JetSJ-5T 5-Ton Screw Jack

I bought when they were 89.99. And that's a steal. I was very happy with price and quality. I use them to fix foundation's in Florida. Work very well

beefy

Looked for a jack that could hold up safely to some very large loads for an amateur fix to a foundation. We are lifting a very large amount of weight, and I bought 10 of these to operate as a deeply redundant system to lift and level of structure safely. They are exactly what I wanted for their ability to safely left large loads. Piston Jacks Can fail on your load, causing the structure to drop dramatically or putting incredible amounts of weight on the other Jack’s suddenly, which can cause what’s called a cascade failure. Mechanical jacks are the answer, because they cannot spontaneously fail and less the metal itself fails. However most mechanical jacks are prohibitively expensive. Can fail under load, causing the structure to drop dramatically or putting incredible amounts of weight on the other Jack’s suddenly, which can cause let’s call the cascade failure. Mechanical jacks are the answer, because they cannot spontaneously fail and less the metal itself fails. However most mechanical jacks are prohibitively expensive. These are incredibly heavy, Chinese mean, mechanical jacks. Well I would prefer to buy American made product, because I trust the steel more, or even Canadian, these turned out to be a good buy. We’re going to put them through heavy use throughout the summer, i’ll update this review if there’s any more to add. But so far we’ve been real pleased

I wish it were larger, but it works well.

Easy to use, strong and makes my camper very stable. No more shaking with wind gusts. Highly recommend.
