Sheer legs
Sheer legs The sheer legs that you can see next to the barn of the
Tommenmolen is a full-scale reconstruction that we made based on a copy
from the MOT collection and from images. What are they? Sheer legs are a
two-legged hoist with which you can lift heavy loads and also move them to
a limited extent. The device can be mounted and moved. For example, it has
been used since ancient times on construction sites to bring up heavy
stones. Until the early 20th century, such a device was used in shipping
and the military. Sheer legs consists of two connected legs with a pulley
at the top. A rope runs over the pulley to a windlass at the bottom, which
has two long spokes that act as a lever. By turning, you can lift a load of
several hundred kilos alone or with two without exceptional effort. The
device is kept in balance by tethered ropes. This reconstruction nicely
illustrates the principles of drive and transmission, which is the subject
of the MOT & GO exhibition you can visit in the mill....
