HARDNESS MEASURING VEHICLE OF RIDING GROUND

摘要

PROBLEM TO BE SOLVED: To provide a hardness measuring vehicle of a riding ground capable of rapidly and simply measuring the hardness of the riding ground. SOLUTION: The hardness measuring vehicle 1 of the riding ground running on the riding ground to measure the hardness of the riding ground is constituted by loading the chassis with an impact force sensor part 4 dropped toward the riding ground from the holding position separated by a predetermined height from the riding ground to detect impact force at the time of collision with the riding ground, a holding part 5 for holding the impact force sensor part 4 at the holding position and releasing the holding of the impact force sensor part 4 at a measuring point and a moving part 7 for moving the impact force sensor part 4, which has been collided with the riding ground, to the holding position.
