If you own a Hi-Lift jack, you’ve probably dealt or struggled with the issue of how to lock the handle firmly in place during transport.
The spring clip that comes on the jack is worthless (and not designed) for that purpose. The polyurethane collars that slip over the handle and shaft are okay, but in my experience they stick when new, and eventually wear and slip down on the jack if it’s stored upright, or vibrate right off the end if it’s stored horizontally. For a time I just used a piece of One-wrap (hook-and-loop tape), but I’m not a big Velcro fan, and it quickly clogs with dirt when used in such an application.
A few years ago I set out to make something better. With an old sheet of half-inch-thick HDPE plastic—I don’t even remember what from, perhaps a cutting board?—I started playing around with ideas, and eventually came up with what you see here.
It slips easily over the shaft and handle of a Hi-Lift, and you can lock it anywhere you like with the two through-pieces and then the spring clip. It can’t slip. The only disadvantages I’ve found are that it won’t slide over the removable clamping foot if you keep one attached (although you could modify the opening so it could), and it has multiple pieces that might be prone to loss. However, I think it would be easy to modify it with a safety wire that would keep all three plastic bits together.
Always remember to store your Hi-Lift with the operating lever in the “lift” position.
P.S. If you don’t want to make your own, Step22 Gear has a promising alternative, here. I just got one and will be reviewing it soon.
