Abstract:
1. A full crowd detent apparatus of a wheel loader bucket, comprising: a bucket position holding unit configured to latch a joystick lever operating a bucket while a power is supplied; a bucket position detecting unit configured to detect the position of the bucket by acquiring a bucket angle value from an angle sensor detecting a rotational angle of the bucket; a bucket position judging unit configured to judge whether the detected position of the bucket is within or second on operation sections, corresponding respectively to bucket positions within a range from a maximum dump position to a loading position and to bucket positions within a range from the loading position to a full crowd position, in which an electromagnet of the bucket position holding unit is turned on, and whether the detected position of the bucket is within first or second off operation sections, corresponding respectively to the loading position and the full crowd position, in which the electromagnet of the bucket position holding unit is turned off; and a bucket detent controlling unit configured to supply the power when the judged position of the bucket is within the first or second on operation sections and interrupt the power when the judged position of the bucket is within the first or second off operation sections.
