LLT-M

Lateral Load Tester 　Type-M

The LLT Type “M” is an in-situ tester to evaluate the mechanical characteristics of soft ground. The LLT operates using inflatable rubber packers and mechanical properties are deduced from the relationship between applied stress and deformation. Three different diameter sondes (60, 70, 80 mm) are available to cover a wide
range of borehole diameters. The water tank consists of four equi-dimensional cylinders enabling the user to select
four different water volumes dependent on the sonde diameter. The whole system is packed in two carrying containers.
The LLT is able to evaluate the following foundation engineering static characteristics of the ground:
Modulus of subgrade reaction･･････K value
Deformation modulus ･･････ E value
Yield strength ･･･････Py

● Both pressure and displacement are measured directly in the probe using electrical transducers.

● Mechanical arm is used for the measurement of displacement making maintenance easier.

● Applied pressure is measured by precise semi-conductor transducer in the probe.
