Our load cells are based upon a gaggle of pressure gauges that generate an analog sign. Our in-house developed electronics convert this into a electronic signal which could then be exhibited as a power or weight measurement.
Tower crane at the inland harbour of Trier from 1413 In contrast to contemporary cranes, medieval cranes and hoists — very similar to their counterparts in Greece and Rome[28] — were mainly effective at a vertical lift, and not utilised to move loads for a considerable length horizontally at the same time.[25] Accordingly, lifting perform was arranged with the workplace in another way than now.
