the chinese used winches for large crossbows mounted on fortifications or wagons, known as "bedded crossbows" . winches may have been used for handheld crossbows during the han dynasty, but there is only one known depiction of it. the wujing zongyao mentions types of crossbows using winch mechanisms, but it is not known if these were actually handheld crossbows or mounted crossbows. another drawing method involved the shooters sitting on the ground, and using the combined strength of leg, waist, back and arm muscles to help span much heavier crossbows, which were aptly called "waist-spun crossbows" . 打印准备: 否
