For a rugged and durable piece of hardware in the Ellis line, none get it done like the Ellis Bridge Jack. With top and bottom plates measuring 1/2" x 9" x 9" for support, the Acme Screw is 2 and a 1/2" in diameter and greased for easy turning and capable of extending a full 6" or 12".  For extra leverage, a 1" steel rod can also be used when turning the screw. The Ellis Bridge Jacks while weighing 60lbs (BJ-6) and 70lbs (BJ-12) can support loads up to 80,000 lbs.  The top plate has been attached to swivel freely, allowing the screw to be turned with ease. For added support, gussets on the top and the bottom plate have been added with full length welds.
 
We tested both of the Bridge Jacks to over 200,000 lbs. before failure occurred!  Pictured right is the BJ-6 inside the testing lab.

Although the Bridge Jacks were tested to over 200,000 lbs., we recommend applying a 2.5 to 1 safety factor when gauging the load capacity of these jacks.  Therefore, DO NOT EXCEED 80,000 lbs. with either of the two Bridge Jacks.

With this kind of hardware, it's no surprise that the Ellis Bridge Jack can support loads up to 80,000 pounds. A favorite of contractors, they fit directly under concrete slabs or beams in tight spots, as well as with timbers for shoring projects. Just install the Bridge Jack at its closed height of 13.5" (BJ-6) or 19" (BJ-12) and use the 6" (BJ-6) or 12" (BJ-12) of adjustment to screw it into position.  The BJ-12 is designed with a triple lead acme screw for very fast adjustment.

**CAUTION**
The Acme Screw of the Bridge Jack will completely separate from the Acme Nut if screwed out to far.  Do not extend the Acme Screw past the maximum adjustment of 6" (BJ-6) or 12" (BJ-12).  This will insure that all the threads of the Acme Nut will be used to support a heavy load.

Search and Rescue teams also know the value of the Ellis Bridge Jack. With it's ability to fit in tight spaces to stabilize concrete slabs or steel beams, the Ellis Bridge Jack is a versatile tool for downed buildings and reinforcement in small areas. It is strength in a small package, when time is of the essence.
