Patent number: 11739925Abstract: A forklift 1 as a cargo vehicle includes: a vehicle body 1A which an operator M gets on; and an image projection device 31, projecting an image related to vehicle information in a direction (left) in which the operator M alights to display the image on a road surface G. In addition, the forklift 1 further includes an alighting sensor that detects an alighting operation when the operator M alights. The image projection device 31 projects the image when the alighting sensor detects the alighting operation.Type: GrantFiled: August 2, 2022Date of Patent: August 29, 2023Assignee: Mitsubishi Logisnext Co., Ltd.Inventor: Kazumasa Kokura

Patent number: 6901323Abstract: Separately from a normal running mode, there is provided a turning mode in which a body (1) is allowed to turn. In the turning mode, road wheels (5a, 5b) and a driving wheel (8) are set such that the wheels are oriented so as to follow along a circumference R1 to R3 that would be formed about a distal end (B) of a fork arm (2b). As a result of this, the body (1) is allowed to turn about the distal end (B) of the fork arm (2b), whereby the body (1) can simply be positioned so as to confront the front of a pallet (40).Type: GrantFiled: November 27, 2001Date of Patent: May 31, 2005Assignee: Nippon Yusoki Co., Ltd.Inventor: Kazumasa Kokura

Patent number: 6767175Abstract: A forklift having a pallet lock device. On an upper face of a top end of a lock bar to lock a pallet, a tapered portion is disposed. When a fork is inserted into the pallet, the tapered portion comes into contact with an end face of the pallet and the lock bar rotates downward. When a landing sensor is turned on by a magnet disposed on the lock bar, the lock bar is immediately driven and the locking operation is started. Then, the top end of the lock bar pushes or comes into pressure contact with an upper face of a lower deck board of the pallet, and the pallet is locked.Type: GrantFiled: December 13, 2002Date of Patent: July 27, 2004Assignee: Nippon Yusoki Co., Ltd.Inventors: Tutomu Fujita, Yasunobu Tomiyama, Kazumasa Kokura
