Dynamic Load Tester for Drilled Shafts
Complete with CAPWAP®, GRLWEAP, and iCAP® software
Bearing Capacity Evaluation
16 channels of data acquisition available with eight wifi boxes
Field-to-office data transmission with SiteLink®
Foundation Stresses Evaluation

The Pile Dynamics Analyzer – Dynamic Load Tester 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:
