APA Solar - A-Frame Tracker for Soil and Frost Conditions
The dual post design is ideal for tracker sites with challenging soils or ground frost considerations. Traditional piles rely on skin friction for pull out values and deep embedment depths to combat frost heave. With a dual post system, the loads are spread out differently allowing for lighter weight material, less surface area and shallower depths.
- Helical or screw foundations are standard, and often more cost effective than traditional I-beams.
- Standard tracker connection allows for a seamless transition from I-beams to the A-Frames.
- Leveling flanges allow for adjustment on sites with topography.
- Less weight than traditional pile foundations.
- Material: High Strength Steel
- Coating: ATSM 123
- Foundation: Helical or Screw
- Anchor Depth: Varies based on project
- Adjust-ability: 20″ with telescoping posts
- PE Stamp: APA Drawings can be PE stamped for all 50 States
The A-Frame Tracker foundation is compatible with helical or ground screw options.
Helical foundations are available in 3.5″ up to 10″ in diameter, and are a cost effective option for most soil types.
ScrewScrew foundations are available in 47″ to 85″ lengths, and are ideal for soils that contain glacial till, cobble and hardpan.
