The NG-SHM Class C – Servo Hydraulic Testing Machine uses wedge-action, hydraulically operated grips to hold specimens firmly in place during testing. This mechanism allows for positive specimen holding, even under high loading conditions.

The wedge action tightens the grip as the applied force increases. As tension is applied to the specimen, the gripping force automatically strengthens, preventing slippage. This self-reinforcing design guarantees specimen security throughout the test.

Hydraulic operation adds further reliability by applying consistent and controlled pressure to the grips. This allows for fast, repeatable clamping of different specimen types, such as wires, rods, or flat samples. Secure holding is essential for accurate and valid test results, and these grips are designed specifically to provide that level of stability in both tension and compression modes.

Both models of the NG-SHM Class C – Servo Hydraulic Testing Machine, the SHM605 and SHM106, have a power consumption rating of 6 kilowatts (kW). This value represents the maximum electrical power required for the system during operation.

6 kW power consumption included the hydraulic power unit, control electronics, and servo systems. It reflects the energy needed to drive the actuator, operate the grips, and maintain stable testing conditions throughout each cycle.

This level of power usage is typical for high-capacity servo-hydraulic testing machines and should be considered when planning electrical requirements in a laboratory or industrial setting. A stable power supply is important to guarantee consistent machine performance and avoid interruptions during high-force testing.
