ABSTRACT:
A device for counting and classifying load cycles in supporting structures with various loads, bridges, cranes, or tracks for example. A measuring instrument (2) is attached to an attachment side (7) of a load-cycle counter (1) and accommodates a mechanical strain amplifier (3). The ends (8 & 8') of the strain amplifier are much thicker and more resistant to strain. Its middle (9), which includes a strain gauge 10, is much thinner and more sensitive to strain. The ends are fastened to the attachment side. Any signal deriving from traction, force, or flection, and emitted by the strain amplifier (3) is forwarded through a digitalizer (4). The data are processed and stored in a signal processor (5).
