Ellis Heavy Duty Steel Lifting Shores are for temporary or permanent shoring applications. Use the Ellis Heavy Duty Shore to support up to 56,000 lbs. To use measure shoring height, select the appropriate Ellis Heavy Duty Steel Shore, set shore in place, use 1" Steel Adjustment Rods to adjust height. Once shore is in place and adjusted to desired height simply tighten set screw (on side of nut) to lock nut to set shore for permanent support solution. These shores are also know as jack posts.

Thrust Bearings & Safety Lock - This patented design, found in Light and Heavy Duty Steel Shores, greatly reduces the amount of friction caused when adjustment to the nut is made when the shore is under load and significantly increases its jacking capability. Unlike the standard steel shore, thrust bearing shores are built as one complete unit to aid in uplift resistance and do not come apart. We have also added the Safety Lock set screw in the side of the nut. When tightened down, the adjustment nut locks in place for permanent or long term shoring applications.

*All Load Capacities include a 2.5 to 1 Factor of Safety.
*Steel Shores should be attached to a flat solid foundation and should not be subject to any lateral force. Heavy Duty Steel Shores should be used to support straight vertical loads only. We recommend tightening set screw in the side of the 4 hole nut with 6mm allen wrench prior to loading (unless lifting). Before construction begins it is recommended that you consult with certified engineer for approval of our products within your application.
