| Feature |
* Actualizing servo controlled pulse motor made possible to do both Static & Dynamic tests with only one actuator. Pulse motor servo can perform without hydraulic pump though general hydraulic servo system needs it, and it actualizes compact design & reasonable system. Besides, it can do stable loading than pneumatic servo on Static test, and it has no noise on Dynamic test.
* Simple operation & maintenance because of simple structure with pulse motor. It works without hydraulic pump and large capacity compressor.
We delivered DTC-492 to Japanese customer.
It is only domestic sale now, so please wait for a while.
