Cordless impact to crank trailer jacks

[Hay Dude]

My trailer has big rig landing gear. I hate them. Much prefer the ratcheting adjustable legs on previous trailers, but not heavy duty enough. Trailer weighs 8500 empty, so it’s a bear to raise
Unfortunately Kaufman did not offer hydraulic jacks :ashamed:

What I was thinking is to set the jack handle on the more cranks/easier setting and a good 1/2” drill will turn it easily. Just need a “ stub “ to fit in the handle shaft a drill will attach to

This is what my brother used, they are pretty slow.

If it’s anything like the powered camper landing gear they’re all slower than molasses. I’d rather have a weaker and faster system even if I had to take over by hand to lift it off the ball.

I uses a 3/8" rechargeable drill on my trailer leveling jacks. Worked fine. I have a Mikata 1/2" impact driver. I don't use that. Not so sure the jack mechanisms would handle the impacts so very well.

Not talking about leveling jacks, though. Talking about the landing gear on a trailer. Sort of boggles the mind no one has fabbed up a pipe that slips over the jack rod with an adapter for a drill or impact. Looks like maybe a $25 item. It could be removed and the jack handle reinstalled in case drill battery is dead.

Might find one here.

This is an adapter I made for my travel trailer in case the motor went out on the electric jack. I don't know why a person couldn't make something similar for an equipment trailer. It was made to use a 3/4" wrench, crescent wrench or cordless drill with a socket.

I bought a high torque 18 volt Bosch drill to crank my Bridgeport mill bed up and down. It worked well but the two expensive batteries didn't last very long. I think the high amperage for that much torque (for any time longer than bottoming out a lag bolt) probably fried the batteries. So it might depend on the sustainable discharge amperage on your drill vs the jack resistance. If the jack has a coarse acme thread, a finer thread should help.

Were they 4-5 ah batteries or some of the little ones that come with drills? They’re made to go on other high load tools like a grinder and circular saw so high load in a drill for 30 seconds shouldn’t hurt it.

I welded a nut that takes a 3/4 socket, on the crank handle for a scissor jack. I turn it with a socket and adapter on my cordless drill. If things get stiff I switch to an X-type lug wrench to turn it.
