Smart line-load module for distributed loading of bridges and beams on the ST500 frame

Three instrumented line-load elements that clip onto the roadway of a bridge or beam experiment to apply a distributed load over a finite span. Each element reports its position along the roadway - encoded as a 4-bit Gray code - and its applied force to the ST500 host software. Multiple line loads can be placed end-to-end, or combined with ST505 point loads, to vary the loading pattern and study support-force response and bending behaviour as a function of load distribution.
