Head Expanders & Fixtures

Effective and reliable solutions to increase productivity by allowing multiple items to be tested simultaneously, decreasing total test cycle time.

ETS Solutions offers Head Expanders for applications where larger vertical test mounting surfaces are required. Head Expanders are manufactured from lightweight magnesium alloy, providing high strength-to-weight ratio. A choice of less costly aluminium alloy is also available for smaller fixtures. The Head Expander allows multiple items to be tested at the same time, decreasing total test cycle time. Head Expanders with load support guidance allow payloads with large footprints to be safely mounted and tested on the shaker, reducing the risk of damage to the shaker suspension system.

The Guided Head Expanders are designed for testing of large, heavy packages to handle tough transportation and other demanding test profiles while providing additional restraints and load support.

Customized fixtures can also be designed and manufactured based on the customer’s specimen mounting requirement. Cube, L type and T type fixtures for testing of multiple small sized components are available. The customized cube, L or T types are preferred by customers for three axis testing without investing in an additional slip table.

The latest software for FEM analysis is utilized for fixture designs to produce the best results for fixtures with an exceptional dynamic performance.

  • Guided Head Expander with Lifting System
    The guided head expander with lifting system option allows the operator to raise and lower the large head expander with ease and safety. It helps the operator to increase productivity as the head expander is precisely aligned with the shaker armature. It do away with hoisting facility to remove the head expander and space to place the head expander when rotating the shaker to the horizontal slip table.
