Sorry I didn’t take any photos of the lift mechanism. I will look for a brand name and see if I can find more out about the bed. I do know it uses linear actuators, kind of a scissor design with 2 actuators, one pushing each direction. Rated to lift 500 lbs so I figure it should be good for 750… Me and another guy stood on it after the steel top was on and it lifted us, he weighs 220 and I weigh…..well let’s just say more than that and the top weighs about 140. Once it drops all the way down it is setting on 4 swivel casters so it moves real easy. All I really did was remove the mattress, side rails and a couple safety covers and then set the top on it. It’s not fastened, just setting on there. Seems very stable, raises from about 6” to 38”.
Took longer to get the shop “camera ready” than it did to build the table….lol
Oh I forgot, the top is 42" x 88"
