Loosen the contact pad capscrews and nuts.
NOTE:
It is not necessary to remove the capscrews
and nuts to insert the shims.
5
Install shims as required.
•
Positive Camber –
Install shims at the bottom and
middle of the pad to increase clamp force at the
bottom of the load.
NOTE:
This will increase the clamp force
percentages on the lower spindles readout of the
4-Point Force Distribution Tester.
•
Negative Camber –
Install shims at the top and
middle of the pad to decrease clamp force at the
bottom of the load.
NOTE:
This will increase the clamp force
percentages on the upper spindles readout of the
4-Point Force Distribution Tester.
CAUTION:
Use an equal number of shims on each
contact pad. Pad camber must be the same on both
sides of the attachment for proper load handling.
