Torque Spool - Screw Pile Torque Measuring System

Utilising the same technology as the Torque Hub, the Torque Spool screw pile measuring system delivers over 99% accurate torque readings. Data is sent over a robust 2.4 GHz RF FHSS signal to a smartphone via the TorqApp. The Torque Spool measures not only torque, but also inclination. This pile torque monitoring and data logging device is mounted between the output shaft and drive tool. To suit MD, UD and XD anchor drives (110,000 Nm to 500,000 Nm).

Installation Torque Reporting

Reports can be exportable directly from your smart device via email using a smartphone with its’ hotspot enabled via the TorqApp.

The TorqApp is FREE to download from either the Apple App Store or Google Play.
