NOTES:
1. These are mechanical capacity ratings. Foundation strength and soil capacity will dictate actual capacity.
2. Bracket Lift Height Can Easily Be Increased By Ordering Longer Continuously Threaded Bracket Rods.
3. The TAB-LUB Bracket is the same component for three different shaft sizes; the Pile Cap configuration varies to accommodate the appropriate shaft for the application.

* Load transfer and elevation recovery is accomplished using ECP Steel Pier™ Bracket Lift Assemblies (Purchased Separately) The TAB-150-HSB and TAB-288-LHSB Bracket requires an ECP Model 300 Lift Assembly and the TAB-288-HSB Bracket requires an ECP Model 350 Lift Assembly.
The capacities listed for foundation brackets are mechanical ratings, and the actual installed load capacities are dependent upon the strength and condition of the concrete, and the specific soil conditions on the job site. Concrete strength for the above ratings was assumed to be 3,000 psi.
Bracket lift height may be increased by ordering longer continuously threaded bracket rods.
Capacities based upon “soft” soil values “N” > 5 blows per foot
Special configurations to fit your project can be fabricated to your specifications upon request. Allow extra time for processing.

Pile Cap Notes:
1. Capacities based upon 3,000 psi concrete. Reduce loading or increase plate area appropriately for lower strength concrete.
2. Pile caps shown are standard items and are usually available from stock. Note: TAB-288L-T and TAB-288-T are not interchangeable because bolt hole spacing varies.
3. Part numbers for tension include attachment holes and SAE J429 Grade 8 hardware as shown; compression pile caps do not include hardware or mounting holes.
4. Compressive capacity ratings of some pile caps are limited by compressive pile shaft capacity.
5. Pile caps are supplied plain steel -- hot dip galvanized per ASTM A123 Grade 100 is available.
6. Configuration for the TAB-225 N/C 1 (12 x 12) Pile Cap is slightly different than illustrations
*Custom fabricated pile caps are available for all shaft sizes by special order – allow extra time for processing.

ECP Plate Anchor Kit
ECP Earth Plate Anchors are supplied as illustrated below. The wall plate area is 2.2 ft2 and the soil bearing area is 3.0 ft2. The ultimate-limit tension capacity is 10,000 lb. The plate spacing is adjustable from 9 ft to 17-1/2 ft. (Details on pages 99-101)
The sketch above shows the components that are shipped with solid bar transition assemblies. The Transition and the hardware required to attach the Transition to the Tieback will vary depending upon the product ordered. Please refer to the table above for additional details. Tubular transitions and TAT-225 do not include a flat wall plate. As the angle of installation usually varies generally from 150 to 300, bevel washers should be ordered separately.
