Patent number: 12215012Abstract: A forklift includes a vehicle body, a fork that mounts a pallet, and a sensor provided in an insertion portion of the fork. The forklift inserts the insertion portion into an insertion opening, while moving the fork. When the sensor detects a proximity state, in which the insertion portion has approached a facing surface to such an extent that a distance between the insertion portion and the facing surface is less than or equal to a specified value, the forklift executes a stopping process that stops movement of the fork. The forklift executes an avoidance process that tilts and vertically moves, after the stopping process, the fork to separate the insertion portion away from the facing surface such that a position of the insertion portion with respect to an entrance of the insertion opening does not change in an up-down direction of the vehicle body.Type: GrantFiled: October 7, 2022Date of Patent: February 4, 2025Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Yukikazu Koide, Norihiko Kato, Daisuke Okabe
