ALPHA MLB Shaker

Compact and mobile shaker systems for complete vehicle and component testing

A movable base with integrated lever arm allows the combined use of ALPHA MLB shakers for complete vehicle and component testing. Due to the compact size, flexible positioning and connection of the ALPHA MLB shakers, modular extensible vibration tables for sequential and simultaneous excitation in 1 to 6 axes can be realized, which will grow with your requirements. Depending on the force requirement, several shakers can be used for excitation in one axis. 
The transmission of the excitation in the desired direction is achieved by an integrated lever arm – of course absolutely noiseless! At the same time, the lever arm protects the shaker from inadmissible bending moments and enables an optimum adaptation of the required forces and vibration displacements due to a selectable transmission ratio. Integrated electromagnets fix the shakers in the desired position by pressing a illuminated pushbutton directly at the movable base.
For quiet continuous operation even with high excitation forces or for use in a climatic chamber, these systems can also be optionally equipped with noiseless water cooling. Contact us to learn more about the new ALPHA MLB shakers..
