Hand truck jack helps lift items and stays in place. It will lift a few items I've tried, but that's only if the edge of the jack can hold or grab the ground. It would be nice if the rim of the jack was larger to better hold and lift items. I've tried lifting it on several items around my house and the problem with some is that the lip isn't big enough to grab the floor and lift it. If the item can stay on the lip, he picks it up. The jack also doesn't have a controlled release, so you'll have to be careful when resetting things. Also, one of my jacks has handles, the black foam was torn when it arrived, a little worried about this because I bought a new item and mine had a tear on the foam handle. These hand lifters are good for some items to help with lifting. I wouldn't necessarily buy these bushings again as the protrusion is too small and letting go only causes the item to fall right back to the ground.
