Testconsult's Auto Static Load Test (ASLT) system is purpose designed to control and monitor static load tests automatically.
The ASLT system is supplied with a rugged site notebook, pre-loaded with the ASLT controlling software and calibration for the transducers.
The system incorporates a data acquisition battery back-up, which allows testing to continue in the event of a power failure, without the loss of any intelligence.
Improved safety features enable you to monitor tests from a safe distance of up to 25 meters, removing the need for operatives to be in close proximity to potentially dangerous, highly loaded system components.

Data acquisition, pump control and data storage is all controlled by the user friendly ASLT software, and operated within Windows operating systems.
The software enables the operator to set up and save loading templates, as well as review and alter alarm settings accordingly. As the test proceeds the user can view all of the data in real-time and view plots of load versus settlement.
Displacement gauges can be calibrated in-situ with supplied gauge block and re-set remotely. Should the test be halted for any reason e.g. power failure, there are routines which enable the test to recommence without any loss of data.
The load, deflection and load maintainer readings are collected by the ASLT data logger and downloaded to a rugged on site PC. All data is presented in accordance with Eurocode7-EN-1997, the European standard for design of geotechnical structures.
Our user friendly system allows data to be viewed in real-time, comparing plots of load versus settlement as testing progresses. The software enables users to set up and save loading templates, and to also review and alter alarm settings accordingly.
