Wing rigging tools 4.

A very useful tool, a pump jack that has front castering wheels.
Capacity is 1,250 lbs.
My Dad's friend at East Meadow Business Machines was retiring ~2000 and gave this to us. He used to use it in the 1950s to work on huge bank teller machines that weighed 500 lbs. plus. We cleaned up and painted ~2000 and rebuilt the hydraulics the beginning of 2010, (no more leaks, or slow leaking down). Amazing but doing an Internet search found that the company Star is still doing business under Star Hydraulics and had a rebuild kit in stock!
We used this to hold incidence angle when bonding in lift pin sockets.
