A smart, communication-enabled vertical-load module that applies a purely gravitational load to an experimental structure and measures the resulting weight force with its built-in load cell. The hanger attaches to a node disc or a load support via the click system and is identified automatically by the Sangari software. Three
20 N weights stack on the hanger to vary the load in discrete steps, and the reading is shown on the local OLED as well as in the software. Used with truss, bridge and beam experiments on the
ST500 frame.
