Testing device for weight-loaded examination of materials used in e.g. drilling machine, has support portion that is vertically moved on surface of frame by operation of linear motor, such that test element is vertically moved
The testing device has a test element (5) which is arranged at the bottom portion of a movable support portion (7). The support portion is vertically moved on the surface of a frame (2) by the operation of a linear motor (9), such that the test element is vertically moved for performing the testing process.
