We've got an older house with floors that dance a little too much for my comfort. Today, we're showing you the Ellis Manufacturing Light Duty Lifting Shores, showing you how we installed them, and hoping that if we made ANY mistakes, that someone will comment! These joist jacks are made for permanent installation, so hopefully we made the right call for our floor joist support system
Joist jacks and screw jacks come in a lot of configurations, but I felt that these were the best choice because they are steel and we have somewhat damp conditions in the cellar. they are also rated for permanent installation. Have you used these before? Let me know what your experience was!
Here's the info from Elllis Manufacturing:

The Ellis Light Duty Steel Lifting Shore is a patented adjustable structural support system incorporating a thrust bearing to reduce turning effort under load by 90%. These lifting shores can be used in temporary or permanent installations and offer safe load ratings up to 20,000 lbs. They are frequently used for additional support in crawl spaces and attics, and are also excellent for support under floors, ceilings, decks or staircases, as well as beams and slabs of wood, metal or concrete. Support under: floors, ceilings, decks, staircases, wood, steel, concrete beams and slabs.
All Ellis Light Duty Steel Lifting Shores now come with the 4 lug lifting nut. Used the 3/4" Diameter Steel Adjustment Rod to lift loads up to 20,000 lbs.
The patented Ellis Thrust Bearings on the Light Duty Lifting Shores enable these shores to lift up to 10x the amount of load compared to the Light Duty Steel Shores (w/o bearings). Adjustable structural support column for temporary or permanent support with a patented nut housing tiny thrust bearings to allow for easier adjustment under load and jacking weight with significantly less force. Add any length 3/4" Diameter Steel Adjustment Rod for extra leverage and lift up to 20,000 lbs.
In the product animation below you will notice the thrust bearings inside the nut. The bearings greatly reduce the amount of friction when the Steel Shore with Roller Bearings - house jack handle is turned to adjust the height under load.
Unlike the Standard Steel Shore, these with Roller Bearings are built as one complete unit to aid in uplift resistance and do not come apart. Furthermore, we've added a "set screw" in the side of the nut, and when tightened down locks the adjustment handle in place for permanent or long term shoring applications.
The 6" x 6" top plate is attached with a clevis pin and interchangeable with different shapes and sizes. Click here to see a few of the different tops to choose from: STEEL SHORE TOPS.
*All Load Capacities include a 2.5 to 1 Factor of Safety.
