Retrofit works:

Improve the stability and test accuracy of the original 4000-ton multi-functional testing machine.
the joint control with the 6000-ton test machine to upgrade the existing 4000-ton multi-function loader (test machine) controller:

• Improving the stability and test accuracy of the original 4000-ton multi-functional testing machine.
• Controller and hydraulic hardware upgrade
• Controller upgrade to include control over another 6000-ton testing machine

Main Specifications:

• The upgraded 4-channel controller improves the force and displacement control over existing 40,000kN vertical actuator, 4,000kN horizontal actuator, and the two 2,000kN vertical actuators on both sides of the system.
• A digital communication interface with the 60,000kN controller to simultaneously control both testing machines.
• Control of crossbeam lifting console is upgraded to touch screen.

Retrofit works:

The original 2000-ton long-column press was retrofitted to perform force and displacement control in accordance with internationally standard test methods. The retrofitted machine was also able to complete stress-strain test of confined concrete at low and high strain rates.

New hardware such as controller, displacement sensors, hydraulic pressure sensors, etc were provided.

Main Functions:

• Tunnel ring segment reliability testing

Main Specifications:

• Five actuators of 2,000kN each acting in the vertical direction (Y-axis)
• Five actuators of 2,000kN each acting in the horizontal direction (X-axis)
• Two actuators acting in the Z-direction providing boundary condition for the tunnel ring segment
• System is designed for short tunnel segment made up of 5 ring segments of diamater 7.6m, and width 1.6m each.
  (System can be customized according to test requirement)
• System is designed for testing based on three different scenarios.
