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. The load frames are built around a robust twin chromed-column structure, ensuring extremely high rigidity. The loading platen is made from stainless steel. 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.

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. 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. 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. 

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. 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.
