It is powered by a winch and belting. There are several discreet loops of surgical tubing on each side, so one break doesn't unwind the whole bunch. And, yes, the load cell is there to make up for discrepancies in tubing, belt stretch, etc.
And surgical tubing has been very good to us. We are sponsored by a medical plastics manufacturer...
