The SEER SCB-1400 is a counterbalance autonomous forklift with a 1.4-ton rated load capacity and 500 mm load center distance. It measures 2,494 by 1,196 by 2,010 mm and weighs 2,600 kg with a 3,000 mm standard lift height and 1,299 mm minimum turning radius. The 1,196 mm body width is compatible with rack pallets, pallet cages, closed pallets, 4-way entry pallets, and 2-way entry pallets, with customizable overall height for multi-layer stacking and destacking. Forks measure 1,070 by 123 by 40 mm with adjustable width from 400 to 700 mm. AI deep learning recognizes diverse carriers including multi-spec, multi-color, stretch-wrapped, or damaged pallets with high-precision multi-angle adaptive recognition. Multi-sensor fusion integrates 3D navigation LiDAR with 360-degree wide-field-of-view scanning, safety obstacle-avoidance LiDAR, distance sensors, and pallet-recognition cameras for enhanced semantic scene understanding. A 25.6 V 200 Ah lithium iron phosphate battery provides 6 to 8 hours runtime with 2-hour fast charging and 2-minute quick battery swap. Speed is 1.0 m/s full load and 1.5 m/s no load with ±10 mm and ±1-degree positioning accuracy. It operates from 0 to 55 degrees C. Right-angle stacking aisle widths range from 2,531 to 2,719 mm plus 200 mm. Standard features include 3D obstacle avoidance, pallet recognition, and HMI display. Targets industrial manufacturing and logistics counterbalanced forklift applications.
