Structure characteristics:
1. Motor drive the testing platform, the frequency transformer control the motor rotation speed and speed conversion
2. Precision manual pressure regulating valve ensure to get the stable and reliable output force and indicate from the digital display.
3. The output end of the cylinder attached the gimbal, adapt to different angles of the chair surface.
4. Simple clamping structure, self-aligning, chair legs without vertical stress, simulate the actual state.
5. Air cylinder out-force in height is adjustable, adapt to different height of chair.

Parameter:
1. Digital rotation frequency RPM: 5~15CPM.
2. Angle of rotation: Repeated swing or rotate in a single direction.
3. Out-force: 158.5KgF
4. Special mechanical design ensure the center of gravity of the load is 2 to 2.5 in forward of the centerline of the rotational axis.
5. Count range: 0~999999, Stop / off memory function.
6. Bearing surface height (seat): 350~800mm
7. Turntable diameter: 740mm
