NG-SHM Class B – Servo Hydraulic Testing Machine

Class B

The NG-SHM Class B series is designed to provide a solution for your high-force mechanical testing of a diverse range of materials covering many different industries. Class B has been designed around the application of testing fasteners, rebar, chains, welds and castings and uses a "worm wheel" driven cross head to adjust the test space.

Force Capacity: 300kN, 600kN, 1000kN, 3000kN

Load Frame Configuration: 6 column, servo-controlled hydraulic

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

Load Frame

• Lead screw driven crosshead to adjust the test space
• Durable 6-column load frame design incorporates 3-position crosshead, adjustable specimen positioning, precision guide columns, thick crosshead and a base beam minimizes the load frames stored energy while producing reliable, stable, accurate loads, strain and modulus values.
• Ergonomically designed load frames ensure safety, reduce operator fatigue, and provide the highest level of flexibility.
• Standard Dual Zone Test Space for reducing setup time
• "Quick Return" hydraulic valve for higher throughput
• Automatic limit checking for crosshead position, overload, over temperature, over voltage, etc.
• The system can return automatically, the oil cylinder can return to the original position manually or automatically after finishing testing
• Positive specimen holding is ensured by the wedge action hydraulic operated grips
• Encoder mounted on the seat is for position measurement of the crosshead to provide higher accuracy
• Servo valve provides high stability and reliability

Load Cell

• Uses strain gauge load cell technology to measure the force being applied to your specimen. The load cell is located in the lower grip and is used to directly measure tensile force.
• Precise load cell measures and captures sensitively tension and compression force, high accuracy load measurement resolution reaches 1/350000.
• Quality load cell ensures high precision and repeatability.
