Load frame
1. Worm-wheel driven crosshead ensures high accuracy movement to adjust test space
2. High-Stiffness 6-column load frame design incorporates 3-position crosshead, adjustable specimen positioning, precision guide columns, thick crosshead and base beam minimizes load frame stored energy while producing reliable, stable, accurate load, strain and modulus values.
3. Ergonomically designed load frames ensure safety, reduce operator fatigue, and provide the highest level of flexibility.
4. Standard Dual Zone Test Space for reducing setup time
5. "Quick Return" hydraulic valve for higher throughput
6. Automatic limit checking for crosshead position, overload, over temperature, over voltage, etc.
7. The system can return automatically, the oil cylinder can return the original position via manual or automatically after finishing testing
8. Positive specimen holding is ensured by the wedge action of hydraulic operated grips
9. Imported encoder mounted on the seat is for position measurement of crosshead with high accuracy
10. Imported servo valve provides high stability and reliability

Load cell
• Use strain gauge load cell technology to measure the force being applied to specimen. The load cell is located in the lower grip and is used to directly measure tensile force. 
• High precise load cell measures and captures sensitively tension and compression force.
• USA Interface load cell ensures high precision and repeatability.Rubber mat
Moulded rubber matter is easy to clean and greatly prevent machine from dust and scraps.
Integrated hydraulic power unit
• Integrated IPC enables convenient operation, and space saving.
• Japanese NACHI pump provides with low noise less than 70db.
• Wind cooling system can work automatically when reaching preset oil temperature.
• Over-pressure protection offers high safety.
• Three level filtering system improves service life.
