HUT-A Series (900kN-3000kN)

The servo-hydraulic testing machine with dual-test-space features a lower-mounted actuator and two fully independent test spaces:

Upper test space (between the upper and lower crossheads): primarily used for tensile testing.
Lower test space (between the lower crosshead and the test table): designed for compression, bending, shear, and flexural tests.

Both spaces can be configured by raising or lowering the lower crosshead through a lead-screw system, enabling flexible adjustment to accommodate different specimen sizes and test setups. This testing machine is widely used for tensile, compression, bending, shear, and flexural testing of metallic materials. With appropriate grips, it can also support a broad range of tests on various structural components.

Applications

Fasteners, rebar, chain, welds, castings
