How to Rig Barn Pulleys: Setting Up a Hayfork Pulley System

Let's Talk Rusty Iron

| July 2010

Pictured above is a sketch of a typical hayfork installation in a center drive barn.

The track (A) is suspended from the rafter peaks and a trip block (B) is installed on the track and centered over the wagon unloading area. The draft rope (C) is tied to the hay carrier (D), passes down around the lower pulley (E) and back up over the rope pulley (F). From the carrier the draft rope passes through draft pulleys (G, H and I) before being hooked to the horse’s singletree.

After the operator on the loaded wagon sets the double-harpoon fork (J) into the hay, the horse is driven forward, causing the loaded fork to be pulled straight up until it locks into the carrier.

At that time, the trip block is operated and the carrier is released to move along the track to the left.

When the fork load of hay is over the desired spot, the wagon man pulls the trip rope (K) and the hay drops into the mow, where the man with the pitchfork spreads it into position.

After the fork is emptied, the horse is backed up and the carrier is pulled back into the trip block by the rope (L) attached to its right side which passes through draft pulleys (M and N). A bag of sand (O) provides the weight for this operation.

Our barn was outfitted with the hayfork track soon after 1900. It was used to about 1950.By the time i could remember, the horse was taught to pull on command ahd then on commandturned around and came back to the starting point; where she again turned -to be in the starting position again. All without tangling the rope. Our barn was an end drive, 116 feet long, with a barn bridge. The track went the entire length of the barn. The track is still there.
