  • Patent number: 6402454
    Abstract: A forklift, in which, if a synchronous mode change-over switch is depressed, a forward/backward moving lever is switched over to the backward moving side, and a throttle pedal is stepped down, then a pusher is moved forward by a pusher cylinder in synchronization with the backward movement of the vehicle body of the forklift to thereby push out baggage carried on a fork therefrom. An oil pressure circuit connects together a pusher cylinder and an oil pressure pump. A hand-operated switch valve 21 is disposed in the oil pressure circuit. A valve full-open switch 22 opposes a projection portion 25 provided on and projected from a pusher lever 12 which is used to switch the state of the hand-operated switch valve 21. When the pusher lever 12 fully opens the hand-operated switch valve 21, the projection portion 25 contacts with the valve full-open switch 22 to thereby allow the valve full-open switch 22 to issue a detect signal to a control part of the forklift.
