●Bending Test System for Large Structure
This system has a four-column frame with an actuator and long base plate so that a large-scale structure can be fixed on it. It conducts a three-points bending test and four-points bending test with rigs.

●High speed Loading Test System
The purpose of this unique test system is to analyze and verify a rupture mode of structural component under an impulsive dynamic force, which used to be difficult in performance by conventional systems.
