Installing to a Load Frame M10-14179-EN

High Temperature Extension Rods
Figure 3-4 on page 3-5 illustrates a pair of Series 2732 grips installed in a
chamber. Extension rods provide the Series 2732 grips with the maximum amount
of travel within an environmental chamber and carry the air pressure to the grip.
The specific extension rod configuration depends on the size of the chamber,
specimen length and the amount of crosshead travel during the test.
A swivel coupling connects the upper rod to the load cell while a rigid coupling
connects the lower grip to the base plate. All pneumatic connections are outside of
the chamber.
Set mechanical and electronic limits before operating the test system when
you have extension rods installed inside a chamber.
Extension rods restrict the total crosshead travel. The grip will collide with the top
of the chamber if the crosshead travels beyond the travel region.
