Note:
You will need to construct a proper support or have someone available to help balance the upper
grip on the lower grip.
c) Carefully position the grip on top of the wooden spacer on the lower grip.
d) You might need to insert double swivel eyebolts into the threaded holes on the grip chamber. Attach
a lifting device to the double swivel eyebolts and position the grip on top of the lower grip.
e) With the connector stud facing up, add any required shims, spacers, or spiral washers to the stud.
f) Turn on hydraulic pressure and slowly raise the lower grip until the stud on the upper grip just makes
contact with the force transducer. Reposition the grip, as necessary, for proper thread alignment.
g) Slowly screw the grip into the force transducer until it is snug.
h) Raise the crosshead to accommodate the environmental chamber.
5. Install the environmental chamber.
Position the environmental chamber (with its cart) in the load unit so that the holes in the chamber are
aligned with the force train. Secure the cart.
Note:
The environmental chamber might need to be repositioned to achieve proper alignment with the
grip components.
See the environmental chamber documentation for more information.
