Anyone using Happijac 4800 jacks?
I need to replace one jack. It's bent just enough that it's pulling a lot of current, and sometime blows the fuse for the right side. The jack works great with a hand crank but I want all 4 to work w...

Interesting, this popped back up after 3 years. I had quit thinking about replacing the jacks. I just didn't want to waste money replacing the 4500s with another jack that probably wasn't any better, and I know the 4500s aren't strong enough for my camper.
I still haven't replaced my HJs. Didn't get a wide spread warm feeling that the 4800s were any better than the 4500s despite the corporate bragging. A second jack failed in 2016, only working when unloaded, so I've been using a hand drill and the hand crank for 2 years.
Everything I read about ACME thread jacks said they were cheaper to make, but the 4800s cost more than the ball screws and both are quite a bit more than the Riecos.(jacks only) But then I'd have to buy motors if I went with the Riecos and the weight capacity is less. It's a big investment.
It isn't that much trouble to hand crank, but it would be nice to just push a button.
If I find some on a real sale someday, which I have never seen any discounted more than $10 or $15, I may buy them.
