The SEER SSS-2000EU is a CE-certified (ISO 3691-4:2023) slim stacker autonomous forklift with a 2-ton load capacity. It measures 1,724 by 1,039 by 1,995 to 2,229 mm and weighs 950 to 1,175 kg depending on 1,600 or 3,000 mm lift height, with a 600 mm load center distance and 1,336 mm minimum turning radius. Forks measure 1,220 by 180 by 60 mm with 555, 600, or 680 mm outer widths. AI deep learning recognizes pallets, racks, and cages in different colors and sizes with multi-angle adaptive high-precision recognition. A 360-degree wide-range scanning system uses 2D safety avoidance lasers, distance sensors, and pallet recognition cameras. A 24 V 210 Ah lithium iron phosphate battery provides 10-hour runtime with 2 to 2.5-hour charging. Speeds reach 1.5 m/s full load and 1.8 m/s no load with ±10 mm and ±0.5-degree positioning accuracy. Right-angle stacking aisle widths range from 1,892 to 2,003 mm plus 200 mm. Standard features include E-stop, sound and light indicator, 360-degree laser protection, bumper strip, fork height protection, 3D obstacle avoidance, pallet recognition, and HMI display. Cage stack, high shelf pallet recognition, and pallet stack are optional. Customizable fork width, robot height, color, and logo are supported. Targets industrial logistics and warehouse stacking operations.
