About Axial-Torsional Grip Installation
Installing the grips in a load unit force train involves attaching one grip onto the
end of the actuator rod and one grip to the force transducer or crosshead. The
grips are mounted to the load unit with axial/torsional couplings. The following
figure shows the components used for most installations.
