Gantry crane build Caterpillar D2 project extra

In this video I’m building a gantry crane that I need to take my D2 Caterpillar apart for rebuild. It needs to be adjustable in height so I can use it both inside and outside my shop, get it through the door and still have a good lift height.

I think that’s great your son was involved too. Good job! Very creative.

Don't forget weep holes for any blind pockets so the water doesn't get in it and freeze. It will crack the steel if enough accumulates. Nice project.

When I built my engine lift many moons ago I combined schedule 40 and 80 for a slip fit. I also had all the pieces hot dipped galvanized as it lived outdoors and that made the fit just right. I was using 2 inch and 2 and a half or three as I recall. The upright receiver I had to weld up as nothing was right for it. Used it for close to thirty years. A little cutting oil on those annular cutters extends their life immeasurably as with the chop saw.

grease points on uprights would help with moving up and down.

6:20 Least you could do is use some gear lube as a cutting oil. Those hollow core drills are not cheap, and sure work better when not overheated and turned to dull nubs. Oh and you speed it up... nice. Next.

You're absolutely right. Was my first time using one of these... It was an expensive lesson.
