A frame jack

Just wondering if anybody has noticed how long it takes for A frame jacks to move up or down. Or maybe it's just the type i have that has small gear teeth. Do they make different size gearing for them. As a comparison my fold down boat trailer jack is so my faster and with a lot less cranking.

different brands and models have gearing to lift different weights...

If you would rather not crank replace it with an electric model for about $100... check amazon...

That's what i was wondering do they make ones with different crank ratios? i don't mind cranking especially if it means costing me $100.00 for a electric one. Trouble is i don't know what my crank ratio is. so may not be a good idea to go out and buy another one that is the same or worse!

The thing about these jacks is if you're using a WDH, you're lifting up the weight of the tongue and rear of the truck. That's why you see ratings of 3500 & 4500 lbs when the actual tongue wt. is usually a small fraction of that. Electric is the way to go.

I dont ever recall a crank ratio spec, but certainly there are 1,000# 2,000# and up capacities. This suggests that you either crank harder or crank more turns rather then less turns for larger capacities.

Have you thought about putting a few blocks of 2x6 under your crank end to reduce the crank time?

If you have a tongue mounted battery and use a WDHitch then certainly upgrade to an electric model... $100 - $150+ well spent.

Yes i have used blocks. they do save a lot of cracking. Just seems like it takes a lot of cranks for not much up or down movement, and i ain't getting younger. Anyway thanks for your help. I'll just keep what is designed for my camper. And like you suggested keep using we use plastic legos under the wheel.

My last P/U had an electric front jack and it was nice. My new P/U has the manual crank and though it may sound strange, I find that after my shoulder surgery a few years ago, the manual crank is quite therapeutic for my shoulder with the cranking motion.

Well heck backpacker you are just the sort of fellow i need on my next camping trip to spell me when my shoulder gives out from cranking. Been giving that job to the wife, but i get that look from her that's not all that nice
