I guess I'm more confused than usual. Not understanding what you are pushing on that would be raising the frame or why. I thought you were just raising the load arm high enough to swing the stirrup into position. The purpose of the chain around the jack is to keep the frame from raising in relation to the load arm.

If the frame is raising and there is nothing to do to prevent it then the anchors in the floor and a chain around the frame might be an option -- as long as you still use the chain around the jack while raising the arm. I would not trust anchors alone to keep everything on the floor with the massive force that arm has stored up.
