For laboratory investigation of the resistance of packages and products to vibrations. Simulates the effects, which occur during transports by rail or other means. Executes a harmonic sinusoidal vertical or horizontal motion or a combination of both. The servo controlled DC motor maintains the preset vibration frequency independently of the size of the load. Maximum load 400 Kg, vibration frequency max. 13 1/3 Hz. Amplitude 0-12.7 mm (peak to peak 25.4 mm) Table area 1.25x1.5 m.
