What Specialized Hydraulic Equipment is Required for Helical Pier Installation?
Installing helical piers requires a specialized hydraulic system designed to provide the rotational force necessary to screw the steel shafts into the ground. The core equipment components include:
- Hydraulic Torque Motor: This is the central component, typically sized between 5,000 and 15,000+ ft-lb for most structural applications. It provides the rotational force required to advance the pier.
- Hydraulic Power Unit: This unit powers the motor and can be diesel or electric-powered depending on the specific site access requirements.
- Drive Tooling: Specialized tools that couple the hydraulic motor to the pier shaft, often utilizing an adapter bracket or a universal drive cap.
- Installation Platforms: Standard installations typically utilize a skid-steer or mini-excavator equipped with the torque motor. For restricted areas, such as basements or crawl spaces, compact power units or low-profile tooling (capable of operating in as little as 4 feet of headroom) are required.
- Monitoring Equipment: A pressure transducer is placed inline with the hydraulic system to convert hydraulic pressure into torque output. This is used in conjunction with a datalogger or electronic torque recorder to provide real-time verification of the pier’s load-bearing capacity.
