The Long Stroke (LS) Series Shakers 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 LS Series is capable of testing up to 2,500Hz with a maximum of 100g (bare table), bounded by 6.5 ft/s (2.0 m/s) maximum velocity. This provides users time, cost savings and wider test requirements. Suitable for application such as package, transportation and vehicle testing.
