The steelyard is a Chinese invention.

the steelyard consisted of the following parts: an arm, a hook, lifting cords and a weigh. The arm or beam measured about 1.5 metres long, graduated with the weight units-jin and liang. The hook, hanging from one end of the arm, was used to lift up the object to be weighed. Hanging from the other part of the arm was the free-moving weight, attached on a looped string. On the arm was fixed one, two or three lifting cords, placed much closer to the hook than to the other end. Anything to be weighed should be picked up by the hook.while the weigher lifted up the whole steelyard, holding one of the cords. He then slided the weight left or right until he found a perfect balance of the beam. He then read the weight from the graduation mark on which the weight-string rested.

This kind of steelyards is still in widespread use at market gatherings in China.
