The three-degree-of-freedom loader can apply a pure vertical (Z direction) 100kN, pure horizontal (X direction) 50kN load and a pure twisting torque of about 20kNm or 2kNm dynamic torque around the Y axis. Either a single load can be applied alone, or any combination of the above two degrees of freedom or a composite synchronous or asynchronous load of three degrees of freedom can be applied.
