With load capacities of 1200 kg (WSA121) and 1600 kg (WSA161), the WSA Series offers heavy-duty performance with exceptional precision. Capable of lifting up to 4.5 meters in just 15 seconds, these stackers maximize turnover efficiency. Their compact chassis and reduced turning radius make them ideal for narrow aisles, while the Li-ion battery with integrated charger ensures rapid, maintenance-free charging.
The WSA Series achieves lift heights of up to 4.5 m in just 15 seconds, dramatically improving stacking speed. The proportional lifting system ensures precise pallet placement in multi-level racking.
Fast and precise stacking
The redesigned cover includes a storage pocket and USB charging outlet, letting operators store documents or recharge devices while working. Ergonomic tiller design and creep speed mode further enhance safe and comfortable operation.
User-friendly details
With shorter length to face of forks and reduced turning radius (as low as 1446 mm), the WSA stackers are perfect for confined aisles. The WSA161 includes two side cylinders as standard, improving operator visibility during lifting.
Compact design with great visibility
Equipped with a 24V/100Ah Li-ion battery and integrated charger, the WSA Series supports fast, flexible charging and zero maintenance. Optional larger 205Ah Li-ion batteries extend operating time for multi-shift applications.
Advanced Li-ion power system
Application
The WSA Series is designed for intensive warehouse operations, distribution centers, and logistics facilities where stacking speed, precision, and uptime are critical. Thanks to proportional lifting control, operators can stack pallets smoothly and safely, even in multi-level racking. Compact size and improved visibility make the WSA Series highly effective in confined areas, while its strong mast options provide reliable residual capacity at high lift levels.
