PURPOSE: A caterpillar track roller testing device is provided to increase performance efficiency and durability and to improve the accuracy and reliability of a test result since the speed of a track roller, the control of a rotational direction, and the applied direction and load are freely changeable. CONSTITUTION: A caterpillar track roller testing device comprises a rotational roller unit (10), a track roller (20) of a tested object, a vertical load control unit (30), and a horizontal load control unit. The rotational direction of the rotational roller unit is changeable. The track roller is rotated by being contacted with the upper side of the rotational roller unit. The vertical load control unit makes the track roller to be contacted with the rotational roller unit for rotation, and applies load to the track roller in the vertical direction. The horizontal load control unit applies load to the track roller in the horizontal direction, which is rotated by being contacted with the rotational roller unit, by moving the rotational roller unit side to side in the axial direction of the rotational roller unit. |
