Horizontal plate lifting clamp

Post by GEON »

I just put an adjustable gantry crane system in to move steel onto the table and then realized I would need to get some clamps. I had some small pieces of 1/2" in the shop so I decided to make my own.
My crane can handle 1000lbs so that was my design target. I don't/can't/won't warranty that this design will handle that -- but everything is spec'd to be on the beefy side. I modeled the design on many I had seen on the web that are similar.

I used 1/2" for all the parts. I welded the small piece between the cheek plates. This makes the underside of the clamp one solid component...

I was very pleased how cleanly the 1/2" steel cut on the table:

Here are various pictures of the clamp as built:

As attached to the gantry:

The DXF files are in 3 components - the side cheeks, the clamp arm ad the small anvil that I welded in. I used a 1/2" grade 8 bolt to hold it together.

Again - if you are worried about load limits and want to rant on this - please don't, just don't build this. If you find it useful and it will save you 120$/clamp - great!

Here are the DXF Files

Crikey - the site isn't letting me add the other files. Let me know if you are interested...

I have not built my lift yet. When I do I will be back for the files. THank you so much, I was wondering how I was going to create those.
These look perfect, I will scale them down a bit as I only cut up to 1/4 inch.

I have a set made from 3/16 plate that I've lifted half sheets of 3/4 with so I'm going to say your design is more than capable! :-)
