Stop in for a cup of coffee

Im not sure the type of anchors your using for your lift, but I highly recommend these!

The anchors that your use a set tool to lock in place can pull out and not really "grip" the concrete.

We use this style at work all the time and they bite and hold! Only down side to them is your told if you ever remove them you have to drill a new hole or use a chemical anchor in the hole to rehold them.
