Pile Dynamics Analyzer – Dynamic Load Tester (PDA-DLT)

The Pile Dynamics Analyzer – Dynamic Load Tester (PDA-DLT) monitors  high strain dynamic load tests on drilled shafts and bored piles using a drop weight system.

  • Dynamic load testing and monitoring of drilled concrete shafts
  • Up to 16 channels of data acquisition available with eight WIFI boxes and any combination of strains and accelerometers
  • Complete with CAPWAP®, GRLWEAP, and iCAP® software
  • Field-to-office data transmission with SiteLink®

The Pile Dynamics Analyzer – Dynamic Load Tester (PDA-DLT) was designed specifically for quality assurance testing of drilled shafts and bored piles. The PDA-DLT allows for multiple configurations of force measurement. The system acquires data from accelerometers and strain transducers attached to a pile or shaft so that High Strain Dynamic Tests (ASTM D4945) may be performed. The tests require the impact of a suitable drop weight.

The PDA-DLT evaluates:

  • Bearing Capacity
  • Structural Integrity
  • Foundation Stresses

 

The PDA-DLT conforms to ASTM D4945.
