logistics. Key specs include a 18–22 kW motor, 600–800 Ah battery options, and compact dimensions (L: 4.2m, W: 1.5m). Features like corrosion-resistant frames and regenerative braking optimize durability and efficiency. Always verify voltage compatibility with charging stations to prevent system mismatch.

What defines the J3.50-4.00EX model’s load capacity?
The J3.50-4.00EX handles 3,500–4,000 lbs via a reinforced mast design and dual front wheels. Its center of gravity calibration ensures stability at max load, critical for stacking pallets in narrow aisles. Pro Tip: Avoid exceeding 85% capacity on inclines—excessive strain accelerates motor wear.

Technically, load capacity depends on mast height: 4,000 lbs at 3m drops to 3,200 lbs at 6m due to leverage forces. The dual-stage hydraulic system prioritizes speed under 2,000 lbs and torque for heavier lifts. Think of it like a car’s gearbox—lower “gears” handle heavier weights. Why risk tipping? Always secure loads asymmetrically. For example, a 3,800 lb pallet at 4m height requires counterweight adjustments, achievable via the onboard stability algorithm.
| Load (lbs) | Max Mast Height | Lift Speed (m/s) |
|---|---|---|
| 4,000 | 3m | 0.35 |
| 3,500 | 4.5m | 0.5 |
| 3,000 | 6m | 0.7 |
What power source options are available?
The J3.50-4.00EX uses 48V lithium-ion or 36V lead-acid batteries, with modular trays for quick swaps. Lithium packs (600–800 Ah) reduce downtime via 1.5-hour fast charging, while lead-acid requires 8+ hours. Warning: Mixing battery chemistries voids warranties.

Standard lithium configurations deliver 18–22 kW continuous power with 2,000+ cycles. Comparatively, lead-acid provides 12–15 kW but loses 30% capacity after 500 cycles. Ever seen a smartphone battery degrade? Lead-acid ages similarly. Pro Tip: Opt for lithium in multi-shift operations—less maintenance and higher energy density. The BMS monitors cell balance, preventing over-discharge below 20% SOC. Critical: Use only UL-certified chargers to avoid thermal runaway risks.
| Battery Type | Cycle Life | Charging Time |
|---|---|---|
| LiFePO4 | 2,000+ | 1.5 hrs |
| Lead-Acid | 500–800 | 8–10 hrs |
What are the dimensions and weight specifications?
The forklift measures 4.2m (L) x 1.5m (W) with a turning radius under 2m, suited for tight spaces. Total weight hits 6,200 lbs unloaded—distribution is 60% rear, 40% front. Pro Tip: Floor load limits must exceed 7,500 lbs/m² to prevent surface damage.
Overhead guard height is 2.1m, compatible with standard dock doors. But what if your facility has low clearance? The foldable ROPS option reduces height to 1.8m. For example, a 3,800 lb payload adds 2,900 lbs to the front axle—ensure aisle widths exceed 3m for safe maneuvering. Always check the tire pressure (12–14 PSI for cushion tires) to optimize traction and minimize wear.
What safety features are included?
Standard features include LED headlights, auto-braking on inclines, and a load-sensing seat that disables movement if the operator exits. The anti-slip platform meets ANSI 2024 standards.
Practically speaking, the 360° camera system detects obstacles within 2m, even in low light. Think of it as a parking sensor for forklifts. The dual-circuit hydraulic brake stops 50% faster than single-circuit models. Pro Tip: Test emergency brakes monthly—corroded cables increase stopping distance by 1.5x. Warning: Overriding seat sensors risks uncontrolled movement; fines for OSHA non-compliance exceed $15,000 per incident.
What applications suit the J3.50-4.00EX best?
Ideal for cold storage (–20°C operation), steel mills, and automotive parts handling. The sealed electronics withstand IP54 dust/water exposure.
Beyond warehouses, its high torque suits construction sites unloading shipping containers. Why use a less durable model? The hardened forks (HRC 45) tolerate 10,000+ lift cycles without deformation. For example, a BMW plant uses 12 units for engine block transport—each handles 68 daily lifts without downtime. Pro Tip: Pair with telemetry systems to track utilization rates and schedule predictive maintenance.
How does it compare to similar models?
Versus the J3.00-3.50EX, the J3.50-4.00EX offers 15% higher lift speeds and 10% longer battery life. However, it’s 8% wider—unsuitable for sub-2m aisles.
The Cat® EPC5000 matches its capacity but lacks regenerative braking, increasing energy costs by 18%. Still need convincing? The J3.50-4.00EX’s diagnostic port simplifies troubleshooting via Bluetooth apps. For instance, a Toyota dealer reduced repair time by 40% using real-time fault codes. Critical: Cross-check dealer service plans—third-party parts may void the 3-year powertrain warranty.

FAQs
Yes, but only with kits featuring a 48V BMS and CANBus compatibility. Non-integrated packs may disable safety protocols.
How often should hydraulic fluids be changed?
Every 1,000 operating hours or annually—whichever comes first. Contaminated fluid reduces lift speeds by up to 50%.
