For Full-Scale Testing and Evaluating Large Samples
Jack systems are used to test strength characteristics by attaching a jack to a test oor in a strong room, to a reaction wall, to a base plate (made
of steel) or a testing frame, and then applying loads to samples in a speci ed mode. Two types of jack systems are available, either dynamic or
static, based on the test objectives.

Low-Friction Actuator
Dynamic testing jacks are designed with low friction to maximize endurance.
Supports Multi-Jack Systems

Customized multiple jack systems, to multiple jacks are linked and controlled to apply loads in any XYZ direction, are also available.
Jacks Can Also Be Installed on Cross Beam Type Testing Frames
By installing a cross beam type testing frame on a testing oor, jacks can be mounted and used as a testing machine for structural members.

Swivel Head and Swivel Base Servo Valve
Swivels joints are installed on the front and back end of the Made to special speci cations for Servopulser
actuator for use in full-amplitude tensile and compression series systems, these valves offer especially high
testing. The swivel joints, which can freely tilt vertically or responsiveness. Therefore, they provide a long

This base makes it easier to remove jacks from a reaction wall horizontally. High surface hardness and ultra- nished rod
