N-K Supporto da appendere alla porta della cucina, porta Outlet Sale Online N-K Supporto da appendere alla porta della cucina, porta Charlotte Mall Great price and just what I needed. Raising the floor.(I am a licensed professional engineer).The product must be installed vertical within 1 degree. Why? because the adjustment screw plate's contact with the metal cylinder is only 2mm. The mounting plates are sheet metal - not plate. They immediately deform under minimal loading (less than 1,000 lbs.). Once deformed, all the weight is on the 10mm x 6mm pivot point on which the plate sits. Therefore, deformed or not, the plates have zero structural value. The way the plates are manufactured - is by press stamping - so the "centering" alignment is like an inverted bowl, rather than a sharp 90 degree raised lip. This adds to the criticality factor for slippage. Then, like the cylinder, the contact depth is around 2mm. One slip under load and risk of collapse = death or serious injury if "you" happen to be in the way. I only kept these knowing the severe limitations, because I was in a bind this weekend to level a shed (combined weight less than 1 metric ton - including contents.My "fix was to completely degrease the jacks and MIG weld the screw plate to the cylinder and likewise the top and bottom plates to the top of the screw and the bottom of the cylinder. Once I pour my beam footings and they set-up in a couple of weeks, I'll remove these jacks and throw in the trash.Screw and nut are good, tube is ok. The issue is the top and bottom plates are thin, wimpy, they distort and collapse under pressure.We made new plates for the screw side from 1/4 inch steel plate. Simply drill a 5/8 hole into plate. Then they work without distorting and crushing of the stamped steel bubble.We also used a moly grease to lube threads and top plate screw hole. We were able to shore up the house using a large adjustable wrench and a pipe for leverage. For the kind of lifting force you likely need, this might be a problem, then if an inspector sees a crushed plate, wont be good either. Adding more jacks closer together will help lessen the load on any one jack. We used 2x10 xXX wood boards tripled up for new girders. So these jacks sit on concrete block bases and push on new girders to hold up sagging 2x10 floor joists.These floor jacks can carry a full 18,000 lb load as long as they are not extended past 15 inches high. You can get another 3" but they will not carry full weight. Might be ok for lifting a sagging floor, but you need the full capacity if there is a wall above your lifting point.The comments about the flimsy base plates are correct. At anything like full load, the plate into which the screw fits collapses until it touches the surface it is lifting. This can be easily stopped by placing 2 each 1/2 in. washers in the dimple so that they carry the weight instead of the plate. When the load compresses the plate, the washers hit first. If the washers dig into the beam a bit, then the load spreads out to the rest of the plate. Works fine, and requires no machining.The fact that the parts are not welded together does make it hard to assemble this jack in tight spaces. I found that I could hold things together with masking tape long enough to get everything in place. Once there is even a slight load, everything stays where it belongs just fine.Be sure to wipe off the screw and nut and make sure the threads run smoothly before you try to use this jack. There was dirt and metal filings on mine that tended to jam the screw. Be sure the tip of the screw which carries the load is clean and smooth. I had to remove some burrs and dirt to get a smooth bearing surface. After everything is clean and turning smoothly, grease the threads and the bearing surface. Otherwise it will be very hard to lift anything close to the rated load.So, a little more care at the factory, and a proper top plate, and this would be an excellent product. It could be further improved by providing a second set of flats for the wrench at 90 degrees to the first set. With only one set, in tight places, you have to use a small pipe wrench to turn the jack screw.I've been buying other jacks that come all welded together, I guess at this price point you don't get that. I didn't feel safe temporarily holding up my house while I replaced a couple posts underneath. I ended up welding them together so I don't have to have 4 hands to set it up and pray that it does not get knocked and fall apart. Once I welded it all up, they function fine.
