The testing (PoT) or Pull Out Test, are tests carried out to know if a terrain is suitable for driving pile, generally for piles installations for solar parks, and for this task the load capacity of the piles will be measured.

All posts or piles to be driven must be tested with two types of loads:

1.- Lateral Force V: applied against the flanges of the posts, that is, along the network of the cross section.
2.- Axial or Vertical Force N: along the length of the beam trying to push it to the ground (compression) or trying to pull it off the ground (tension).

Vertical Force (Compression): Apply the load with a rigid steel frame and a pile to apply the pressure load with the loading machine. The dial indicator, which measures displacement, is placed 25mm from the same surface. In the next photo you can see the arrangement to apply load and measure displacement during the vertical compression test.

Vertical Force (Tension):
Attach the pull machine to the top of the pole or pierce the pole band and use shackles, straps, and the digital dynamometer. The dial indicator, which measures displacement, is placed 25mm from the same surface. The following photos show the provisions for applying load and measuring displacement during the vertical tension test.
