Vibration System Force Rating from 2,000 kgf to 7,000 kgf

Ideal for test applications such as packaging testing and vehicle testing.

The Long-Stroke (LS) Series vibration testing systems are designed for long-stroke displacement test requirements normally performed by hydraulic shakers. Compared to a hydraulic shaker where maximum test frequency is typically around 400 Hz, the Long-Stroke Series is capable to testing up to 2,700 Hz with maximum acceleration of 100g (bare table) bounded by 2.0 m/s maximum velocity. This provides users time and cost savings for wide test requirements.
