Load Frames

Load frame 28-WF4001 with triaxial analogic configuration
Load frames are used for applying vertical force in triaxial and many other laboratory tests where vertical load has to be applied. Six models of load frames are available depending on the maximum capacity and whether they are fitted with a built-in data acquisition. Developed over more than 70 years of continuous innovation, Wykeham Farrance load frames range provides solutions to meet all customer needs, from leading research to Quality Control laboratories.

Description

 

WYKEHAM FARRANCE’s electro-mechanical TRITECH machines are the original high-performance load frames for triaxial tests. Introduced by the company over 50 years ago, they have undergone continuous development and are the ideal solution for advanced and research laboratories that want to perform high quality tests at high levels of productivity.
 
Based on heavy duty triaxial load frames, with advanced electronics and high quality components, these frames are the top of the range currently available for triaxial testing on soil.  They can be used either as part of a computer-controlled automatic testing system or as high-performance stand-alone units under manual (or PC remote) control.


The load frames are built around a robust twin chromed-column structure, ensuring extremely high rigidity. The loading platen is made from stainless steel.
 
When the frame is used in PC control mode, all the main functions (speed fast/slow, direction up/down, stop) are managed by the PC software.  In manual stand-alone mode, the user-friendly keyboard on the front panel is used to control all the frame’s functions, including a rapid approach facility that reduces test set-up time. For efficient use the last settings are automatically recalled after switch on and micro switches prevent over-travel problems.  The panel and display are protected from water and dust by a waterproof membrane.


These frames are versatile, compact and easy to use and allow a variety of test procedures to be performed on samples with diameters from 38 up to 150 mm.  They’ve been specifically designed for soil testing labs conducting UU (unconsolidated unconfined), CU (consolidated Undrained), CD (consolidated drained) and stress path triaxial tests but they can also be used, due to their variable speed range, to perform unconfined, CBR and Marshall tests. 

It requires extenal data acquisition system see our GEODATALOG’s 

Two capacities are available: 28-WF4005 – 50 kN and 28-WF4010 – 100 kN.

A complete range of parts and accessories is available to configure these machines for any typical triaxial soil testing application.

Triaxial load frame TRITECH 50 kN with 4 channels built in data acquisition (model 28-WF4005/4C)
Description

WYKEHAM FARRANCE’s electro-mechanical TRITECH machines are the original high-performance load frames for triaxial tests. Introduced by the company over 50 years ago, they have undergone continuous develop­ment and are the ideal solution for advanced and research laboratories that want to perform high quality tests at high levels of productivity.
Based on heavy duty triaxial load frames, with advanced electronics and high quality components, these frames are the top of the range currently available for triaxial testing on soils. The load frames are built around a robust twin chromed-column structure, ensuring extremely high rigidity. The loading platen is made from stainless steel.
Four models are available depending on the max capacity and if equipped or not with a built-in data acquisition. 

The models are fitted with 4 built-in channels and data acqui­sition, to be used either in stand-alone mode or connected to a PC.
TRITECH 4C are the ideal solution for advanced and research laboratories who require high quality and productivity testing. This model is a stand alone machine that can perform compression/extension triaxial tests, unconfined, CBR, Marshall and general compression tests.
These load frames are equipped with a wide user friendly touch screen display, side mounted and very ergonomic allowing local control of the main functions and data acquisition.
In each model the panel and dis­play are protected from water and dust.
The touch screen display is ex­tremely versatile to start, pause and stop the test, to set up data recording mode, to show live readings of the transducers in real time and to perform calibrations.  In addition a LAN connection and a dedicated software (included with the machine) allows remote control from the PC.  In remote control mode the soft­ware allows the user to control the main functions via PC as well as to calibrate the channels with linear, polynomial and multi-co­efficient calibration mode, and to display the readings.
