Emergency jack retracting totter

I made this after spending a small fortune replacing a solenoid valve that overheated. I plan to use it during emergencies and during very cold weather. 48" long, 12" half circle centered, under 5 pounds.

A great "jack retraction tool". You need to market that bad boy!

Great idea. Necessity is the mother of invention.

I've found that a once a year process of extend jacks, wipe down w/rag wetted w/trans fluid, wipe down w/dry rag keeps my jacks retracting well. But for some silly reason, my FL jack occasionally gets slow. One of these gizzies would be efficient for take-off in those cases.

Very Good. I wind up lying on the ground with a 2X4 and shoving it under the jack foot then lifting. I like your idea but I need to make the end for the jack foot to be ab le to fit under the foot when there is only approx 1 inch between the foot and ground/cement. Thanks for the tip. I will plagerize your idea for my own benefit.

This is why I made both ends different heights, you might want to make one end without additional plywood and cut the top plywood short about 8". This would bring it down to 3/4" + the angle. Glad everyone likes the idea. Its really easy to use and to store.

the jacks of my rv are only about 2 inches above ground when retracted. Looking at the pictures here, it looks like I need to push them in - would that fix the problem? Do I have a problem?

Paul Gitter,
That looks too close to the ground to me. It's hard to tell with the pic if this is normal. If the cylinder is all the way in and the square tube is not supose to retract also and the warning light/buzzer off, it might just be the way they are. Interesting to note that we can't see any retracting springs in the pic. Are they all low like this?

Yes, the two in the back are both low.

I just looked at them again and there is a positive stop (yellow highlight) on the jacks and it seems that they are all the way retracted.

Paul & tyka. Difference between a gasser; fixed suspension; and a DP; air suspension. On the gasser to rams are mounted low so they reach the ground with the same amount of stroke. So they are tipically 4" closer to the ground, the amount of drop when the air is dumped, on a DP.

IMO you definitely have a problem. Your jacks appear to be Atwood electrics which are supposed to have 8-9" of ground clearance when up. I sure wouldn't drive the rig with only 2" of clearance, you will bottom out on them sooner or later.

I think I would make the fulcrum moveable so that you can get a better mechanical advantage at times.

Seam low to me also may want to have checked out in rear may need to be moved up on mounting holes.
I do like the jack piston lifter I have to use a 2x4 pressure treated board all the time just in case, cheaper than solenoid.
