Single Solid Square Hub Power Driven Anchor

• Installation is performed using apower digger. An anchor wrench fitsover the anchor hub and a torquemeasurement device is required todetermine proper installation.

• Correct installation is achieved onlywhen the anchor is installed using theappropriate torque for the particularsoil and anchor type (see referencecharts).

• Proper anchor selection depends on the type of soil and guying requirements.

• Installation torque is usually measuredusing a device connected in series with the wrench, digger, and Kelley Bar during installation.

• Anchors are painted with rust inhibitingblue paint after fabrication.

Estimated Anchor Holding Strength

Soil Class Description

• Holding strengths given are mid-range values for each soil class.• Holding strengths given are mid-range values to aid initialanchor selection.

• Variations of 10% or more in some cases can be expecteddepending on soil variations and conditions.

• In general the higher soil classes have lower variations.

CLASS DESCRIPTION

2 Dense sand, hard silts, course gravel. Probe value 600-750 inch lbs.

3 Compact clay and gravel mixed, shale, broken rock, hardpan. Probe value 500-600 inch lbs.

4 Compact sand, claypan, compacted gravel. Probe value 400-500 inch lbs.

5 Loose sand, gravel and clay, compacted course sand. Probe value 300-400 inch lbs.

6 Clay loam, damp clay, compacted sand fines, loose course sand. Probe value 200-300 inch lbs.

7 Silt loam, loose sand fines, wet clay, miscellaneous fill. Probe value 100-200 inch lbs.

8 Swamp, saturated loam, marshland (anchor should penetrate through saturated strata to Class 5, 6, or 7 for best results)

• Anchors with 4" - 8" - 10" helices and with 6" - 8" - 10" helices should be consideredappropriate for soil conditions in which the anchor encounters a transition to dense soil following installation into moderate or low density soils.

• Anchors with 14" - 14" - 14" helices should be considered appropriate only for very lowdensity soils.

• Torques vary widely, depending on soil type. Ratios of capacity in kips (Kilo Pounds) totorque in ft. lbs. can vary widely over a range as large as 8 to 25 times, depending onanchor configuration and soil type. Once the soil reaction is established, torque can beused as a predictor of capacity. When torque ratios are used an average torque over thelast 2 or 3 feet (or 3 times the diameter of the upper helix) of the installation is thetorque that should be used. For Multi Helix Anchors, final installation torque can bevery misleading.
