This is a hot galvanized sliding shackle. It is used on pipe tracks for pigs or sheep.
Construction:
The over side of the carriage (the sliding stirrup) is made of flat bar and round bar. The curved upper side touches to the track. The hot galvanized surface well slides, so the sliding shackle is very suitable also for manually and conveyorized moving. The hanged up hog can be elevated to the track by the bleeding elevator. The elevator hooks up and elevate the shackle by a "horn" on the stirrup. The shackling must happen after stunning. The removing of shackle is before scalding.
