  • Patent number: 8950774
    Abstract: A frame locking bar is supported pivotably with respect to a rear body. The frame locking bar is constructed to be able to lock an articulated structure by fixing a front body and the rear body to each other to thereby prevent swing thereof. A fixing mechanism is constructed to be able to position this frame locking bar at a prescribed pivoted position in a cantilevered state. At the positioned prescribed pivoted position, when viewed from above, a foot mount is located outside a side surface of a driver's compartment. Thus, a wheel loader capable of locking an articulated mechanism and allowing easy and highly safe services at a high position is obtained.
