This 8,000 lb.capacity jack works just fine when all components are secure but be aware that on mine, the lower of the two large ratcheting anchor studs had the small spring keeper pin come loose and fall out. The lack of spring action means the jack is now stuck in place and non-functional. The small pin has a tamped-in, friction fit with a swaged (stamped raised grooves) center section but either the swaged edges are not high enough or the hole it fits into is slightly too large but it can work itself loose after several uses. Perhaps mine was a one-off manufacturing error. I did reuse it but applied high strength red sleeve locker to hopefully keep it in place. Otherwise, it is a fine jack - just remember to check the position of the spring retention pins before use.

Ended up returning, tried to use it to pull posts out of the ground, and the main beam started bending. I'm only 165 and didn't have my full body weight on the the handle. I was able to bend the beam by just standing on it and bouncing a little bit. Also the jack wouldn't go down under any type of load, even a few pounds would cause the release mechanism to bind, and I would have to tap the top of it lightly with a hammer with every click down.

It's a nice heavy jack did what it was made for

Best dam thing i ever bought
