For sale is a CAS NC-1 1,000 1000 lbs capacity CRANE HOIST BALANCE BEAM SCALE. It needs a wall wart type charger, which I do not have. I charged it from a 12v power supply to test it. After charging, it would power on, display a number, and if I load it, would display a weight commensurate with load. I did not perform calibration, but it looks like a working scale to me. Charger not included, but I think that a wall wart from Wal-Mart would work as long as it has the proper size.
