Head Expanders

60" x 60" head expander on R16 shaker enables extra large product testing

Unholtz-Dickie offers a wide range of head expanders and head plates to maximize the versatility of any electrodynamic shaker. The head expanders are manufactured from light-weight magnesium alloys, providing high strength-to-weight ratio.

By increasing the mounting area of the shaker, multiple items can be tested at the same time, decreasing total test cycle time. In addition, with Guided Head Expanders and Added Load Support, heavy payloads with large foot prints can be safely mounted and tested on the shaker, minimizing the risk of damage to the shaker suspension system. Although many head expanders are resonant below 1000 Hz, average or extremal control allows operation to 2000 Hz.
