Helical Pile Installation Machines
Helical piles are typically installed with machinery such as mini-excavators, standard excavators, backhoes, and skid steer loaders. In special circumstances where access is limited, portable installation equipment may be utilized.
The three functions of the machine in helical pile installation are:
- Weight: Since weight is required to resist the torque applied to a helical pile, the installation machine first serves as the foundation for installation.
- Hydraulics: Secondly, the machine’s hydraulic pump serves as the hydraulic supply to the torque motor. Properly matched hydraulic pressure and flow between the machine and torque motor are critical for an efficient installation.
- Movement: Lastly, the machine is used to manipulate, align, and locate the installation of a helical pile. Mobility and/or articulation of the boom greatly improves ease of installation.
Note that a machine is only as good as the operator running the piece of equipment. Properly trained operators with previous helical pile installation experience greatly increases productivity and reduces installation issues.
Four commonly used machines for helical pile installation are mini-excavators, standard excavators, backhoes, and skid steer loaders.
