A ‘U’ section, ‘L’ section and 'Rectangular' section cantilever are horizontally supported within a rotating clamp which fits in a substantial block attached to the HST1 Universal Frame and Stand (sold separately). The rotating clamp enables the loading and deflection planes to be set relative to the cross section axes. A protractor scale is fitted to the block and a pointer on the specimen references against this scale.
At the other end of the cantilevers is a boss onto which two dial gauges rest and through which the vertical loading is applied. The flat anvils of the dial gauges ensure a consistent flat surface during cantilever deflection. The dial gauges are mounted at right angles to each other and have full positional adjustment. For shear centre work, additional loading bars are supplied that attach into the free end of the specimens, onto which the dial gauges can be referenced. Loading is applied to the specimens using a Load hanger and calibrated weights set.
