PROBLEM TO BE SOLVED: To provide a laser level detector for a hydraulic shovel capable of receiving laser beams at an accurate level even when an arm is inclined with respect to the water dripping direction.SOLUTION: A laser level detector 1 for a hydraulic shovel that is attached to an arm 100 of the hydraulic shovel and receives laser beams emitted from a laser level device includes: a light receiving unit 10 for receiving the laser beams; and a pivotally supporting unit 20 that is attached to the arm 100 for pivotally supporting a bucket 110 of the hydraulic shovel and turnably supporting the upper end of the light receiving unit 10. Even when the arm 100 of the hydraulic shovel is inclined with respect to the water dripping direction, the light receiving unit 10 turns about the pivotally supporting unit 20 due to gravity and receives laser beams.SELECTED DRAWING: Figure 1 |
