Introduction
The host uses four column frame structure, composed of a base, actuator, column, can guarantee the special hydraulic chuck, tension compression fatigue test, high precision load sensor etc.. (beam using the full hydraulic lifting, way down, so as to adjust the space, at the same time, easy to calibrate, beam with tight function, hydraulic lock easy positioning, reliable locking, convenient operation.) The beam position in the range of 50 ~ 600mm adjustable.
Frame structure with four columns and columns in the middle of the host structure, frame structure, in the two column is arranged in the middle of a horizontal tensioning device.
