Pile Testing Equipment: PDR


Pile Testing Equipment: PDR


Allnamics has developed a state-of-the-art multi-purpose monitoring system, the PDR.  The PDR is an advanced Wi-Fi based pile testing monitoring system for Pile Driving Analysis (for both impact (PDA) and vibratory hammers (VDA)), Dynamic Load Testing (DLT or PDA Test), and Rapid Load Testing (RLT -Statnamic(STN) and StatRapid(STR)). 


A multi-disciplinary design team, supervised by Peter Middendorp and Fokke Reiding (the original developers of the first portable pile testing systems, (including the TNO Pile Driving Analyser), created this product, which meets the pile testing requirements on the construction site in every respect.


Options include continuous monitoring of strain and acceleration during pile driving (PDA) and single blow registration for Dynamic Load Testing (DLT - or PDA Test) during re-strike.  Data collected for the latter can be exported for further analysis with the AllWave-DLT signal matching software.  Additionally load cell and accelerometer data can be recorded during Rapid Load Testing (e.g. Statnamic™, Statrapid™).
