MTS Series 647 Hydraulic Wedge Grips - Manual (Page 48)

3.
Warning:
The upper grips are very top heavy and will have a tendency to tip over when lifted by the
double swivel eyebolts.
Dropped grips can cause injury to personnel and damage to equipment.
Never attempt to control the grip by holding onto the eyebolts. Use the connector stud to help
control the grip balance.
Mount the upper grip to the force transducer on the crosshead using an adapter between the force
transducer and the upper grip.
a) Place the load transducer mating adapter against the force transducer and thread the socket head cap
screws into the force transducer until they are finger tight.
b) Using the sequence shown in the figure to the right, torque the socket head screws first to 10%, then
to 50%, and finally to 100% of the torque specified on the attachment kit drawing (MTS part number
469615-xx).
c) Remove the socket head cap screws from the upper coupling and place the screws and coupling halves
within easy reach and oriented properly for installation on the grips.
d) Place a wooden spacer (a wood block or piece of plywood) on top of the lower grip. The wooden spacer
should be large enough to cover the diameter of the grip.
