The weight I plan to lift with my forks shouldn't exceed 1200 pounds.
The welding table I made a couple years ago. The design has the hydraulic cylinder pushing the front lift arms and the top deck frame frame pulls the rear arms along with it. Once at desired height, lower the cylinder with the safety stop locking into position holding the rear lift arms and the cylinder holding the front lift arms. It's absolutely solid as a rock.
The frame is 2"x2"x1/4 angle top and bottom. The lift arms are 2"x2"x1/4" square tubing. I used 5/8" grade 8 pivot bolts top and bottom. I designed my table long enough to hold my motorcycle @ 8' long and 33" wide. The top platform drops to 10" off the floor with a max height of about 33". My ramp connects to end with the vice and I drive up the ramp with my motorcyle. I do have to remove the vice and mount the wheel chock to anchor the front tire. I'll get some more pictures of it. It's pretty simple to make.
