  LS Series Vibration Test System
 
 

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 3,000 Hz with a maximum of 100 g (bare table) bounded by 2m/s maximum velocity. This provides users time and cost saving for wide test requirements. These shakers are suitable for test application such as package testing and vehicle testing.

Features:

The Performance:
Specimen payload to 800kg (17,600lbs)
