A gallows (or less precisely scaffold) is a frame or elevated beam, typically wooden, from which objects can be suspended or "weighed". Gallows were thus widely used to suspend public weighing scales for large and heavy objects such as sacks of grain or minerals, usually positioned in markets or toll gates.
