The SEER SFL-CDD14 and SSS-1400EU are small stacker autonomous forklifts available in CE and non-CE versions for global markets, with a 1,400 kg rated load capacity and 600 mm load center distance. The domestic SFL-CDD14 measures 1,704 by 977 by 1,998 to 2,113 mm depending on 1,600 or 3,000 mm lift height and weighs 680 kg with a 1,221 mm turning radius. The CE-certified SSS-1400EU measures 1,766 by 969 by 2,064 to 2,142 mm and weighs 740 kg with a 1,269 mm turning radius. Both use 1,220 by 180 by 70 mm forks with 570 to 680 mm outer widths. SLAM navigation achieves ±10 mm and ±0.5-degree accuracy without reflectors. A 360-degree stereoscopic protection system uses 3D obstacle avoidance, bumper strips, and distance sensors. A 24 V 210 Ah lithium iron phosphate battery provides 10-hour runtime with 2-hour charging. Speed is 1.2 m/s full load and 1.5 m/s no load with under 5 percent slope, 5 mm step, and 15 mm gap passability. Right-angle stacking aisle widths vary by pallet configuration from 1,822 to 1,966 mm plus 200 mm. Braking distance is under 30 cm at 1 m/s. Standard safety features include E-stop, sound and light indicator, 360-degree laser protection, bumper strip, and fork height protection (CE version). The CE version adds ISO 3691-4, EMC, and UN38.3 certifications. Optional features include 3D obstacle avoidance, pallet recognition, cage stack, high shelf pallet recognition, pallet stack, and HMI display. Targets industrial logistics and warehouse stacking operations.
