Some test objects are not uniform and require eccentric or overhanging loading. In X and Y axis, the Horizontal Slip Table constraints the Armature of the shaker in one direction using bearings, but in Z axis, the same is not true for the Head Expander. A Head Expander is not supported by the shaker and there is a limit to how much working area you can increase using it for a given Armature size. For these non-uniform test objects, a Vertical Load Support (VLS) is provided which is a guided Head Expander. This attachment is supported by linear or hydrostatic bearings attached to the body of the best replica watches shaker. The bearings constrain the motion of the VLS to Z axis only. Air bellows are provided for further support, if required. A Vertical Load Support can be designed in a square or rectangular shape based on the customer requirement.
