Remarks

1) Both nonlinearity and hysteresis are the calibrated values.
　Depends on the load surface and the load direction, they may exceed the spec. value.
2) When installing, never apply eccentricity load on it.
3) The specifications are the values under uniform load on the load surface.

As for 1.5 MN and others, please contact us.

As for existed anchors, the collaborative items Tensile Jigs and Jacks are required.
