A special type of headframe is known as the hammer head tower . The characteristic shape with a slim base and protruding head, in which the hoisting machines are located, gave the hammer head towers their name.
In contrast to the previously used headframes ( Tomson-Bock , Englischer Bock), hammer head towers were built in closed construction from around 1915 . Only a few of the originally numerous hammer head towers have survived today as industrial monuments .
