Mobile system for metering and classifying load cycles for support structures esp. bridges

摘要

The metering system has a load cycle integrating unit (1) and includes a mechanical strain intensifier (3), a digitalising element (4) and a current supply unit (6). The load cycle integrating unit is accommodated in a water tight metal protective housing having small dimensions. The measuring unit (2) is arranged at the fixing wall (7) of the integrating unit. The measuring unit contains the mechanical strain intensifier, which consists of a body, the both ends (8,8') of which have a much larger nearly strain resistant cross section, than the well narrowed more elastic centre part (9), provided with a strain gauge (10).
