I wondered if it's for pulling a telephone line or power cable up to the crossbar on top of a pole. Possibly, with the long chain attached to the cable in the ground, the linesman braced the squared edge of the winch against the crossbar and hauled the heavy cable up. The ratchet allows him to gather breath!
If a lineman's tool, it dates back to men doing everything with ladders. The chaps repairing overhead power cables in the village recently used a cherry picker.

I am an overhead linesman, we still use spikes and ladders if needs be!
Overhead power cables are under a lot of tension and require the use of winches, rated pull lifts and strops due to achieve the required tension. The minimum rated pull lifts we use are 0.5T off the top of my head, used for low voltage cables.
