Wing rigging tools 5.

Another very useful tool.
This pump jack has a 750lb. capacity.
Instead of having casters in front, it has a work plate that will lay flat on ground! Our other pump jack has the work plate probably 6" off ground when in the fully down position.
I purchased this tool from Grainger in 1987, we just rebuilt hydraulics the beginning of 2010, (no slow leaking down anymore).
Again we used this to set angle of incidence when bonding in lift pin sockets.
