Slab Jack

I saw someone pull up alongside a bundle, cut the ties, lay some slabs on the ground, and then back up closely to the bundle.  Intrigued, I asked about how he intended to load the bundle and he was kind enough to explain and allowed me to take pictures.  He has a beam running across the truck for support, and he can lift a couple slabs at a time.  He intends to use an electric winch in the near future.  It took him quite a while to load the bundle, but without his slab jack he would not have been able to do this at all.
