A compact damper test machine for verifying the damper forces within  specified tolerances levels. The machine can test dampers both in lateral and vertical position. This is useful as part of regular maintenance, to test that your dampers are working correctly, or after refurbishment to ensure that the dampers are back to their original specification. All this  ensures a safe and comfortable ride for your passengers. The machine has been given a straightforward, purposeful design according to customer demands for easy operation.
