Model 680.01 High-Temperature Grips Functional Description
The pushrod, grip extension, and replaceable specimen adapters are made of
special alloy steel to withstand high furnace temperatures. The base and the grip
body are cooled by water flowing through internal passages.
The ends of correctly dimensioned button-end specimens are automatically
positioned with proper relationship to the pushrod by specimen adapters.
Viewing ports allow the end of a threaded specimen to be viewed for proper
insertion length into the specimen adapters.
A specimen with appropriate specimen adapters is installed in the grips.
Hydraulic fluid is applied to the pressure ports. The grip pistons move and push
their pushrods against the ends of the specimen. After testing, hydraulic pressure
is removed and the compression springs in each grip retract the pistons and
pushrods, releasing the specimen.
