The Long Stroke 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 400Hz. The Long Stroke Series is capable to testing up to 2,500Hz with a maximum of 80g (bare table) bounded by 1.8m/s maximum velocity. This provides users time and cost savings for wide test requirements. These shakers are suitable for test applications such as package testing and vehicle testing.
