Product number: HST8

Two portal frames (pitched and rectangular) are mounted within two “ground” supports, in either a pinned or fixed condition. A proportioning bar is held horizontally by loading chains that run to the portal frame and to the screwjack loading mechanism (with integral load cell). Depending on the position of the loading mechanism on the proportioning bar depends on the proportion of the load being applied either horizontally or vertically.

The load applied is measured using the load cell in the loading mechanism, which is fed directly into the HD200 Interface (sold separately). Two moveable dial gauges are used to monitor the deflections into the plastic range of deformation of the portal. Additional portal sets are available as an optional extra (HST8a).
