Chance Foundation Solutions Type RS7000.362 Helical Piles (TD03321E) are engineered to provide exceptional support and stability in various soil conditions. With an impressive ultimate capacity of 360 kips and an allowable capacity of 180 kips in both compression and tension, these helical piles offer reliable load-bearing capabilities.

The piles feature a 7-inch diameter, 0.362-inch wall, round HSS shaft with sleeve couplings, ensuring structural integrity and enhanced resistance to lateral forces compared to solid square shafts. The 6-inch helix pitch, along with the availability of various helix diameters (16-26 inches), allows for customization based on specific project requirements.

CHANCE® Type RS7000.362 Helical Piles
360 kip Ultimate – 180 kip Allowable Capacity
Installation Torque Rating – 90,000 ft-lb
Multi-Purpose 7” Diameter, 0.362” Wall, Round HSS Shaft with Sleeve Couplings
Description:
Hubbell Power Systems, Inc. / CHANCE Type RS7000.362 Helical Piles have 360-kip ultimate capacity and 180-kip
working or allowable capacity in compression or tension. This capacity is based on well documented correlations
with installation torque, which is recognized as one method to determine capacity per IBC Section 1810.3.3.1.9. Lead
sections and extensions couple together to extend the helix bearing plates to the required load bearing stratum.
Round shaft helical piles oer increased lateral and buckling resistance compared to solid square shafts with similar
torque strength. Strength calculations are based on an average life expectancy of 50 years for most soil conditions.
CHANCE Type RS helical piles and anchors feature straight leading edge helix plates that are circular in plan to
provide uniform load bearing in most soil conditions. Custom lengths and helix configurations are available upon
request. See page 2 for additional information and specifications.

Helical Pile Shaft
Cross-Section
RS5500.361 Helical Pile Specifications & Available Configurations
Shaft – HSS 7 inch OD x 0.362 inch wall steel shaft produced exclusively for CHANCE products.
Coupling – welded internal sleeve forming a flush fit joint connected with multiple structural grade bolts.
Helix - 1/2 and 5/8 inch Thick: ASTM A656 with minimum yield strength of 80 ksi, and ASTM A572 with minimum
yield strength of 50 ksi, depending on helix diameter.
6 inch Helix Pitch – a Standard established by CHANCE for larger diameter Helical Anchors & Piles
Available Helix Diameters: 16, 18, 20, 22, 24 and 26 inches
All helix plates are spaced 3 times the diameter of the preceding (lower) helix unless otherwise specified.
The standard helix plate has straight leading edges.
Configurations:
• Single, double, triple, lead sections, 10 feet long
• Plain extensions, 3-1/2, 5, 7, 10, 15, and 21 feet long
• Extensions with helix plates, 5 and 7 feet long
Helical products are hot dip galvanized per ASTM A123 Grade 75, or are available black.
NOTE: Helical piles shall be installed to appropriate depth in suitable bearing stratum as determined by the geotechnical engineer
or local jurisdictional authority. Torque correlated capacities are based on installing the pile to its torque rating, using consistent
rate of advance and RPM. A minimum factor of safety of 2 is recommended for determining allowable capacity from correlations.
Deflections of 0.25 to 0.50 inches are typical at allowable capacity.
