Hoek Cells are used to conduct triaxial tests of rock specimens. They are available configured for different rock cylinder diameters and or commonly used with resistive strain gauges fixed directly to the test cylinders.
Hoek Cells comprise a steel body complete with two quick release self-sealing couplings for oil inlet and outlet, two steel hollow end caps which are screwed to the cell body, a rubber sealing sleeve, an upper and a lower loading caps with spherical coupling, an upper and a lower spherical seat pistons, two pieces end caps and two load spreaders.
