Explore the ESA121 Duplex
With a 1200 kg load capacity and lift height up to 4.1 meters, the ESA121 Duplex offers excellent stability and visibility through its H-beam mast with two side lifting cylinders. Faster lifting and lowering speeds improve efficiency, while optional proportional lifting ensures smoother, more precise handling. An optional free-lift mast enables safe operation in low-clearance areas. Powered by either AGM or Li-ion batteries with integrated charger, it provides convenience and flexibility for daily warehouse operations.
The H-beam duplex mast with two side cylinders provides excellent visibility and high rigidity. This reduces frame torsion when lifting heavy loads and ensures stability, with residual capacity of 800 kg at 3.6 m. For further usage in height-restricted environments, the optional free-lift mast improves safety and maneuverability without compromising lifting performance.
High visibility Robust duplex mast with freelift option
Equipped with a powerful 3.0 kW lift motor, the ESA121 Duplex offers faster lifting and lowering speeds of it’s class. This improves cycle times and increases overall warehouse productivity.
Optional proportional lifting ensures precise positioning when stacking or retrieving pallets, reduces load sway, and minimizes the risk of product damage. It is especially valuable in high-density storage and applications requiring careful load placement, improving both safety and operational efficiency.
Fast lifting and lowering performance with accurate control
Available with both AGM and Li-ion batteries, the ESA121 Duplex meets different operational needs. The integrated charger simplifies daily charging, while maintenance-free technology reduces downtime and cost.
Flexible battery solutions
Featuring a redesigned cover with storage pockets for documents, objects, and even cups, plus an optional USB port, the ESA121 Duplex is built with operator convenience in mind. Ergonomic tiller and turtle speed mode ensure safe and comfortable operation.
User-centered design
Application
The ESA121 Duplex is designed for warehouses, retail, and distribution centers requiring medium stacking heights up to 4.1 m. Its compact chassis (826 mm width) and turning radius of 1480 mm make it suitable for use in narrow aisles. An optional free-lift mast enables safe operation in containers and low-ceiling spaces. Creep speed mode and an ergonomic tiller support safe, precise pallet handling in confined areas, while optional proportional lifting control allows accurate load positioning in high-density operations. A reinforced mast ensures strong residual capacity even at higher lift heights.
