The robust, functional design of the apparatus coincides with the well-proven measurement andcontrol electronics which are assisted by a menu-driven system for monitoring and performing complex analyses. Exchangeable, pre-calibrated measuring sensors guarantee high accuracy over a wide measuring range.

The load frame could be equipped with a large range of triaxial cells with different sample sizes and cell pressures, Pressure controlling systems, transducers, controller and dedicated software to run static and cyclic Triaxial tests per as the required standard.

The high quality electromechanical closed-loop controlled triaxial load frames are characterized by their high features for static and cyclic automatic loading possibilities. This high stiffness high quality load frame is useful for many applications in geotechnical testing and comes with different load capacities and frequencies.The Wide column spacing enables to accommodate large cells even with environmental chambers and furnaces and has higher load capacity than table top version.

It comes with two different models:

• Floor type combined static and cyclic load upto 25kN-10Hz

• Twin type load frame (independent cyclicstatic actuators) up to 150kN static load and10kN-10Hz cyclic load.

This Twin solution is for the time which a need of a high static load in combination with standard cyclic load is required for different tests in laboratory and in one frame. Per as several advantages of the electromechanical system to Hydraulic loading frames, this series of machines can meet most of test requirements in the lab.GEOsys software in combination with other components and this loading frame performs all your triaxial tests automatically and without operator assistance during the test period.

Cyclic Electromechanical Load Frame

Cyclic Electromechanical universal load frames driven by an electric motor are increasingly becoming the choice of loading system for many Geotechnical applications in comparison with the equivalent pneumatic or hydraulic loading systems. The frame has a high stiff construction for this application and the system is capable to run the tests from small strains to large strains in static and dynamic modes. The control cabinet is located at bottom of the frame and does not need any additional space.This floor type series come in two versions:

A) Floor Type With Single Actuator

In this version the load applies from bottom and the control cabinet is also located at bottom of the device and total weight of the system makes it also resistance against extra vibration caused by cyclic actuator. It is easy to install and use the loading system in combination with dynamic controller which has different models, triaxial cell, transducers,pressure volume controllers and GEOsys software which enables you not only to run the load frame but also, to run different test applications which is programmed and would be delivered per as your test requirements. Cyclic Load 10kN/25 kN，Frequency10Hz

B) Twin Type Load Frame (Independent cyclic- Static Actuators)

In this series of laod frames, the static load is applied from bottom and has its own servomotor and controlling unit and the cyclic actuator is placed on upper traverse and has dedicated dynamic controller to run all cyclic loads required for different applications. All connections are designed and manufactured to enable running the system in a smooth way even when the exchange of static to cyclic load is required.

Soil Triaxial Cell

This series of Stress path Triaxial cells designed for static and dynamic soil testing to test cylindrical soil specimens with diameters from 38mm up to 150 mm, a length/diameter ratio of at least 2 under triaxial conditions. The cells cover variety range of tests which is required in the geotechnical labs.

Static Cell And Back Pressure System

The cell and back pressure can be generated and controlled automatically by different configurations depends on the testing applications, laboratory utilities and technical requirements in a variety range of pressure and for different applications With both below configuration which automatic and are controlled via PC, Tests such as Saturation, stress/strain path, permeability, K0 and other tests can be easily performed with accuracy and precision.

A) Air Pressure Controller (APC)

The standard configuration of this series includes of one-off Air pressure controller (APC) to generate air pressures (e.g. confining and pore pressure), two-off Air/Water Bladder which acts as an interface to exchange pneumatic pressure into hydraulic pressure and one -off automatic water volume measuring device to measure volume changes.

This system is fully automatic system and is controlled via PC and dedicated software.

Working pressure: 2 MPa    Pressure outlet：3 for inner cell, outer cell and backpressure

B) Volume Pressure Controller (VPC)

This method included of two Volume Pressure controllers for applying back pressure and Cell pressure. These are syringe pulse-less pumps which generate and regulate pressure and provide flow control in a variety range for different testing requirements.

The control of the units is simply done via Touch-panel for stand-alone use or via PC and dedicated software. This making them very convenient and easy to operate.

Digital Controller

Digital High-Speed High Resolution Expandable Real Time Control and data acquisition System 10KHz control and data acquisition and 24 bit resolution. The Dynamic controller is suitable for screw driven instruments(electromechanical) , hydraulic instruments with a valve driven with ±10 Volt and variety of sensors e.g. load cells, LVDTs, strain gauges, extensometers, thermocouples and etc.

The multi-functionality of the controller allows a modular design of the measurement and control parameters (sensors) via intelligent sensor plug, which store the calibration parameters, thus depending on the application can be used flexibly.
