The gantry or fork of the reach-type forklift AGV can move forward and backward, and the front wheels can be extended to pick up and place goods. When walking, the fork carrying the goods
retracts so that the center of gravity of the goods is located within the support surface; the reach-type forklift has two extended legs, which can provide
stability.https://www.sinoracking.com/large-forward-stacking-mobile-robot-forklift-agv.html
