I have two different ideas that you could consider.

1. Use a hydraulic lifting cart. I have a Harbor Freight 1000# capacity cart that I use to move and lift my two sons that have special needs. (https://www.harborfreight.com/1000-lbs-capacity-hydraulic-table-cart-60438.html?_br_psugg_q=hydraulic+lift+table) Their website lists it for $280, I was able to use the 20% off coupon to get it. It has a 24” total lift, a bit less than your 30” with the scissor lift but not far off. You could build your platform on top of it to get the height you need. The lift is 180 pounds and bottom heavy. The top of the blue pad is 12 1/4” off the ground at the lowest setting and 36 1/4” at the max lift. Here are pictures of what I built:

2. The second idea may be out of left field but could work. You could make the entire wood rack raise and lower using an electric hoist. I had thought of using something like this for an adjustable height wood rack: (https://youtu.be/CgdsamzPN8w). I decided against it for a wood rack but just built one to put my CNC on since I’m very short of floor space.


The hoist I bought has an 880 pound capacity when using the included snatch block. Between the table frame, torsion box and CNC machine it is approximately 300 pounds being lifted and center of mass about 2 feet from the unistrut. It’s built with the intent of carrying the weight in the ceiling joists, the studs behind the track and through the track into the ground. A couple of points I think are important:
-I don’t intent to leave it stored in the raised position when I’m not in the shop.
-When it is in the raised position I will place four 500 pound capacity straps from the the hoist’s unistrut to the table frame and from a ceiling joist to the frame. I don’t intend for the hoist to continuously hold it in the up position and will not walk under it until those straps are safely in place.
-I am also working on a way to use beams from the floor to the frame as a safety device when in the raised position.

For a wood rack I think it would be better to increase the space between the tracks to 80 or 96”. Mine is at 32” spacing which works since the table is 46” wide.
