The Class H system is built to handle demanding workloads, especially when labs test large quantities of high-hardness metals such as alloy steels, heat-treated components or structural materials. The dual-column frame provides strong lateral stability, which prevents the structure from flexing during high-energy impacts. Combined with a heavy cast iron base, the machine absorbs each strike without shifting, even during long test cycles.

The servo-motor lift speeds up workflow by raising the pendulum quickly and consistently to the preset angle. Because the operator does not manually lift the pendulum, productivity remains high throughout the shift and operator fatigue is reduced. The automatic return after impact allows the next specimen to be loaded almost immediately, which is ideal for labs running dozens or hundreds of samples per day.

The fully enclosed testing area and electromagnetic lock keep operation safe during fast-paced testing. The machine’s precision bearings, rigid frame and consistent release mechanism maintain accuracy even when repeatedly striking high-strength materials that generate strong vibrations. This combination of strength, speed and stability makes the Class H a suitable choice for intensive, high-hardness material testing.
