Head Expanders

A Shaker, in vertical orientation, operates in the Z axis. The diameter of the Shaker’s Armature is limited by the rating and design of the Shaker. Many times, dimensions of the object exceed the working area offered by an Armature. In order to increase the working area of an Armature, a Head Expander is used. We offer a complete range of Non-Guided and Guided Head Expanders, in circular and square shape, to meet requirements like testing large objects to testing multiple objects at the same time. Our Head Expanders are manufactured by welding magnesium alloy tool plates and are treated with vibration dampening material to reduce peaks and harmonics. Guidance comprises of air bellow for increasing the effective payload capacity along with self-aligning bearing assembly for less eccentricity payload or rocker assembly for high eccentricity payload. They are available in various shapes and sizes with customised hole patterns as per customer requirement.
