The frame is built to handle sustained, high-force testing on large cross-section metal specimens, as long as the machine is sized and configured for your load level and specimen geometry. In the NG-SHM Series A, the multi-column high-stiffness frame is intended to minimize deflection under heavy loads, and the hydraulic power unit includes active cooling to support continuous operation.
For large cross-section work, the practical limit is usually not just the frame, it is the full load train. That includes the selected force capacity, available test space, and the grip or compression fixture package. This series is offered in multiple force capacities, and the listed specimen size ranges vary by model, so the right match depends on what you are pulling or compressing and how long you need to hold near peak load.
If your method includes long holds, proof loads, or repeated high-load cycles, it is worth confirming the exact configuration, including grips, platens, and cooling and hydraulic power unit sizing, against your duty cycle and specimen dimensions.
