Abstract

PURPOSE:To fail in selection of travelling wheels by means of a travelling wheel selective switch only by configurating a circuit in such a manner that a travelling electric circuit which connects the steering wheel selective switch and a travelling change-over valve cannot be closed without having releasing the lock of travelling of rear wheels. CONSTITUTION:The travelling by means of front wheels 11 only is performed by opening a travelling wheel selective switch 35 and a rear wheel locking change- over switch 38 and positioning a travelling change-over valve 16 in neutral, thereby supplying oil into a front wheel travelling cylinder 11 only from a tank 13. For travelling by the front wheels 11 only, a power is fed from a power supply A to a solenoid 24g of the rear wheel locking change-over valve 24 via relays 37p, 37q to change over the rear wheel locking change-over valve 24. Hence, the oil is sent from the tank 13 to a locking cylinder 22 to operate a lock pin 29 for locking the steering of the rear wheels. Once the switch 38 is closed, the valve 24 is shifted to release the lock pin 29 and the change-over valve 16 is shifted from th neutral position so that travelling of the front and rear wheels may be enabled.
