LOG LOADING SYSTEMS

These pictures show a typical loading system used in the era of steam logging. The logs were "yarded" up to the "landing" and the loading donkey would set them onto rail cars, also known as "skeletons"

Identified are a few of the numbered items in this drawing.

5. Mainline cable to the donkey.
6. Bullblock for the mainline. Raises and lowers the logs.
7. Haulback cable to the donkey. In this illustration, the haulback line pulls the boom toward the right.
8. The tong line. Used to lift and lower the logs.
9. The squirrel line. Used to return the boom by means of a counterweight. In this illustration it pulls the boom to the left.
10. The squirrel "chunk". Usually a short log rigged so that it is suspended above the ground at all times, acting as a counter weight.
