IMPORTANT NOTE:
The capacities listed are mechanical ratings. One must understand that the actual installed load capacities are dependent upon the actual soil conditions on a specific job site and the strength of the termination connection. The useable shaft torsional strengths given here are the maximum values that should be applied to the product. Furthermore, these torsional ratings assume homogeneous soil conditions and proper alignment of the drive motor. In homogeneous soils it might be possible to achieve 90% to 95% of the ultimate torsional strength shown in the table. The designer should select a product that provides adequate additional torsional capacity for the specific project and soil conditions. |
