Abstract:
    The invention provides a laser level detection system which is needless of changing the installing position of the level detection means even in the case where different leveling parts of different heights are leveled respectively. The system comprises: the rotational laser device for making the reference surface for rotating the laser beam around the axis as well as emitting the laser beam; the level detection means for detecting the height of the bucket of the shovel car by receiving the laser beam; and the operation device arranged in the driving room. The level detection means comprises: a plurality of level detection devices arranged in a vertical direction, each level detection device extends in vertical direction and provided with a light receiving part for receiving the laser beam, and outputs the data corresponding to the difference of reference light receiving position of the laser beam, the operation device receives the data and displays the difference by receiving the data.
