DIY Portable Gantry Crane

In this video I am building a small Gantry Crane for lifting a 1941 Monarch 14Cx30 Lathe.  The Lathe weighs around 4000 to 4500 pounds and I wanted something that would fit in my garage, fit in the garage it's currently in, and yet had wheels so I could move the gantry crane.  Most of the Harbor Freight / Northern Tool options end at 2 Tons.  So I used some online engineering calculators to determine the minimum build strength and then bought available materials that exceeded that.  Main beam is a W6x12 with an 76" span.  I am using Harbor Freight Long Ram Hydraulic Cylinders rated at 3T ea for doing the lifting on each side.
