I can easily correct all of this for this season, but really want to avoid it in the future. The dock guy (who will fix it for me) recommends a bubbler. I'm not so sure that a bubbler will work so close to the shore and with only a foot or less of water at the water's edge.
My thought is to place stones/rocks around the pad so that it becomes more "on shore" than in the water. Question for everyone, will this work? If your answer will change any, let me also say that I think the damage occured when the water level rose and nearly covered the cement pad.

While a bubbler or similar preventative measure would probably work, I thought the purpose of a crank-up was eliminate the need for such devices. What does the "pad" sit on, is it rocky or sandy or ?? If it's not rocky then perhaps you could drive something like stakes around the perimeter of the pad to corral it so that any shifting is minimal. Has this happened often or was the old rickety dock immune to small shifts in the pad's position ? Could you add some depth adjustment to the dock's legs so that when you crank it down, the legs could be extended or retracted to the needed length ? Do the legs meet up with subsurface pads or just rest on the lake bottom ?
