Panel loading and transporting cart

Postby Tailmaker » Tue Feb 13, 2018 11:07 pm

The question of how to pick up and move full size plywood or mdf sheets comes up occasionally and obviously there are many home made and commercial solutions around like the tilting Rockler MaterialMate cart. However, most such contraptions still require lifting to sheet onto a ledge and some are limited in terms of height adjustability. Some are just very expensive. So, I set out to design my own cart that can pick up full size 4x8 or 5x5 sheets (even 1.5" thick) from the floor by a single operator and without undue effort. I designed it to use a dual linking rod mechanism that moves the table's center of gravity from an offset position while vertical to a centered position when horizontal (for the folks who went to the Vectric user group meeting in Vegas I showed a 1:2 scale model. Right now it can be adjusted from 32" height to 38" but my next design iteration would be a larger height range .

All the tool paths were done using Aspire, based on vectors imported from 3d-CAD. Material is mostly 3/4" baltic Birch, some 2x4 studs and 1/2" construction grade plywood.

TM,
Nice project.
I really like how you joined two shorter side pieces together!

Well, I am an engineer and have invented/designed stuff all my professional career. Now I am retired but I guess I just can not let go...

Thanks Bob, if you mean the joint in the longer connecting links/rods that was not so much by desire but by necessity. I would have liked to cut the links as one part but they are 37" long and my machine can do only 34" max. So I had no choice but to join them. Actually they components look like that:

After seeing your drawing, now I REALLY like your design for the joint!

I am working on some way of marketing the design (after some further improvement/simplification). For now I have only submitted a provisional patent application. The idea would be to ship the parts in an IKEA-style flat pack at low cost and have the end user assemble it.

But I am in no position to manufacture in quantities as well as marketing and selling the end product. If somebody has a good idea for a suitable commercial outfit to partner with, please let me know (or email to "info *at* tailmaker *dot* net").

Splendid, Ger as usual! Will look for notice that you are licensing the plans and the opportunity to purchase them. Only a request that you consider from a grateful reader.
