W25-30ZA2 and W40ZA pallet stackers are electric-powered material handling machines designed for efficient vertical stacking in warehouses. These models feature compact designs, hydraulic lift systems, and load capacities ranging from 2,500 to 3,000 kg. Optimized for fast-cycle operations, they use LiFePO4 or lead-acid batteries (24V–48V), achieving lift heights up to 4.2 meters. Ideal for narrow aisles, their maneuverability reduces downtime in logistics and manufacturing workflows.

Built with hardened steel masts and wear-resistant polyurethane tires, these stackers handle 8–12 hour shifts effortlessly. Their AC drive motors provide consistent torque, even at full load. For example, the W25-30ZA2’s 24V 210Ah LiFePO4 battery enables 18–20 lifts per hour in cold storage. Transitionally, operators benefit from automatic speed reduction when lifting—preventing tip-overs. Warning: Avoid overloading beyond 110% capacity, as it strains the hydraulic pump and voids warranties.
| Feature | W25-30ZA2 | W40ZA |
|---|---|---|
| Load Capacity | 2,500 kg | 3,000 kg |
| Lift Height | 4.0 m | 4.2 m |
| Battery Voltage | 24V | 48V |
Where are these pallet stackers commonly used?
They excel in high-density warehouses and retail distribution centers. Applications include cross-docking, cold storage, and manufacturing assembly lines. Their tight turning radius (1.3 m) suits environments with narrow aisles under 2.2 meters wide.

In practice, a beverage distributor using W40ZA models reported a 25% throughput increase due to faster battery swaps. Transitionally, LiFePO4’s -20°C to 60°C operating range ensures reliability in unregulated climates. Pro Tip: Programmable travel speeds (0–8 km/h) let operators customize workflows—slower speeds enhance precision near racks. Real-world example: A 3PL provider cut energy costs by 30% after switching to 48V 400Ah LiFePO4 packs from Redway Battery.
What battery systems power these stackers?
Options include 24V lead-acid (210–250Ah) or LiFePO4 (150–400Ah). Lithium variants offer 3,000+ cycles vs. 1,200 for lead-acid. Charging terminates at 29.2V (24V) or 58.4V (48V) to preserve cell health.
For instance, a 48V 400Ah LiFePO4 battery provides 19.2 kWh, sustaining 6–8 hours of continuous use. Transitionally, integrated battery management systems (BMS) prevent deep discharges below 20% SOC. Did you know? Lithium batteries maintain 85% capacity after 2,000 cycles, whereas lead-acid degrades to 50% in 800 cycles. Always pair batteries with OEM-approved chargers—mismatched voltages can trigger BMS faults.
| Battery Type | Cycle Life | Charge Time |
|---|---|---|
| LiFePO4 | 3,000+ | 2–3 hrs |
| Lead-Acid | 800–1,200 | 8–10 hrs |

How do W25-30ZA2 models compare to traditional stackers?
They outperform legacy units in energy efficiency and operator safety. AC motors reduce energy waste by 15–20%, while auto-braking prevents free-roll incidents.
Traditional stackers often lack load-sensing hydraulics, leading to jerky lifts. In contrast, the W25-30ZA2’s dual-pump system adjusts oil flow based on weight. For example, a 1,500 kg load triggers a 25% slower lift to minimize hydraulic stress. Pro Tip: Monthly inspections of mast roller guides prevent uneven wear—replace if lateral play exceeds 3 mm. Transitionally, their modular design allows easy component swaps, cutting repair time by 50% versus welded-frame competitors.

FAQs
Lead-acid: 18–24 months. LiFePO4: 8–10 years. Monitor capacity drops below 80%—swap batteries once weekly runtime falls under 4 hours.
Can these stackers handle uneven floors?
Yes, but limit grade angles to 3°. Exceeding this risks motor overload. Use polyurethane tires for gravel or asphalt surfaces.
