  • Patent number: 6901323
    Abstract: 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).

  • Patent number: 6767175
    Abstract: 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.

  • Publication number: 20030024132
    Abstract: A cargo handling vehicle comprises cargo carriers 21, a lift unit 1, a vehicle main body 24, and a running system 3, and the cargo handling vehicle further comprises a lift height detecting section 2 for detecting the vertical position of the cargo carriers 21, a traveling distance measuring section 4 for measuring a forward distance S1 covered by the vehicle main body 24 which starts its forward movement after the cargo carriers 21 are started to be raised and a rearward distance S2 covered by the vehicle main body 24 which starts its rearward movement after having completed its forward movement, and a movement control section 9 for prohibiting the lowering movement of the cargo carriers 21 until a rearward distance to be covered by the vehicle main body 24 which starts its rearward movement in a state in which the vertical position H2 of the raised cargo carriers 21 exceeds a preset reference height H1 becomes equal to or greater than the forward distance covered by the vehicle main body 24.
