Product Description
Helical anchors are a deep foundation system. It consists of a central shaft of various diameters, thicknesses, and spiral plates. The diameters of helical plates depend upon soil conditions and loading.
A complete Power Shaft Assembly consists of a lead helix section, extension(s) and guy termination other attachment. The helix size (diameter) and number of helices are selected for the required holding strength. The shaft size and rating is selected based on the necessary holding strength and installation torque requirement. The guy attachment is chosen based on the number of guys
Extensions with helix are placed directly after the lead section (no bare extensions in between). They are used when additional bearing area is needed and to develop increased installation torque. Specifications:

Shaft material: Seamless high tensile pipe, conforms to ASTM A500 GRADE B
Helices material: ASTM A36 Hot rolled plate
Corrosion protection conform to ASTM A153 standard for hot dipped zinc coating
Leading edge of Helices beveled 45 degrees
Greater Section Modulus Strength to resist Twisting and Deflection
Greater Load Capacities
Hot Dip Galvanized per ASTM A123.
Consists of solid square shafts, ranging from 1.5″ to 2″. The piles are typically used for ultimate loads between 100 and 650 kN (25-150 kips) but have been tested to loads in excess of 900 kN (200 kips) in unique situations.
Square shaft products are generally used in small to moderate loading applications, and they provide excellent tension resistance. Square shaft piles are able to penetrate dense and cobble-rich soil when compared to their helical pipe pile equivalents, but they have lower resistance to buckling and negligible lateral load resistance.
In applications where tension is the primary consideration, we recommend the Square Shaft Piers. They have several advantages over the typical square shaft anchors.
Square Shaft Advantages:
• Greater yield and Tensile strength
• Patented Cross-bolt Connection
• Increased safety factor
• Higher torque capacity
• Easy to install
• Installs in any season
• Minimal soil disturbance
• Not affected by a high water table
Composition:
• square solid shaft 1 1/2" thru 2″ O.D. typical.
• Solid round cornered Square (RCS), yield strength of grade 70 or 90.
• Ultimate compression/tension axial capacity: 57 to 200 kip.
• Circular tapered plates (helices) are welded to the center of the shaft.
• Helix diameters can range between 6″ - 48″
• with a thickness of 3/8″ - 1″.
• Helix pitch will range from 3″ - 6″
• Hot dipped galvanized per ASTM A123 or bare steel options available
• Coupling bolts are heavy hex bolt as per ASTM A325
• All welding to be done by welders certified of the AWS CODE D1.1 Packaging & Shipping
