HUT-D Series (600kN-2000kN)

The utilizes a top-mounted actuator design, enabling a dual-acting differential cylinder to perform both tensile and compression tests within a single test space. A zero-backlash load frame and an actuator with adjustable vertical positioning provide flexible test-space configuration and ensure long-term stability under demanding testing conditions. Primarily designed for tensile testing of metallic materials, the HUT-D series supports force, displacement, and strain closed-loop control, with seamless transitions between control modes. Test results are automatically calculated by the software and can be printed or exported in multiple formats.

Applications

Rebar, welded components, castings, fasteners, chains, etc.

Standards

ISO 7500-1, ISO 9513, ISO6892, ISO 15630, ISO 15835, BS 4449, ASTM E8, ASTM E 83, ASTM E4, ASTM A370, ASTM A416

Features

Energy-Efficient and Eco-Friendly Design

Compared with the previous generation, the new HUT-D Series delivers significant performance improvements:

15% reduction in noise
74% reduction in power consumption during testing
8%-29% reduction in footprint, depending on model size

High-Stiffness Load Frame

Frame stiffness has been increased by 120%-188% compared with the previous generation. This improves measurement accuracy and reduces machine vibration during testing.

High Speed, High Efficiency, and Easy Operation

Upgraded hydraulic power unit and optimized piping design increase no-load running speed and overall testing efficiency. Optional integrated touchscreen PC provides intuitive machine control and quick test setup.

Smart Visual Interaction System

An intelligent four-color status indicator (compliant with IEC 60073) provides clear visual feedback on machine status. This intuitive signaling system helps operators avoid improper actions and enhances overall operational safety and efficiency.

Intelligent Handset Controller

The new Handset V3.0 features a 3.5-inch high-resolution touchscreen, displaying real-time load, crosshead position, machine status, and grip status. The touchscreen interface allows users to enable the servo system directly.

The jog wheel enables servo activation and supports quick language switching. Dedicated function keys provide grip open/close control and allow rapid return to a preset initial position.
