HUT-A dual space wedge action grip

Description Applications Contact us

Load Frame Configuration: 4 or 6 column, servo-controlled hydraulic

Capacity: 200kN, 300kN, 500kN, 600kN, 1000kN, 2000kN

Test Space: Dual zone (tension on top, compression on bottom)

Typical specimens: Fasteners, rebar, chain, welds, castings

Frame

1. Lead screw driven crosshead to adjust the 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
